SPI導(dǎo)電銀膠05063-AB/銀膏

所有的銀膠銀膏在這一頁(yè)列出的已被設(shè)計(jì)為特定的顯微鏡的實(shí)驗(yàn)室應(yīng)用程序，但我們也知道，所有這些都可以用來(lái)使任何表面導(dǎo)電。我們提供以下意見(jiàn)，以幫助那些試圖決定這些不同的產(chǎn)品將是自己的特殊應(yīng)用。請(qǐng)記住，銀膠和膏體的zui終特性是從各自的金屬的固有特性，即是銀或鉑。

顯微鏡中的應(yīng)用：

SPI品牌銀膠廣泛應(yīng)用在世界各地的的實(shí)驗(yàn)室，掃描電子顯微鏡（SEM）和掃描探針顯微鏡（SPM）進(jìn)行。銀的純度高和固體懸浮介質(zhì)使SPI*品牌在這些種類(lèi)的顯微鏡進(jìn)行。

電導(dǎo)率：

所有這些銀膠產(chǎn)品都有導(dǎo)電性。然而，碳涂料，雖然它有足夠的導(dǎo)電性，其用于掃描電子顯微鏡的接地試樣的使用，可能沒(méi)有足夠的導(dǎo)電性的其他應(yīng)用程序，如電鍍。一個(gè)人必須嘗試，以找出它是否會(huì)在自己特定的電鍍應(yīng)用程序工作。銀和鉑漆產(chǎn)品的導(dǎo)電性比碳漆產(chǎn)品多，而且也更貴。

SPI銀漿加是一種高純度、均勻、粘稠的銀顆粒懸浮，理想的掃描電鏡的使用，特別是安裝多孔樣品在毛細(xì)管作用將是一個(gè)問(wèn)題。雖然此產(chǎn)品需要更長(zhǎng)的干燥時(shí)間比其他所有的銀漆產(chǎn)品，它具有很高的導(dǎo)電性和無(wú)“芯”的多孔樣品可以選擇安裝介質(zhì)很多SEM實(shí)驗(yàn)室*。

我們也可以報(bào)告大量的固化銀膜產(chǎn)生的SPI銀糊劑加™使用物理力學(xué)性能數(shù)據(jù)。
“商業(yè)”信息：
我們很努力地嘗試不太“商業(yè)化”，但在這種情況下，我們必須作出兩點(diǎn)：
SPI銀漿加72%銀固體。如果你看到了一個(gè)較低的價(jià)格，機(jī)會(huì)是，銀固體含量低，以及！SPI產(chǎn)品是高純度的銀，純度較低的銀總是與它相關(guān)的還有一個(gè)較低的價(jià)格。
小批量產(chǎn)品的“管材”的成本很高。它是便宜得多，在包裝方面，提供粘貼在一個(gè)廣口瓶，這正好是由別人選擇的包。但在蓋上幾次后，承運(yùn)人，這是有點(diǎn)不穩(wěn)定，變干了，并指出，大部分的產(chǎn)品不能使用。但隨著SPI銀漿加在擠壓管，我們的客戶從來(lái)沒(méi)有這個(gè)問(wèn)題。
SPI銀漿加封裝在一個(gè)金屬的擠壓管，操作簡(jiǎn)便，使用方便，保質(zhì)期長(zhǎng)，*次使用后。不同的產(chǎn)品包裝在一個(gè)廣口瓶，SPI銀漿加不會(huì)干出成一個(gè)堅(jiān)硬的“磚”，經(jīng)過(guò)短短幾年的用途。粘度是比較典型的牙膏；需要“瘦下來(lái)”某種程度上糊，它具有較低的粘度，我們會(huì)建議使用SPI的銀漆稀釋劑。

SPI銀漿加zui初開(kāi)發(fā)用于粘結(jié)基材為均勻的溫度分布大面積的加熱頭的問(wèn)題，如在薄膜沉積氧化物超導(dǎo)體。在這個(gè)過(guò)程中，我們創(chuàng)建了一個(gè)更好的產(chǎn)品掃描電鏡樣品制備。
*特色的SPI銀漿加導(dǎo)致其使用范圍外的SEM。如果你也考慮到掃描電鏡的領(lǐng)域中使用該產(chǎn)品，例如，“膠水”的晶片，加熱頭或使用的附件的引線，熟悉這種材料的性能和一些建議的方式，它應(yīng)該使用。也一定要做大量的測(cè)試，以驗(yàn)證是否合適的銀膏加為你自己的非掃描電鏡應(yīng)用。

干燥條件：
SPI銀漿加則是一個(gè)空氣干燥產(chǎn)品。只需要多長(zhǎng)時(shí)間干*將取決于厚度的粘貼，沉積。干燥可以加快應(yīng)用程序的熱量，如果這是這樣做，我們建議的加熱速度不超過(guò)1攝氏度/分鐘，以避免“碰撞”。重要的是，該載體被允許退出的銀層的擴(kuò)散，從而不會(huì)破壞的銀層。

高溫限制：
雖然銀金屬的熔點(diǎn)是961.78°C（1763。2°F），從實(shí)用的角度來(lái)看，一個(gè)從來(lái)沒(méi)有談到在使用條款接近這個(gè)溫度，因?yàn)槌?的氧化和硫化時(shí)，在空氣中加熱時(shí)，什么是一般不知道的是，即使在真空中，金屬開(kāi)始升華為400°C（752°F）和500°C（932°F），升華速率是足夠大的，一個(gè)不能走的更高，沒(méi)有造成問(wèn)題的真空系統(tǒng)風(fēng)險(xiǎn)（有些人會(huì)說(shuō)，這個(gè)臨界溫度低）。如果你在較高的溫度下，對(duì)這類(lèi)產(chǎn)品的需要，請(qǐng)向SPI鉑漆。請(qǐng)記住，每克的鉑的價(jià)格大約是銀的100倍，所以不要太震驚，在同等類(lèi)型的產(chǎn)品在白金的高價(jià)格！

低溫應(yīng)用：
SPI銀漿加經(jīng)常用于引導(dǎo)，然后暴露在低溫下的附件。然而，人們必須意識(shí)到，這種債券的實(shí)力并不是zui大的，但它是足夠的，至少在一個(gè)良好的數(shù)量的情況下，做所需的工作..我們常常要求“將它工作”，我們自己的感覺(jué)是，雖然有理由希望它會(huì)更好地工作的原因，問(wèn)題是，似乎沒(méi)有任何其他選擇。因?yàn)樗堑?，所以它?ldquo;作品”至少有一些研究人員，因?yàn)樗堑摹?/p>

Silver Paints/Pastes
All of paints and pastes listed on this page have been designed for specific microscopy laboratory applications, but we also know that all of them can be used to make any surface conductive. We offer the following comments to help those trying to decide which of these various products would be the most appropriate for their own particular application. Remember that the ultimate characteristics of the paints and pastes spring from the inherent properties of the respective metals, those being either silver or platinum.

Applications in microscopy:
The SPI Supplies Brand of silver paints are used widely throughout the world in the leading laboratories where scanning electron microscopy (SEM) and scanning probe microscopy (SPM) is performed. The high purity of the silver solids and suspending medium make the SPI Supplies Brand the preferred brand wherever these kinds of microscopy are performed.

Conductivity:
All of these paint products are electrically conductive. The carbon paint, however, while it is sufficiently conductive for its intended use for the grounding specimens for scanning electron microscopy, may not be sufficiently conductive for other applications, such as plating. One would have to try it in order to find out if it would work in their own specific plating application. The silver and platinum paint products are much more conductive than the carbon paint products, but also more expensive.

SPI Supplies Silver Paste Plus 30g Tube, CAS #7440-22-4
Item Number 05063-AB
Chemical Symbol: Ag
CAS #: 7440-22-4
Atomic Number: 47
Atomic Weight: 107.8682
Color: Silver
Melting Point: 961.78°C (1763.2°F)

SPI Silver Paste Plus is a high purity, uniform, viscous silver particle suspension, ideal for SEM use, especially for the mounting of porous samples where capillary action would be a problem. Although this product requires a longer drying time than all other silver paint products, its very high conductivity and absence of "wicking" into porous samples makes it the mounting medium of choice for many SEM laboratories worldwide.

We also can report a considerable amount of data on the physical and mechanical properties of the cured silver films that result from the use of the SPI Supplies Silver Paste Plus™.

"Commercial" message:
We try very hard to not appear to be too "commercial" but in this case we must make two points:

The SPI Silver Paste Plus has 72% silver solids. If you see a paste for a lower price, chances are, the silver solids content is lower as well! The SPI product is high purity silver where as a lower purity silver invariably has associated with it a lower price as well.
There are high costs associated with the "tubing" of products in small quantities. It is much cheaper, in terms of packaging, to offer the paste in a wide mouth jar, which happens to be the package of choice by others. But after the cap is removed several times, the carrier, which is somewhat volatile, dries out, and to the point that the bulk of the product can not be used. But with the SPI Silver Paste Plus in a squeeze tube, our customers never had this problem.
SPI Silver Paste Plus is packaged in a metal squeeze tube for ease of handling, convenient application, and long shelf life after first use. Unlike products packaged in a wide mouth jar, the SPI Silver Paste Plus will not dry out into a hard "brick" after just a few uses. The viscosity is comparable to a typical toothpaste; should the need arise to "thin down" to some degree the paste so that it has a lower viscosity, we would recommend using the SPI Supplies Silver Paint Thinner.

SPI Silver Paste Plus was originally developed for the problem of bonding substrates to heater heads for uniform temperature distribution over large areas, such as in deposition of thin film oxide superconductors. In the process, we created an even better product for SEM sample preparation.

The unique characteristics of SPI Silver Paste Plus have led to its use in areas outside of SEM. If you too contemplate usage of this product in areas outside of SEM, for example, to "glue" down wafers to heater heads or to use for the attachment of leads, be familiar with the properties of this material and some of the recommended ways it should be used. Also be certain to do extensive testing to validate the appropriateness of Silver Paste Plus for your own non-SEM application.

Drying conditions:
SPI Silver Paste Plus was formulated to be an air drying product. Just how long it will take to dry compley will depend on the thickness of the paste that is deposited. The drying can be speeded up with the application of heat and if this is done, we would suggest a heating rate of not faster than 1 C°/minute in order to avoid "bumping". It is important that the carrier be allowed to exit the silver layer by diffusion so as to not otherwise disrupt the silver layer.

High temperature limits:
Although the melting point of silver metal is reported to be 961.78°C (1763. 2°F), from a practical standpoint, one never comes close to this temperature in terms of use, because in addition to the well known oxidation and sulfiding that occurs when heated in air, what is not generally known is that even in vacuum, the metal starts to sublime on the order of 400°C (752°F) and by 500°C (932°F), the sublimation rate is sufficiently great that one can not go higher without running the risk of causing problems to their vacuum system (some would say this critical temperature is lower). If you have the need for this type of product at higher temperatures, we refer you to SPI Platinum Paint. Just remember that the price per gram of Pt is roughly 100 times that of Ag, so don't be too shocked at the high price of the equivalent kind of product in platinum!

Cryogenic applications:
The SPI Silver Paste Plus is often times used for the attachment of leads that are then exposed to cryogenic temperatures. However one must realize that the strength of such bonds is not the greatest but it is sufficient, at least in a good number of instances, to do the needed job.. We are often times asks "will it work" and our own feeling is that while there are reasons why one would wish it would work better, the problem is that there just does not seem to be any other alternatives. So it "works" for at least some researchers because it is the best that there is.
