硅钼棒生产工艺

2013 年 9 月 12 日 by Elva

这边呢，介绍一下硅钼棒也就是二硅化钼棒的生产工艺。 1. 制备MoSi2基础料：采用高纯度的金属原料Mo粉、Si粉、W粉、 Ta粉，通过自蔓延合成放热反应（自蔓延是利用化学反应自身放热合成材料的一种技术，又被称为燃烧合成），制得硅钼棒制品的基础组份原料。具体步骤如下： 1）将Mo粉、 Si粉、W粉、Ta粉加入球磨罐内混和、球磨，并按料：球＝4∶9（重量比）加入碳化钨磨球，充氮气后一起球磨20～24小时； 2）自蔓延合成反应，将粉料装入反应釜中... ...Read More>>

什么是硅钼棒？

2013 年 9 月 11 日 by Elva

嗯，好久不见了，亲们，下午好~ 今天呢，跟我们就来说说什么是硅钼棒？硅钼棒呢，就是二硅化钼棒，其主要成分为高纯度的二硅化钼。二硅化钼特点如下： 1.极好的高温抗氧化性，抗氧化温度高达1600℃以上，与SiC相当； 2.有适中的密度(6.24g/cm3)； 3.较低的热膨胀系数(8.1×10-6K-1)； 4.良好的电热传导性； 5.较高的脆韧转变温度(1000℃)以下有陶瓷般的硬脆性，在1000℃以上呈金属般的软塑性。由于具备以上特点，MoSi被广泛用作发热元件、集成电路、高... ...Read More>>

Molybdenum Bar Or Molybdenum Rod？

2013 年 8 月 20 日 by Elva

A few days ago, I asked my collague Sarah who in charge of molybdenum bussiness a question that What Is Molybdenum Bar and What Is Molybdenum Rod? I always can not distinguish molybdenum bar from molybdenum rod cleanly. Now, with the help of Sarah I can do it. Here, I want to share it with you and wish anyone can give any suggestions or doubt to me in what I mentioned in the following. What is molybdenum bar and molybdenum rod? The cross sections of molybdenum bar have many shapes, it may be square, triangular, hexagonal etc., but, if the cross section is round it must be called rod. T... ...Read More>>

Molybdenum Sputtering Target

2013 年 8 月 19 日 by Elva

What is molybdenum sputtering target? Molybdenum sputtering target is a product with high standard, and metallic silver luster surface color. Requirement of molybdenum sputtering target purity is strict that it is always above 99.95%. Surface condition surface can be supplied in a shiny, bright or as-rolled condition, dependent upon thickness. Shapes: Shapes of molybdenum sputtering target can be round, rectangle and tube. The regular process of molybdenum sputtering target is sintering, forging, tooling and grounding. [caption id="attachment_439" align="aligncenter" width="400"] Molybdenu... ...Read More>>

Pure Molybdenum and Molybdenum Alloy

2013 年 8 月 9 日 by Elva

Well, today, I get a good artical from the book which mainly introduce the differences between pure molybdenum, TZM alloy(titanium-zirconium-molybdenum), MHC alloy(molybdenum-hafnium-carbon), MLa alloy(molybdenum-lanthanum-alloy), MY alloy(molybdenum-yttrium-alloy), MW alloy(molybdenum-tungsten-alloy), MCu alloy(molybdenum-copper-alloy) in its content, properties and applications. By reading, I have a better understanding in their about them. Here, I am glad to share it with you. Content: Name Ingredients (%) W Ti Zr C La2O3 Y2O3 Hf Cu Mo TZM 0.40~0.55 0.06~0.12 0.01~0.04 0.... ...Read More>>

TZM Alloy&TZC Alloy

2013 年 8 月 7 日 by Elva

Today，my colleague Sarah catches a calling from a costomer who want TZC alloy products. We suggest him to take its place by TZM alloy for they have many similar properties and it is easier to be processed than TZC alloy. Now, let me have an brief introduction of TZM alloy as follows: TZM alloy is also called TZM molybdenum base alloy, molybdenum alloy TZM, molybdenum TZM, molybdenum high temperature TZM, titanium-zirconium- molybdenum. TZM Alloy Chemical Formula: Mo + 0.40-0.55% Ti + 0.06-.012% Zr + 0.01-0.04% C [caption id="attachment_526" align="aligncenter" width="240"] T... ...Read More>>
