Hydrogen reduction of chlorides is a perspective recovery process for refractory metal and alloy scraps.
用氯化物氢还原法从废料中回收高熔点金属和合金具有良好未前景。
And refractory metal gate is considered to be the most promising candidate.
而难熔金属栅则被认为是最有希望的替代者。
The main measurement to improve its properties is to add something to the nickel-aluminum system, such as metallic molybdenum, nickel-boron and refractory metal silicates.
目前主要的改善方法是向铝包镍中添加元素,例如:添加金属钼、镍硼粉和难熔金属硅化物等。
In particular, when the refractory metal silicide film is a tungsten silicide film, the concentration of cu is preferable that it is in the range of 0.1 to 1.0 wt. %.
特别是,当难熔金属硅化物薄膜是硅化物薄膜的钨,铜的浓度最好,它在0.1至1.0范围为野生。%。
C/C composites with refractory metal compounds were prepared by liquid impregnation, the distribution state of refractory metal grain was observed by optical microscope and surface scan.
Some major refractory metal (W and Mo) manufacturers, main products, processing techniques and facilities in former USSR are introduced. A preliminary evaluation is also given in this paper.
