Electrochemistry substitution precipitation method in order to produce the compound metal powder

摘要

Electrochemistry substitution precipitation method in order to produce the compound metal powder is stated. It does this method, the particle of the tungsten or molybdenum metal by mixing with silver oxide or the particle of copper oxide in the water hydroxide solution. The aforementioned solution is heated the particle of the aforementioned oxide in order to transform to the particle of the silver or copper metal which it glues to the particle of the aforementioned heat-resistant metal substantially. Until recently although the compound metal powder is produced unlike method, it is not necessary to heat the oxide powder to high temperature very under reducing atmosphere.
