Doped tungsten powder is initial materials made of tungsten products, is tungsten powder doped with a certain amount of K, Si, Al oxide, tungsten powder adding rare earth element can obtain high temperature and room temperature properties are excellent doped tungsten products, used in the production of tungsten bars, tungsten bars, tungsten molybdenum alloy, tungsten alloy, etc. Rare earth elements promote the increase of potassium content in tungsten powder. The addition of rare earth elements can make tungsten oxide reduction…
