| description | The invention discloses a process for doping tungsten powder with lanthanum and cerium in a dry mode. The process comprises the following steps that S1, the tungsten powder and lanthanum and cerium oxide powder are mixed according to a certain proportion; s2, the mixed powder is crushed, mixed and stirred in a high-energy mixer, and lanthanum-cerium alloy tungsten powder is obtained; s3, the lanthanum-cerium alloy tungsten powder is subjected to follow-up procedures such as screening, pressing and sintering, and a high-performance tungsten rod or tungsten filament is prepared; compared with the prior art, the method has the advantages of simple process, low cost and environmental friendliness by adopting a process of doping lanthanum and cerium in tungsten powder in a dry manner, does not need to use an organic solvent or other chemical reagents, only needs to mix the tungsten powder and the lanthanum cerium oxide powder according to a certain proportion, and then crushes, mixes and stirs in a high-energy mix |
