Embodiment 1
[0019] In this embodiment, the preparation method of the alloy element and rare earth oxide doped tungsten-based composite material is as follows:
[0020] Step 1: Preparation of precursor powder
[0021] A certain amount of yttrium nitrate hexahydrate (Y(NO 3 ) 3 ·6H 2 O, Aladdin, purity ≥ 99.9%), ammonium rhenate (NH 4 ReO 4 , purity ≥ 99.9%) and surfactant triethanolamine oleate (C 16 h 22 N 4 o 3 , purity ≥ 99%) were dissolved in a certain amount of deionized water, and then the three solutions were mixed and stirred evenly; then added ammonium metatungstate (AMT, Aladdin, purity ≥ 99.95%) solution dissolved in a certain amount of deionized water Then put it into a magnetic stirrer to heat and stir well, and finally add a certain amount of oxalic acid dihydrate (C 2 h 2 o 4 2H 2 O, analytically pure) as a precipitant, the mixed solution was heated at a constant temperature in a magnetic stirrer at 120°C to evaporate the liquid, and then put into an oven for dry...
