Method of controllably reducing oxygen content, and preparing titanium metal powder and Ti6A14V alloy powder

A method of controllably reducing an oxygen content, comprising the following steps:

• (1) mixing a raw material, a calcium source, a first reductant and a first adjuvant, and performing first reduction to obtain a reduced material;
• wherein the raw material is a vanadium oxide or a titanium source, and the first reductant comprises aluminum;
• and
• (2) performing a first wet treatment on the reduced material to obtain a first reduced powder;
• wherein when the raw material is the titanium source, the first reduced powder is TiOx, wherein a value range of x in TiOx is 0.167≤x≤1;
• or when the raw material is the vanadium oxide, the first reduced powder is a VAly alloy, wherein a value range of y is 0.20≤y≤5.80;
• wherein when the raw material is the titanium source, the mixing in step (1) comprises:
• performing first mixing on the titanium source and the calcium source to obtain a calcium-containing titanium source, and performing second mixing on the calcium-containing titanium source, the first reductant and the first adjuvant;
• a molar ratio of calcium in the calcium-containing titanium source to the first reductant is 0.6:1 to 2:1;
• a molar ratio of the first reductant to titanium in the calcium-containing titanium source is 0.67:1 to 1.33:1;
• and
• a mass ratio of the first adjuvant to titanium in the titanium source based on TiO2 is 0.05:1 to 3:1.
