The spherical tungsten powder was fabricated by spray-drying method combined with hydrogen reduction using ammonium metatungstate (AMT) as raw materials.
以偏钨酸铵(AMT)为原料，采用喷雾干燥法结合氢气还原方法成功制备出球形钨粉。
Nanometer tungsten nitride powders were synthesized as amm onium metatungstate by means of spray drying, calcination, milling and nitration in pure ammonia.
