Tungsten powder, tungsten powder, is the raw material for preparing tungsten processing materials, tungsten alloys and tungsten products. It is a gray black metal with a metallic luster (BCC crystal). The hardness of tungsten is the hardest part of metal. The hardness of sintered tungsten bar is 200~250, and the tungsten rod of rotary hammer is 350~400. Mixed acid dissolved in nitric acid and hydrofluoric acid. The mixture is fused with a mixture of sodium hydroxide and sodium carbonate. It is slightly soluble in nitric acid, sulfuric acid and aqua regia. It is insoluble in water, hydrofluoric acid and potassium hydroxide. Tungsten has two types of variants, a and B. Under normal temperature and normal pressure, A-type is a stable body centered cubic structure. Type B tungsten can only occur under aerobic conditions. It is stable below 630 C and converted to a tungsten at more than 630 C, and the process is irreversible.
