Titanium tungsten powder is also known as the anatase titanium dioxide with tungsten oxide, is a kind of white insoluble powder, the crystal structure is the sharp titanium type, belongs to a relatively safe new material. Characteristic At 350°C, titanium tungsten powder is transformed from amorphous crystal to anatase; At 600°C, it is transformed from anatase to rutile; At 750°C, it is completely transformed into rutile type. In nature, there are three kinds of crystal types, such as anatase, titanium…

The wide size tungsten powder is used for sintering and other requirements of tungsten powder. The grade is relatively low, and the density of tungsten powder is relatively cheap, which is far lower than the high-purity tungsten powder. Appearance The color is silver gray, the particle size is not uniform, the surface is not obvious impurities, the powder shape is irregular shape. Characteristic Low grade, good looseness and solid density. Its looseness and density will increase with the increase of…
