Violet tungsten is tungsten oxide. Tungsten has the most special crystal structure (needle or rod) and is an important raw material for the production of ultrafine tungsten powder. Its chemical formula is W18O49 or WO2.72, and its molecular weight is 227.36.
Violet tungsten has a phase composition of WO2.72 (or W18O49). Because of its unique crystal structure, it has superior performance when used to prepare fine tungsten powder and fine tungsten carbide powder, and it will soon be used in production.
