Nano Tungsten(IV) Oxide Powder Description
Nano Tungsten(IV) Oxide Powder, also known as brown tungsten oxide, has the chemical formula WO₂ and exists in a powder form with a brown color. It crystallizes in the monoclinic system and is soluble in concentrated sulfuric acid, but insoluble in water, hydrochloric acid, dilute sulfuric acid, and alkaline solutions. It possesses both reducing and oxidizing properties. However, in practical production, tungsten dioxide is not typically produced as a finished product, as it primarily serves as an intermediate in the production of other tungsten compounds.
Like other tungsten oxides, tungsten dioxide can exist in ultra-fine nanoparticle forms, including sub-nanometer particles. Compared to regular tungsten dioxide, sub-nanometer tungsten dioxide exhibits superior physical and chemical properties, making it more suitable for the production of high-grade tungsten compounds, such as tungsten metal powder, tungsten carbide powder, and ultra-fine tungsten trioxide particles.
