Tungsten dioxide is a brown monoclinic powder crystal, which is also called brown tungsten because of its tan appearance, similar to chocolate. Tungsten dioxide is mainly used in the manufacture of tungsten powder and tungsten trioxide. Tungsten dioxide is insoluble in water, alkaline solution, hydrochloric acid and dilute sulfuric acid. Tungsten dioxide is produced by hydrogen reduction of tungsten trioxide at 575~600°C. Nitric acid can oxidize tungsten dioxide into high-valent oxides. Tungsten dioxide is quickly oxidized to tungsten trioxide in air, and turns into blue oxide when heated to 500°C in nitrogen oxide. At 1020°C, tungsten dioxide can be reduced to metal tungsten by carbon.
