Tungsten oxide

Blue tungsten oxide which shorted for BTO, yellow tungsten oxide which shorted for YTO, violet tungsten oxide which is shorted for called VTO and tungsten dioxide are all called tungsten oxide. Blue tungsten oxide and yellow tungsten oxide are more regular products than violet tungsten oxide and tungsten dioxide. Because the chemical formula of yellow tungsten oxide is WO3, it also is called tungsten trioxide. Therefore, when people say tungsten 2021-03-12 Tungsten oxide is an inorganic chemical compound. It incluldes tungstic acid (H2WO4), yellow tungsten oxide (YTO, WO3), blue tungsten oxide (BTO, WO2.9), violet tungsten oxide (VTO, WO2.72or W18O49), brown tungsten oxide (tungsten dioxide, WO2) and cesium tungsten bronze (Cs0.33WO3). Micron grade tungsten oxides are mainly used as the raw material Tungsten oxide also called tungsten trioxide, including yellow tungsten oxide (YTO, WO3), blue tungsten oxide (BTO, WO2.9), violet tungsten oxide (VTO, WO2.72or W18O49) and brown tungsten oxide (tungsten dioxide, WO2).
