Violet tungsten oxide physical property refers to characteristics such as appearance, crystalline size, density.
Appearance: Violet fine crystalline powder.
Density: 7.724~7.989 g/cm3
X-ray tested density: 7.78 g/cm3
Crystalline size: 10~18um
Violet tungsten oxide is a form of tungsten oxide, has special crystalline structure. Due to its abundant crack inside of aggregates and needle or rod shape of granule, it thus has big vacancy and results in the lower apparent density. As a result it has special physical and chemical property.
