Tungsten oxide (WO3) is an important oxide with various physical properties. The following are some common physical properties of tungsten oxide:
Tungsten Oxide Appearance Color
Pure tungsten trioxide usually appears yellow or light yellow, but its color can vary due to crystal structure and particle size.
Tungsten Oxide Density
Tungsten trioxide has a density of approximately 7.16 g/cm³.
Tungsten Oxide Melting Point
Tungsten trioxide has a melting point of about 1,470 °C.
Tungsten Oxide Crystal Structure
The crystal structure of tungsten trioxide includes monoclinic structure (α-WO3) and triclinic structure (β-WO3). α-WO3 is the most common crystal structure form.
Refractive index of tungsten oxide
Tungsten trioxide typically has a refractive index between 1.9 and 2.3, depending on the wavelength and how the sample is prepared.
Tungsten Oxide Conductivity
Tungsten trioxide is generally an insulator, but under certain conditions, such as high temperature or doping, it can exhibit some electrical conductivity.
Tungsten Oxide Thermal Stability
Tungsten trioxide has good thermal stability under high temperature conditions and can be used in high temperature applications.
These are some common physical properties of tungsten trioxide, and the specific properties may vary due to factors such as sample preparation methods, crystal structure forms, impurity doping, and experimental conditions.
