Nano Tungsten trioxide WO3 powder price Cas 1314-35-8
Brief introduction:
Nano tungsten trioxide powder (WO3) is an oxide composed of transition metal tungsten elements and non-metallic oxygen elements. It is a ultrafine yellow powder composed of positive hexavalent tungsten ions (W6+) and negative divalent oxygen ions (O2-). The chemical formula is WO3, the molecular weight is 231.85, and the CAS number is 1314-35-8.
Nano tungsten trioxide is obtained by hydrothermal method, with fine particle size and high purity. Nano tungsten trioxide has the ability to absorb electromagnetic waves and can be used as an excellent solar energy absorbing material and stealth material. Nano tungsten trioxide has a large specific surface area, surface effect, and catalytic performance. As a compound of transition metals, nano tungsten trioxide is a wide bandgap n-type semiconductor with great potential as a material.
