What is Subnanometer Violet Tungsten Oxide?

Subnanometer purple tungsten oxide is a transition metal compound material whose average particle size is smaller than that of nanometer purple tungsten oxide. Compared with other tungsten oxides, the crystal structure of sub-nanometer purple tungsten oxide is more special. There are not only abundant cracks inside the particles, but also the shape is basically needle-like or rod-like, which makes the material have a larger porosity, High chemical activity, low bulk density, etc., are more suitable as raw materials for the production of ultra-fine tungsten powder and ultra-fine tungsten carbide powder. Subnanometer violet tungsten oxide is a material of very high purity. Under normal circumstances, its purity can reach 99.95% (3.5N), 99.99% (4N); if the production conditions and raw materials are more reasonably controlled, the purity of purple tungsten oxide can even reach 99.9995% (5.5N). However, not all products are made of high-purity purple tungsten, and the quality will be better. Normally, the purity of purple tungsten oxide should be selected according to the actual production situation.
