99.99% tungsten trioxide is a yellow powder that can show different crystal structures at different temperatures. It is mainly applied in the following fields:
1. To prepare tungsten powder and its downstream products, such as tungsten metal products (tungsten wire, tungsten electrode, etc.) and tungsten carbide materials (knives, molds, etc.).
2. As a catalyst, for a variety of organic synthesis.
3. Used as a colorant in high temperature transparent material, dielectric and piezoelectric ceramic, high-grade ceramic and the ion-coating activator for powder coating.
4. Used for the X-ray screen and the plate glass of color picture tube.
5. Used as fire-proof fabric and flame-retardant high polymer material.
6. In recent years, it can be used as an electrode material for various types of novel color display with electrochromic performance.
With the continuous expending and deepening of tungsten trioxide, it not only requires the improvement of chemical index of tungsten trioxide, but also puts forward the requirements of main physical properties of the tungsten trioxide - particle size. It means more multiple specifications.
