What Are The Alternatives To Using Sodium Tungstate In Industry?

There are several alternatives to using sodium tungstate in industry, including:

1. Ammonium paratungstate (APT): APT is a commonly used alternative to sodium tungstate for the production of tungsten metal and alloys. It is produced by dissolving tungsten ore in ammonium hydroxide solution, which forms a white crystalline salt that can be further processed.

2. Tungsten oxide: Tungsten oxide is another alternative to sodium tungstate that is used in the production of tungsten metal and alloys. It is typically produced by roasting tungsten concentrate at high temperatures, which converts the tungsten into tungsten trioxide.

3. Tungsten carbide: Tungsten carbide is a compound of tungsten and carbon that is widely used in cutting tools and other industrial applications. It is made by reacting tungsten oxide with carbon at high temperatures.

4. Tungsten disulfide: Tungsten disulfide is a low-friction material that is used as a lubricant in a variety of industrial applications. It is produced by reacting tungsten metal with sulfur at high temperatures.

Overall, these alternatives offer similar properties and performance to sodium tungstate, while reducing the environmental impact and cost of production.
