Product Information
Name:
Sodium metatungstate hydrate
Synonyms:
- Sodium polytungstatehydrate
Description:
Sodium metatungstate hydrate is a mineral additive that is used in the production of glass, ceramics, and enamel. It is used to increase the thermal expansion of glass and ceramic products by adding it to the melt before pouring into molds. It also acts as a buffer, reducing the hydrochloric acid content in molten glass. Sodium metatungstate hydrate can be prepared by heating tungsten trioxide with sodium carbonate or sodium hydroxide. The reaction time and detection time depend on how much water is present in the mixture.
