Product Description of Barium Silicate CAS#13255-26-0

Barium silicate is an industrial-grade product with a purity of ≥99%. It appears as a white, odorless crystalline powder. The compound has a melting point of 1604℃ and decomposes at high temperatures instead of boiling. It exhibits negligible vapor pressure at 25℃ and has a relative density of 4.35 at 20℃.

This product is insoluble in water, slightly soluble in hydrofluoric acid, and insoluble in hydrochloric acid and nitric acid. It is stable under normal conditions but should be kept away from hydrofluoric acid and other strong acids due to incompatibility.

Product Application of Barium Silicate CAS#13255-26-0

Barium silicate is used to produce films suitable as transmission media in integrated optical circuits. By adjusting the ratio of the target constituents, these films can achieve a wide range of refractive indices while maintaining low optical attenuation, making them ideal for integrated optical circuit applications.

In addition, barium silicate is widely used in the ceramics industry.
