Glass Grade Barium Carbonate

Description

Glass Grade Barium Carbonate (BaCO3) is a white crystalline powder that is odorless, tasteless, insoluble in water, but soluble in acidic solutions. The compound occurs naturally in the form of quartz, limestone, and pyrite. In industrial production, barium carbonate is usually produced by chemical reactions or extracted from ores1.

Role of barium carbonate in glassmaking:

Lowering the melting temperature.
In glassmaking, barium carbonate acts as a catalyst, lowering the melting temperature of glass. Normally, glassmaking requires high-temperature melting and then cooling to form. The addition of barium carbonate can lower this melting temperature, making the production process more efficient1.

Improving optical properties:
Barium carbonate can also improve the optical properties of glass, making it more transparent, and increasing the hardness and wear resistance of glass.

Improving durability and stability:
In the manufacture of flat glass, Glass Grade Barium Carbonate is use as a stabilizer and then can improve the durability and stability of glass1.

Ensuring high purity and transparency:
In the manufacture of optical glass, materials of particularly high purity are required. The addition of barium carbonate helps remove impurities from glass, ensuring the high purity and transparency of optical glass1.

Improved stability:
When manufacturing pharmaceutical glass containers, the addition of barium carbonate can improve the stability of glass and ensure the safe storage of medicines1.

Uses of barium carbonate in glass manufacturing:

Flat glass:
In the manufacture of flat glass, barium carbonate is use as a stabilizer to improve the durability and stability of glass1.

Optical glass:
