The advantages of industrial grade lithium carbonate in glass manufacturing
1、 Reduce production costs and improve efficiency
Significant melting aid effect
Industrial grade lithium carbonate can effectively reduce the melting temperature of glass raw materials (about 723 ℃), reduce high-temperature energy consumption, shorten melting time, and improve production efficiency.
Its weak alkaline properties react with acidic raw materials to produce silicate and other components, promoting uniform mixing of raw materials and reducing bubbles and crystallization defects.
Lower raw material costs
Compared to battery grade lithium carbonate, industrial grade products have lower purity requirements (usually ≥ 99%), simplified preparation processes, and reduced raw material costs by about 20% -30%, making them suitable for large-scale glass production needs.
2、 Improve glass performance
Enhance transparency and heat resistance
Lithium carbonate improves the transmittance and refractive index by optimizing the glass network structure, making it particularly suitable for optical glass manufacturing.
Its addition can significantly improve the high temperature resistance of glass (such as enhancing the heat resistance of high-strength glass), making it suitable for building or industrial glass14 in high-temperature environments.
Enhance mechanical strength and chemical stability
Industrial grade lithium carbonate enhances glass hardness and impact resistance by generating aluminum salts and other components, reducing the risk of external damage.
Reduce the sensitivity of glass surface corrosion and extend its service life, suitable for glass products in chemical equipment or corrosive environments.
