What are the advantages of using boric acid in glass manufacturing?

Boric acid is an important inorganic chemical raw material, typically appearing as a white crystalline powder. It is weakly acidic, readily soluble in water, and decomposes and dehydrates at high temperatures, offering numerous significant advantages in glass manufacturing. It effectively reduces the melting temperature and viscosity of glass, decreasing energy consumption and extending the lifespan of furnace equipment. Furthermore, it serves as a crucial component of the glass network structure, significantly improving the glass's thermal shock resistance, chemical stability, and mechanical strength. In addition, boric acid improves glass clarification, reduces bubbles and inclusions, and enhances transparency and uniformity. Free from toxic substances such as lead, it meets environmental protection requirements and is therefore widely used in the production of various glass products, including high borosilicate glass, optical glass, and heat-resistant glass.
