Product introduction:

Dalian Gaoteng supply high silica content flint pebbles with few iron content as experienced manufacturer.

The content of silica can affect the chemical stability of ceramic products. Ceramic products with high SiO2 content are more waterproof and corrosion-resistant, and are less susceptible to external environmental influences. However, if the content of silicon dioxide in ceramic products is too low. It will cause them to be less resistant to acid and alkali corrosion, and are prone to cracking and damage during use.

Therefore, an appropriate silicon dioxide content is crucial for the quality of ceramic products. It can not only improve their hardness, strength, and wear resistance, but also enhance their chemical stability. Thereby extending the service life of ceramic products.
