Application of Boric Acid in the Ceramics Industry

In our daily lives, ceramic products are a very important part of our existence and can be seen everywhere. You might ask, what is the relationship between ceramics and boric acid? Below, the boric acid manufacturer will carefully analyze the relationship between the two, hoping to be helpful to everyone.

During the production process, the enamel and ceramic industries use boric acid in glaze production. It can reduce the thermal expansion of the glaze, lower the solidification temperature of the glaze, thereby preventing cracking and glaze peeling, while improving the gloss and durability of the products. For ceramic and enamel glazes, boron oxide (B₂O₃) serves as an excellent flux and network former. It can form glass (at low temperatures), improve the adaptability between the body and the glaze, reduce viscosity and surface tension, increase the refractive index, and enhance mechanical strength, durability, and wear resistance.

This is because boric acid is an important component of lead-free glazes. High-boron frits mature quickly, forming a smooth glaze surface rapidly, which is beneficial for coloring. The boric acid manufacturer points out that in fast-firing glazed tile frits, B₂O₃ is introduced in the form of boric acid to meet low sodium content requirements, thereby ensuring better product quality.
