Product introduction:

Silica pebbles are mined in mines. It has the characteristics of high silicon, low iron, high density, wear resistance, smooth surface. It is a high-quality grinding medium. Silica pebbles have three different grades: Grade A, Grade B, and Grade C, respectively.

SiO2, as the main component of silica pebbles, is an indispensable raw material in ceramic production. This has an important impact on the properties and quality of ceramics.

First, the silica content determines the hardness and compressive strength of the ceramic. When making ceramics, the appropriate addition of silica can increase the hardness and stability of the ceramic body, so that the ceramic has better wear resistance and durability.

Secondly, the content of silica will also affect the fineness and texture of the ceramic. A higher content of silica can improve the sintering temperature and sintering density of ceramics, making the porcelain body more dense and uniform, thus showing a more delicate texture and surface quality.

In addition, the silica content will directly affect the whiteness and light transmittance of ceramics. For the production of white porcelain and transparent porcelain, it is necessary to use a high silica content to make the porcelain body appear white and bright and have good light transmission.
