Product introduction:

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

First of all, the content of Fe203 of flint pebbles as grinding media will affect the color of ceramic products. In the production of ceramic products, low levels of iron oxide can give the ceramic products a light yellow or light red color. But ceramic products may appear dark red, brown, or even black if the Fe2O3 of flint pebbles is high. 

Secondly, the content of Fe203 of flint pebbles as grinding media can also affect the hardness and toughness of ceramic products. The proper content of iron oxide can improve the hardness and wear resistance of porcelain, and enhance its compressive strength and durability. If the iron oxide content is too high, it may cause the ceramic products to become fragile or wear-resistant. 

In addition, the content of Fe203 of flint pebbles as grinding media can also affect the chemical and physical properties of ceramic products. Low levels of iron oxide can promote the solidification of porcelain, improve its physical properties, and enhance its anti-aging ability and water resistance. However, excessive levels of Fe2O3 may lead to increased brittleness and permeability of ceramic products.
