Loka Refractories - Are you curious about what refractory bricks are made of? One of the main raw materials is silica.

In a previous article, we discussed one of the raw materials of fire bricks, which is alumina.

Another main component of fire bricks is silica. Therefore, fire bricks are also called aluminosilicate bricks.

So, what is silica and why is it one of the main raw materials not only for fire bricks but also for most other refractory materials?

What is silica?

Silica is one of the aggregate raw materials for refractory such as fire bricks, mortars, and others.

Having a chemical formula of SiO2, silica is a raw material that is easily obtained and therefore, inexpensive.

Where is silica obtained from?

There are two natural sources of silica, which are quartz and diatomaceous soil that has been calcined.

Natural quartz sand or silica sand comes from the beach, sand clay, or crushed sandstone.

Diatomaceous soil contains silica shells from diatoms (a type of single-celled algae).

Silica is one of the main raw materials for refractory because it is easily obtained and has insulating properties or can withstand heat.
