Main Chemical Components of Refractory Bricks: Alumina

Loka Refractories - You must be familiar with fire bricks or fire clay bricks right? Refractory bricks consist of many components in their raw materials.


However, the main components are alumina and silica. In this article, we will discuss about alumina.


What is alumina? Why is the chemical component alumina used in the manufacture of refractory materials, one of which is refractory brick? Check out the following explanation!


What is alumina?


Alumina is a chemical compound with the chemical formula Al2O3, which is composed of aluminum and oxygen. Not only in the refractory industry, alumina is also widely used in the ceramics and glass industries.


Where does alumina come from?


The natural alumina component is obtained from bauxite, a material in the form of sedimentary rock. In Indonesia, several bauxite producing regions are Sumatra, Riau and Kalimantan.


Bauxite will be processed into calcined alumina which is artificial alumina through the bayer process. Not only calcined alumina, artificial alumina includes fused alumina and tabular alumina.


Why does alumina used for fire bricks?


Not only refractory, alumina is a component of most refractory materials. Why? Because alumina has a high melting point, is a good heat insulator, and withstands high temperature stress.


How to get alumina fire bricks?


Loka Refractories provides refractory bricks with various levels of alumina! Those with high alumina content include SK-36 and SK-38 high alumina bricks. Get high alumina refractory bricks at special prices now!
