Product Description:

Acid Resistant Brick

CMAX  firebricks are classified under temperature between 1300℃ to 1700℃, manufactured from high purity alumina clay.

High alumina refractory brick is dense shaped refractory material. With high refractoriness and mechanical behavior under high temperature, refractory brick is the necessary material of high-temperature services, mainly used for industrial furnaces and kilns and thermal equipment.

High alumina refractory brick has wide applications, mainly used in metallurgy, construction(cement and glass), petroleum, chemical industry, electric power and machine building.

Fire Clay Refractory Brick


1.High plasticity
2.Good thermal shock performance 
3.Hardening quickly
4.Low price    


The product is a specialty produced from the sedimentary clay in Guangxi, with fine particle size, viscosity, high plasticity, combined with strength, good dispersing and high refractoriness advantages.

The mineral composition is mainly disordered Kaolinite >65% of, quartz <30%, Montmorillonite <10%,Illite<3%,and a small amount of Titanium minerals such as Iron.

The mineral’s particles are fine, the Kaolin particle size is less than 2μm.The clay has high plasticity, plasticity index typically greater than 25,some up to 45 above.
