Refractory material is any material that has an unusually high melting point and that maintains its structural properties at very high temperatures. Composed principally of ceramics, refractories are employed in great quantities in the metallurgical, glassmaking, and ceramics industries, where they are formed into a variety of shapes to line the interiors of furnaces, kilns, and other devices that process materials at high temperatures..
The purpose of a refractory material is to withstand the high temperatures required in furnaces, kilns, incinerators, power plants etc. without contaminating other materials and to conserve heat in the area where it is needed, thus preventing heat loss. Dense refractories are heavy with low porosity but high mechanical strength. Insulating refractories have a higher porosity making them less dense and with low thermal conductivity. This increases efficiency and reduces the amount of energy required for the process at hand.
Below is a list of the most common refractory materials:
1. High-Temperature 90% Alumina Refractory Castables Cement (Service Temperature 1750-1810 degrees)- MAXHEAT A
