Lightweight Clay Bricks Description
Lightweight Clay Bricks are made of refractory clay with Al2O3 content of 30%~48%.Using refractory clay, cenosphere, and refractory clay clinker as raw materials, adding binders and sawdust, after batching, mixing, molding, drying and firing.
Lightweight Clay Bricks Features
low density, high porosity, and low thermal conductivity.good thermal insulation performance.,Refractory category allow direct contact of fire.
Light Weight Clay
bricks Application
It is used as thermal insulation material for various industrial kilns and high-temperature environment to reduce heat loss and save energy.
