Product Introduction
Alumina Bubble Brick is a brick made of alumina hollow spheres as the main raw material, high-performance alumina ultrafine powder as an additive, organic materials as a binder, and dried and formed.
Features
1.High Service Temperature. 2.High Purity. 3.Low Thermal Conductivity. 4.Low Bulk Density. 5.High Mechanical Strength.
Application
Alumina Bubble Brick can be used in high-temperature shaft kilns, shuttle kilns, induction furnaces, nitriding furnaces, etc., and also can be used for service linings in manufacturing high-purity quartz for the electronics industry such as ceramic tile linings in gas turbines and backup linings in reactors.
