92% High alumina lining bricks for grinding machine

92% High alumina lining bricks for grinding machine  for applications up to 1800°C/ 3270°F, these brick have excellent insulating properties and high hot strengths. Bubble alumina bricks are made with tiny hollow insulating spheres made from high-purity alumina (also called bubble alumina). Alumina does not exhibit high thermal conductivity, and when in the form of hollow spheres, its thermal conductivity is additionally reduced. Both properties made Bubble Alumina brick an excellent insulating material that can withstand exceptionally high temperatures. Typical applications for Bubble alumina bricks include gas or electrically heated kilns and furnaces as well as glass making industries.

92% High alumina lining bricks for grinding machine  Features:

1. Low thermal conductivity.
