Refractory high temperature resistance alumina ceramic disc
1. Description
Alumina is the most cost effective and widely used material in the family of engineering ceramics. The raw materials from which this high performance technical grade ceramic is made are readily available and reasonably priced, resulting in good value for the cost in fabricated alumina shapes. With an excellent combination of properties and an attractive price, it is no surprise that fine grain technical grade alumina has a very wide range of applications.
This alumina ceramic heating disc is used for heating in high temperature kiln, it can work at 1300℃.Many heating tube will go through the plate and bind together.
