1. Description
This alumina ceramic disc is used for heating in high temperature kiln, it can work at 1400℃.Commonly customer will use heating wire with the alumina ceramic disc, and then heat in kiln,
Alumina ceramic is widely used in heating application, because alumina ceramic has many advantages such as high temperature resistance, high wear resistance.We take its advantages of high temperature resistance , and apply it into many industry. It can be used for long time. Also it is economic material.
We can customize according customer's drawing.
