Refractory high temperature resistance alumina ceramic disc
This alumina ceramic disc is used for heating in high temperature
kiln, it can work at 1300℃.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.
