The melting point of oxide ceramics is mostly above 2000 ° C, and the firing temperature is about 1800 ° C; its strength decreases with increasing temperature, and pure oxide ceramics will not oxidize at any high temperature.

Alumina tube ceramic is a widely used product. Its main component is alumina, which has a melting point up to 2050 ° C. It has good oxidation resistance and is widely used in refractory materials. High purity alumina powder is pressed and formed at high temperature to obtain corundum refractory Bricks, crucibles, electric furnace tubes, thermowells, etc.
Of course, alumina-based products also include alumina insulation tiles, alumina insulation bases, alumina insulation gaskets, and so on. We make the following introduction to the characteristics of our company‘s alumina tube products:
