Alumina Ceramic Honeycomb Description 

Alumina Ceramic HoneycombAlumina Ceramic Honeycomb is made of alumina ceramic. Alumina is a ceramic material with high thermal conductivity, compressive strength, and thermal shock resistance. It also has a low thermal expansion, making it also a suitable material for furnace use in the crucible, tube, and thermocouple sheath form. Honeycomb ceramic is a new type of ceramic product with a structure similar to a honeycomb shape. It is widely used in chemical, electric power, metallurgy, petroleum, electronic appliances, machinery and other industries.
