Mirror Polished High Precision Alumina Oxide Ceramic Tube
Aluminum oxide (Alumina) has an extensive application due to its versatility and low cost of material than other advanced ceramics. Alumina offers high electrical insulation resistance, high-temperature resistance, strong hardness, wear resistance, and good chemical stability, making it a good material to withstand high temperature and chemical corrosion.
Alumina Oxide Ceramic Tube is suitable for all kinds of laboratory metal and nonmetal sample analysis and melting materials. Corundum tube is mainly used in high temperature vacuum tube furnace, vacuum furnace atmosphere, tin groove tube float glass industry, solar glass in protecting tube, electric stove wire supporting tube, aluminum trichloride industry chlorine pipe, muffle furnace tube, etc.
