    High Hardness Low Density Alumina Ceramic Plate 1650C 1680C

    High Hardness Low Density Alumina Ceramic Plate


    Description:


    The alumina plate is made of aluminum oxide ceramics. Alumina is a ceramic material with high thermal conductivity, compressive strength, and thermal shock resistance. It also has a low thermal expansion, making it a suitable material for furnace use in the crucible, tube, and thermocouple sheath form. Aluminum oxide ceramic plates can withstand high temperature and maintain high strength and hardness.
