Alumina Ceramics:

Because of its high temperature insulation, it is used as a ferrule tube and protection tube for thermocouples. The insulation used in the atomic reactor is still excellent, and the loss is not large, and the dielectric constant is not large. It is widely used in the electronics industry. Solid integrated electric furnace substrate tube holder, outer casing, porcelain frame, micro-thin window, missile radar antenna protection cover, etc. Alumina is an ionic crystal with a stable structure. Used in high frequency, high voltage and high temperature, its insulation is still excellent, and the loss is not large, the dielectric constant is not large. It is widely used in the electronics industry for solid extruded circuit board bases, casings and porcelain. Shelf, micro glass window, missile radar antenna cover, etc. Alumina ceramic products have good air tightness and are tightly airtight even at high temperatures, so they are widely used in electric vacuum, such as aluminum oxide ceramics for making various large electronic tube shells and dual in-line packages in solid microcircuits. shell. Alumina ceramic insulation materials are widely used in furnace walls and furnace roofs of various high-temperature furnaces, which are resistant to high temperatures and heat.

High hardness, high strength, wear resistance, corrosion resistance, high temperacture (1600°), good thermal diffusivity, good insulativity, low cost etc.
