What Are The Characteristics Of Alumina Ceramics Used?

1, due to high temperature resistance, corrosion resistance, high strength and other properties, it is used as pouring steel sliding nozzle, smelting rare metal, special alloy, high purity metal, glass drawing crucible and utensils.

A variety of high temperature furnace, such as refractory materials, ceramics, iron blast furnace lining (wall and pipe); Physical and chemical utensils, spark plug, heat and oxidation resistant coating.

2, due to the characteristics of high hardness, good wear resistance, high strength, in the chemical system, used as a variety of reaction vessels and pipes, chemical pump parts.

For mechanical parts, various molds, such as drawing die, extrusion pencil lead die mouth, etc.; For cutting tools, abrasives, bulletproof materials, human joints, sealing grinding ring, etc.

3, because of high temperature insulation, it is used as a thermocouple sleeve tube and protective tube, atomic reactor used in the insulation is still excellent, coupled with small loss, dielectric constant is not large.

It is widely used in the electronics industry for solid state integrated electric furnace base plate tube seat, shell, porcelain frame, thin window, missile radar antenna protective cover, etc.

4, alumina is an ionic crystal, the structure is very stable. In high frequency, high voltage and high temperature use, its insulation is still excellent, coupled with small loss, dielectric constant is not large.
