Advantages and applications of alumina ceramic insulators

Aluminais widely used in ceramic insulators, insulating porcelain bottles, insulating shells, insulating rods, and other products and accessories used in high and low voltage, AC and DC operations due to its excellent electrical insulation properties, high hardness and good wear resistance. 

Alumina Ceramic Insulators

Alumina Ceramic Insulator Description :

Alumina is the most cost-effective and widely used material in the engineering ceramic family. The raw materials used to make this high-performance technical-grade ceramic are readily available and affordable, and therefore have good cost value when making alumina shapes. With its excellent properties and attractive price, it is no surprise that fine-grained technical alumina is used in a wide range of applications.

Different purities of alumina or alumina (Al2O3) are more commonly used than any other advanced ceramic material. Mingrui Ceramics offers a variety of material types with different properties that can be adjusted by target matrix design.

This material has very high hardness, very high stiffness, very good resistance to high temperature chemicals and very high refractoriness or service temperature.

Applications of alumina advanced ceramics include heavy-duty forming tools in the electronics industry, substrates and resistor cores, ceramic tiles for wear and ballistics, threaded conduits in textile engineering, sealing and regulating discs for valves, radiators for lighting systems, chemical Protective tubes in industrial heat treatment or catalyst supports.
