Feature of alumina ceramics:

1.Alumina ceramic ring has excellent mechanical strength, high temperature resistance, wear resistance, corrosion resistance, good insulation performance, durable. It has the advantages of long life, energy saving, environmental protection, safety and controllability.

2.It has excellent electrical function at high frequency, and its medium loss is small, volume resistivity is large, strength is high, hardness is high, linear expansion coefficient is small, and wear resistance and heat resistance are also good. It is more economical and practical to use 95% alumina ceramics in general occasions. On the occasion of particularly high functional requirements, 99% ~ 99.9% alumina porcelain is selected.

Advantages of alumina ceramics:

1.Dimensional and thermal stability, high performance characteristics, hydrolysis resistance, self-lubrication, extended service life, reduced downtime and cost, low moisture content, noise reduction

Application of alumina ceramic ring:
1. Chemical industry:
Due to the corrosion resistance and high temperature stability of alumina ceramic rings, it is often used as the lining material of reactors, pipelines and containers in the chemical industry to protect equipment from corrosion and high temperatures.
2.Electronic Engineering:
The insulating properties of alumina ceramic ring make it an important part of electronic components, such as insulation bushing, electronic ceramic capacitor, etc.
3.Machinery industry:
The hardness and wear resistance of alumina ceramic rings make them widely used in mechanical fields, such as bearings, bushings, mechanical seals and so on.
4.Mining industry:
Alumina ceramic rings can be used as abrasives and polishing materials in the mining field to improve the processing efficiency and surface finish of ores.
