Alumina Ceramic Ball Valve Corrosion-Resistant Solutions for Chemical Industry

Product Description

Product Description

Product Introduction:
Alumina wear-resistant ceramic product is a new ceramic chemical material with low wear, high specific gravity and high hardness. mainly made of aluminum oxide (AL2O3) and sintered at a high temperature of 1700°C.

Feafure:
1.Good strength and stiffness               
2.Extremely high hardness
3.Exceptional resistance to wear            
4.Good corrosion resistance to acid and alkali
5.High temperature resistance up to 1750ºC  
6.Excellent electrical insulation
7.Low dielectric constant and dielectric loss

Applications:
Alumina ceramic products are suitable for use in mechanical equipment that needs protection from abrasion, as well as in systems for material delivery, pulverizing, ash or dust cleaning in thermal power production, and other applications. They are also suitable for various high-voltage and high-current applications.
