Product Description

Alumina Seal Ceramic Rings / Industry Insulation Ceramic Parts

 

1. Description:

Alumina seal ceramic rings / industry insulation ceramic parts  have a excellent properties for chemical and physical stability as belows:
Thermal properties: High heat resistance and high thermal conductivity...
Mechanical properties: High strength and high hardness...
Other properties: High electrical insulation, high corrosion resistance..
99% Alumina ceramic is used to make high-temperature crucible, furnace tube and special wear-resistant materials, such as ceramic bearing, ceramic seal and water valve sheet, etc.
95% alumina ceramic is mainly used as corrosion-resistant and wear-resistant parts.Due to the addition of talc, the electrical properties and mechanical strength are improved, which can be sealed with molybdenum, niobium, tantalum and other metals, and some are used as electrical vacuum devices.
