High Temperature Proof Aluminum Oxide Ceramic Plate Excellent Performance Insulation


Alumina Ceramic plate

1.Product description

The main material of ceramic plate is Aluminium Oxide( Al2O3). The purity varies from 92%-99.7%, density from 3.0-3.96g/cm3, and working temperature from 1000-1800°C. It offers a combination of superior mechanical strength and electrical properties, wear resistance and corrosion resistance.

Specifications:

Diameter & Length:5-850mm


Height:5-850mm

All alumina ceramic plates could be customized according to your data requirements and drawings.
