Ceramic Plate
1200–1800°C
Main applications
ceramic plate for the hottest points
Key Features
Extreme heat resistance above 1200°C
Sintered ceramic plate — insulation and dielectric performance beyond the limits of organic and other inorganic materials
Dielectric performance at temperature
The high-temperature insulating character of ceramics — ideal for electric furnaces and heater insulation
High mechanical strength
The hardness and compressive strength of sintered ceramics — holding form under mechanical shock and load
Oxidation and slag resistance
Properties remain stable in oxidising atmospheres and on contact with slag
Precision machinable
Machined with CNC and diamond tooling — custom-shaped insulating components can be made
