5 FAQs of Refractory Insulation 99% Alumina Aluminum Oxide Ceramic Disc Disk Dish

Here are 5 FAQs about the Refractory Insulation 99% Alumina Aluminum Oxide Ceramic Disc:

What is this ceramic disc?
It’s a disc made from 99% pure aluminum oxide (alumina). This material handles extreme heat. It provides excellent thermal insulation. It resists very high temperatures without melting.

How hot can it get?
This alumina disc withstands constant temperatures up to 1700°C (3092°F). Short bursts can reach even higher. This makes it suitable for furnaces, kilns, and high-heat industrial processes. It won’t degrade easily under intense heat.

Why is thickness important?
Thickness directly affects performance. Thicker discs offer better insulation. They handle thermal stress better. Thin discs heat faster. They also break easier under sudden temperature changes. Choose thickness based on your specific heat needs and mechanical stress.

Is it fragile?
Yes, alumina ceramic is very hard. It’s also brittle. Handle it carefully. Avoid impacts or drops. It cracks easily under mechanical shock. Protect the edges during installation. Use proper mounting techniques. Never force it into place.

What sizes are available?
These discs come in various diameters. Common sizes range from small (like 10mm) to large (over 200mm). Thickness options vary too. Standard thicknesses are often between 1mm and 10mm. Custom sizes are usually possible. Check with the supplier for exact dimensions.
