5 FAQs of Refractory High Purity Engineering Technical Alumina Ceramic Board Plate Block

Refractory High Purity Alumina Ceramic Boards: Key Questions Answered

What is this alumina ceramic board?
This board is a special ceramic plate. It’s made from very pure aluminum oxide powder. Workers press this powder into shape. Then they fire it at extremely high heat. The result is a hard, dense plate. It handles intense heat well. It resists chemical attack. It stays stable under tough conditions. This makes it perfect for furnaces, kilns, and high-tech equipment.

How hot can it handle?
These boards tolerate very high temperatures. They work reliably for long periods up to 1650°C (3000°F). Some special grades go even higher. They won’t melt or soften at these heats. They keep their shape and strength. But sudden big temperature changes can cause cracking. Heat them up and cool them down slowly.

Is it strong?
Yes, it’s very strong under pressure. It resists squashing forces extremely well. Its hardness is near the top of the scale. It wears down slowly. But it’s different from metal. It can be brittle. It doesn’t bend like stainless steel. It can break if hit hard or dropped. Handle it carefully. Support it properly during use.

How smooth is the surface?
The surface finish varies. We offer different options. Standard boards have a ground finish. This feels slightly rough. The roughness (Ra) is around 1.6 to 3.2 microns. We also provide polished finishes. These are much smoother. Polished surfaces can be below 0.8 microns Ra. Smoother finishes usually cost more. Choose based on your application needs.

How do I clean it?
Cleaning is usually simple. Use a soft cloth or sponge. Plain water works fine. For tougher dirt, use a mild soap solution. Avoid harsh chemicals. Don’t use strong acids or alkalis. They can damage the surface over time. Rinse thoroughly with clean water after cleaning. Dry it with a soft cloth.
