5 FAQs of High Temperature Resistant Alumina Al2o3 Ceramic Solid Block Brick Plate

What exactly is this alumina ceramic block?
This is a solid piece made from aluminum oxide powder. We compress and fire the powder at very high temperatures. The result is a dense, hard ceramic block. It withstands extreme heat without melting or deforming.

Why is it so good with high temperatures?
Alumina ceramic has a very high melting point, over 2000°C. Its chemical structure stays stable even when hot. It doesn’t easily react with other materials at high heat. This makes it reliable for intense heat applications.

Where would I use this high-temperature brick?
Use it inside furnaces and kilns as linings. It works well as setters and supports for firing other ceramics or metals. It’s good for burner nozzles, heat shields, and thermocouple protection tubes. Any place needing strong, heat-proof material benefits.

Can it handle sudden temperature changes?
Yes, but it depends on the grade. Higher purity alumina generally handles thermal shock better. Thicker sections crack more easily than thinner ones with fast temperature shifts. It’s tough, but avoid very rapid heating or cooling if possible.

What sizes and shapes can I get?
Manufacturers offer standard blocks, bricks, plates in many sizes. Common thicknesses range from a few millimeters up to 100mm or more. Length and width vary significantly. Custom shapes and sizes are often possible, though they cost more.
