5 FAQs of 1500-1800C High Temperature Industrial Big Crucible 99 Alumina Square Ceramic Crucible Ceramic Alumina Boat Crucible

What exactly is this crucible?
This is a specialized container made for industrial heat processes. It holds materials during high-temperature work. The crucible is square-shaped. It is constructed from 99% pure alumina ceramic. Alumina ceramic is a very hard, dense material. It withstands extreme conditions well. People call it an alumina boat crucible due to its shape.

How hot can it get?
This crucible handles very high temperatures. Its maximum continuous use range is 1500°C to 1800°C. It is built for intense industrial furnace applications. Short bursts might go slightly higher. Always check the specific manufacturer’s rating. Do not exceed the recommended limit.

Why use 99% alumina?
High purity alumina is key. It offers superior resistance to heat and chemicals. 99% alumina means minimal impurities. Impurities weaken the ceramic at high heat. This purity ensures stability. It prevents cracking or contamination. It lasts much longer than lower-grade ceramics.

What’s the benefit of the square shape?
The square boat design is practical. It fits efficiently inside many furnace types. It maximizes usable space on a shelf. It allows stable stacking of multiple crucibles. The shape helps contain powders or small parts. It often provides a larger flat surface area than round versions.

How should I handle it?
Handle alumina ceramic crucibles carefully. They are strong but can chip if impacted. Avoid sudden temperature changes. Thermal shock can crack them. Heat and cool furnaces slowly. Use proper tongs suited for high temperatures. Clean gently after use. Inspect for cracks before each use. Replace damaged crucibles.
