5 FAQs of High Working Temperature 99% Alumina Ceramic Plate Crucible Cover Crucible Lid

Here are five common questions about our high working temperature 99% alumina ceramic crucible covers. These lids are vital for lab work requiring extreme heat. People often ask what they are made of. The answer is simple. The main material is alumina, specifically 99% pure aluminum oxide. This purity gives the lid its special high-temperature strength and chemical resistance. It is very different from lower purity ceramics.

Another big question is about temperature limits. How hot can these lids really get? They perform well continuously at temperatures reaching 1700°C. Short bursts might push higher. This makes them suitable for demanding furnace applications. It is crucial not to exceed the recommended limits. Doing so risks damaging the lid.

People also want to know typical uses. Where would you use such a cover? These alumina lids are common in research labs and industrial settings. They cover crucibles holding molten metals or processing special ceramics. They are also used in high-temperature chemical synthesis. Their job is protecting the crucible contents from contamination and heat loss.

Handling is another concern. Are these lids fragile? Yes, like most ceramics, they can break if dropped or hit hard. Care is needed when moving them. Always use proper tools like ceramic tongs. Avoid sudden temperature changes. Placing a hot lid on a cold surface can cause cracks. Thermal shock is a real risk.

Finally, users ask about cleaning. How do you clean a used alumina crucible lid? The process is straightforward. Let the lid cool down completely first. Then, soak it in a mild cleaning solution if needed. Often, warm water and a soft brush work fine. Avoid harsh chemicals or abrasive scrubbing. These can damage the smooth surface. Proper cleaning ensures long lid life.
