5 FAQs of 99% Alumina Ceramic Slabs Plate Sheet

99% Alumina Ceramic Slabs: Top 5 Questions Answered

What’s the highest temperature these slabs handle?
99% alumina ceramic slabs withstand very high heat. They manage continuous use up to 1650°C (3000°F). Short-term exposure can reach even higher temperatures. Remember, their strength slowly decreases above 1000°C. This temperature limit depends on the actual load and environment.

Are these ceramic slabs really strong?
Yes, these slabs are very strong. They resist compression extremely well. Their hardness is close to diamonds. This makes them excellent against wear and abrasion. They are brittle though. They can crack under sudden impact or severe bending stress. Handle them carefully.

Is the surface of these slabs smooth?
Yes, the surface is very smooth. It’s also non-porous. This smoothness minimizes friction. It also prevents materials from sticking. This is crucial for many industrial processes. The precise surface finish is achieved through careful grinding and polishing.

How do I clean 99% alumina ceramic slabs?
Cleaning is straightforward. Use common industrial cleaners or solvents. Avoid hydrofluoric acid. It damages the alumina. Mild abrasives work for tougher residues. The non-porous surface means most contaminants don’t soak in. Rinse thoroughly with water after cleaning.

Why pick 99% alumina over other ceramics?
99% alumina offers top performance. It provides the best combination of high temperature resistance, extreme hardness, and electrical insulation. It’s far more durable than lower purity alumina or other ceramics like steatite. It handles tougher jobs demanding maximum reliability and longevity.
