5 FAQs of Polished Al2O3 Ceramic Plate Alumina Square Block

Here are 5 FAQs for Polished Al2O3 Ceramic Plate Alumina Square Block:

What sizes do these polished alumina plates come in?
We offer many standard sizes. Common thicknesses are 3mm, 5mm, 10mm. Common square sizes are 50x50mm, 100x100mm, 150x150mm. Custom sizes are possible. Contact us for specific needs.

How much heat can this alumina block handle?
This ceramic handles very high temperatures. Its maximum continuous use temperature is 1600°C (2912°F). It works well in furnaces and high-heat processes. Avoid extreme rapid temperature changes. Sudden shifts might cause cracks.

Why is the surface polished?
Polishing creates a super smooth, flat finish. This smoothness stops samples or materials sticking. It allows easy cleaning. The flatness ensures precise work surfaces. Polishing reduces friction and wear.

Can I machine or cut this plate myself?
No. Do not try cutting or drilling this yourself after purchase. Alumina ceramic is very hard. It is also brittle. Attempting machining will likely break it. Order the exact size and shape you need. We make it ready for you.

How do I clean this alumina ceramic plate?
Cleaning is simple. Use warm water and mild soap. A soft cloth or sponge works well. Rinse thoroughly. Dry it completely. Avoid strong acids or alkalis. These chemicals can damage the polished surface over time. For tough stains, very fine abrasive powder might work gently.
