5 FAQs of 99 Al2o3 Alumina Ceramic Boat Crucible / Rectangular Crucible With Cover

What’s the highest temperature this crucible can handle?
This alumina ceramic crucible handles extreme heat well. It withstands temperatures up to 1700°C (3092°F) continuously. That’s suitable for most lab furnaces and kilns. Avoid exceeding this limit. Doing so risks damaging the crucible.

Will chemicals damage the ceramic?
The 99% Al2O3 ceramic resists most chemicals superbly. Acids and alkalis generally don’t harm it. But avoid very strong acids like hydrofluoric acid. Avoid very strong bases too. These can etch the surface over time.

Can it handle sudden temperature changes?
It has moderate thermal shock resistance. Don’t heat it or cool it too fast. Avoid big temperature jumps. Sudden changes might cause cracks. Heat and cool it gradually for best results. This greatly extends its life.

How do I clean it after use?
Cleaning is straightforward. Let it cool completely first. Use a soft brush with water or mild detergent. For stubborn residue, use fine alumina sand or powder. Avoid harsh abrasives or metal tools. These can scratch the ceramic surface.

What size fits my furnace?
Measure your furnace’s hot zone carefully. Our crucibles come in many standard sizes. Check the exact dimensions listed for each product. Width, length, and height are critical. Ensure the crucible fits inside your furnace with space around it.
