5 FAQs of 1700C 85% Al2o3 Corundum Mullite Ceramic Crucible

What temperature can this crucible handle?
This crucible withstands temperatures up to 1700°C (3092°F) continuously. It resists thermal shock well. Avoid sudden temperature changes above 1500°C. This prevents cracking. The material stays stable under extreme heat.

What’s it made of?
The main material is 85% high-purity aluminum oxide (Al2O3), or corundum. The rest is mullite ceramic. This mix gives great strength. It offers excellent resistance to high temperatures. It also resists chemical corrosion.

What can I melt in it?
Use it for metals like gold, silver, copper. Use it for alloys. Use it for glass frits. Use it for some mineral samples. Avoid strong alkalis. Avoid hydrofluoric acid. These chemicals attack alumina. Confirm material compatibility first.

How do I handle it safely?
Handle it carefully. It is hard but brittle. Avoid impacts. Avoid squeezing. Wear gloves always. Thermal gloves protect your hands from heat. Mechanical gloves prevent cuts from sharp edges. Support the bottom fully during heating. Never place it directly on a cold surface hot.

How do I clean it?
Let it cool completely first. Remove residue mechanically. Use a scraper gently. Avoid metal tools scratching it. Wash it with water. Use mild acid like diluted nitric acid for stubborn deposits if compatible. Rinse thoroughly. Dry it completely before reuse. Do not thermal shock it cleaning.
