5 FAQs of High Temperature Alumina Ceramic Crucible Boat for Melting or Analyzing Metal

What temperature can these crucible boats handle?
Alumina ceramic crucible boats work reliably up to 1750°C (3182°F). This suits most metal melting and analysis jobs. They keep their shape and strength at these high heats. Check the exact grade for its specific limit.

Can they handle fast temperature changes?
Yes, they resist thermal shock well. You can heat them up fast or cool them down fast. This matters for repeated use in furnaces or rapid cooling tests. They are less likely to crack than some other materials.

Do they react with molten metals?
Alumina ceramic is highly inert. It resists attack from many molten metals and alloys. This includes metals like gold, silver, copper, and platinum. It also works well with various fluxes and slags. Always confirm compatibility with your specific metal first.

How long do these crucibles last?
Lifespan depends heavily on use. Factors include peak temperature, heating/cooling speed, and the metal type. Gentle handling extends their life. They withstand repeated thermal cycling better than cheaper materials. Expect many uses under normal conditions.

How should I clean them after use?
Remove cooled metal carefully. Avoid mechanical shock. Use dilute acid baths for tough residues. Hydrochloric acid (HCl) often works well. Rinse thoroughly with water after cleaning. Ensure they are completely dry before reheating to prevent cracking.
