5 FAQs of 99.7% Al2O3 Alumina Ceramic Crucible Porcelain Square Crucible Welding Cutting Punching Services Lab Glass Melting Refractory

Here are 5 common questions about our 99.7% Alumina Ceramic Square Crucibles:

What temperature can these crucibles handle?
These crucibles withstand extreme heat. They work reliably up to 1750°C (3182°F). This makes them perfect for melting metals, glass, and other demanding lab or industrial processes needing high purity.

Do they resist thermal shock well?
Yes, they resist thermal shock very effectively. The high-purity alumina material handles rapid temperature changes well. This means you can heat them fast or cool them down quickly without cracking. It’s essential for many lab tests and metalworking jobs.

What chemicals won’t damage them?
These crucibles are highly resistant to most acids and alkalis. They won’t react with molten metals, fluxes, or harsh chemicals common in labs and foundries. This chemical inertness keeps your melts pure and the crucible durable.

How do I clean one after use?
Cleaning is straightforward. Let the crucible cool completely first. Remove leftover material mechanically if needed. Then, soak it in a suitable acid or solvent bath. Rinse it thoroughly with water afterward. Avoid sudden temperature changes during cleaning to prevent stress.

Can you customize the size or shape?
