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

99% Al2O3 Alumina Ceramic Boat Crucible / Rectangular Crucible With Cover – FAQs

1. What temperature can this crucible handle?
This crucible withstands very high heat. Its maximum continuous use temperature is 1650°C (3002°F). Avoid exceeding this limit. Doing so risks damaging the crucible. It might crack or degrade faster.

2. Can it handle sudden temperature changes?
Yes, it resists thermal shock well. Thermal shock means quick heating or cooling. This alumina ceramic handles those rapid shifts better than many other materials. Still, avoid extreme, unnecessary temperature swings. Gradual heating and cooling are always safer.

3. What chemicals work with this crucible?
This crucible fights chemical attack effectively. It works with strong acids and bases. It handles molten salts and many aggressive chemicals. It’s highly resistant to oxidation. Check its compatibility for your specific chemicals first. Some very strong fluxes might still cause issues.

4. How do I clean it after use?
Cleaning is usually straightforward. Let the crucible cool down completely first. Remove loose residue mechanically. Gentle scrubbing often works. For tougher residues, soak the crucible in a suitable acid or solvent. Avoid harsh mechanical abrasion. That could scratch the surface. Never thermal shock it to clean it.

5. How long will this crucible last?
Lifespan depends heavily on use conditions. Factors matter: maximum temperature reached, duration at high heat, chemical exposure, thermal cycling frequency, and handling care. Used correctly within its limits, it offers good longevity. Expect gradual wear over time. Inspect it regularly for cracks or thinning. Replace it when signs of significant wear appear.
