5 FAQs of High Purity Conical Laboratory Refractory Porcelain Alumina Ceramic crucible For Thermal Analysis

1. **What temperature range can the high purity alumina ceramic crucible withstand?**
The crucible is designed for extreme thermal conditions, capable of withstanding continuous temperatures up to 1800°C (3272°F) and short-term exposure to 1900°C (3452°F). Its refractory properties ensure minimal thermal expansion, making it ideal for thermal analysis processes like TGA, DSC, or ash determination where rapid heating or cooling cycles are common.

2. **Is this crucible chemically resistant to aggressive substances?**
Yes, the high-purity alumina (≥99.6% Al₂O₃) construction offers excellent resistance to acids, alkalis, and molten salts at elevated temperatures. However, prolonged exposure to hydrofluoric acid (HF) or strong caustic solutions above 1000°C may cause gradual degradation. Always verify chemical compatibility with your specific sample materials before use.

3. **Why choose alumina over quartz or platinum crucibles?**
Alumina outperforms quartz in thermal shock resistance and maximum temperature tolerance, while being more cost-effective than platinum. It’s non-reactive with most inorganic samples, avoids contamination in oxidation/reduction environments, and provides superior durability for repeated high-temperature experiments.

4. **How should I handle and store these crucibles to prevent damage?**
Avoid mechanical shock or abrupt temperature changes, as alumina is brittle. Use tongs for handling at high temps. Store in a dry, contaminant-free environment, preferably in padded containers. Pre-heat crucibles gradually (2-5°C/min) to minimize thermal stress. Never place cold crucibles directly into high-temperature furnaces.

5. **Can these crucibles be reused, and how do I clean them?**
Yes, they are reusable if undamaged. Remove residues by soaking in diluted hydrochloric acid (HCl) or nitric acid (HNO₃), followed by ultrasonic cleaning. Avoid abrasive scrubbing. Rinse with deionized water and dry at 150°C before reuse. Inspect for cracks or warping after each cycle—discard if defects appear to ensure measurement accuracy and safety.
