⚠️ Operating Environment & Precautions

✓ Suitable Environments:Oxidizing and reducing atmospheres; stable with air, water vapor, hydrogen, and carbon monoxide at high temperatures; suitable for fusion with weak alkaline fluxes such as anhydrous Na ₂CO₃.

✗ Strict Prohibitions:Do NOT use with strong alkaline substances (e.g., Na ₂O₂, NaOH) or acidic fusion environments (e.g., K ₂S₂O₇).

✗ Equipment Precaution:Do NOT place the crucible directly into a quartz tube, as high-temperature reactions may cause equipment damage.

💡Safe Handling:Allow crucible to cool below 200°C before removal to avoid thermal shock or burns.

❓ Frequently Asked Questions (FAQ)

Q: What is the maximum temperature your alumina crucibles can withstand?
A: Our 99% alumina crucibles support long-term use up to 1600°C, with a short-term maximum of 1800°C. We recommend allowing the crucible to cool below 200°C before removal to prevent thermal shock damage.

Q: Can you customize non-standard shapes and sizes?
A: Yes. We support square, arc, cylindrical, and various non-standard custom shapes. Standard ranges include square (side 60–330mm), arc (10–2300ml), and cylindrical (OD 30–376mm). Please send your drawings for a specific quotation.

Q: What is the difference between 99% alumina and 95% alumina crucibles?
A: 99% alumina offers higher purity, higher density (≥3.80 g/cm³), lower water absorption (≤0.01%), and better high-temperature and corrosion resistance compared to 95% alumina. It is preferred for high-purity and high-temperature applications.

Q: What substances should NOT be used with these crucibles?
A: Do not use with strong alkaline substances such as sodium peroxide (Na ₂O₂) or sodium hydroxide (NaOH), or acidic fusion agents like potassium pyrosulfate (K ₂S₂O₇). Also avoid placing the crucible directly in quartz tubes.

Q: What is the lead time for custom orders?
A: Standard sizes are available from stock with fast delivery. Custom orders typically take 15–30 working days depending on complexity and quantity.

Q: How do you ensure product quality?
A: Every crucible undergoes strict inspection: appearance check (no cracks, deformation, or impurities), dimensional inspection with calipers (tolerance ±2–3%), and physical/chemical property testing per relevant standards. Products are individually packed with shockproof materials.
