Refractory-Grade Calcined Bauxite from Germany
Refractory-grade calcined bauxite is thermally treated to achieve over 85% alumina content, used in high-temperature furnace linings and kiln furniture. It is categorized under HTS 2606.00.0060 for other calcined bauxite concentrates. The calcination process densifies the ore for superior heat resistance.

Import Tips
• Include thermal expansion and refractoriness test data (e.g
• Orton cone) in import docs
• Distinguish from synthetic alumina by providing mineralogical analysis showing bauxite origin
• Avoid bulk packaging pitfalls; use ventilated containers to prevent moisture reabsorption
