Calcined Alumina (Al₂O₃, CAS 1344-28-1) from Zibo Jianhua Building Materials Co., Ltd. is a high-purity industrial oxide with a minimum Al₂O₃ content of 99%, designed for refractory, ceramic, and abrasive applications. The material is supplied in powder form with controlled particle sizes, typically ranging from 1 to 100 microns, and exhibits excellent thermal stability up to 1800°C. Its white, crystalline structure ensures low porosity and high mechanical strength in finished products.
The production process involves calcining aluminium hydroxide at temperatures above 1200°C to remove water and form alpha-alumina, the most stable crystalline phase. This results in a product with a true density of approximately 3.9 g/cm³ and a specific surface area of 1-10 m²/g, depending on the particle size. Calcined Alumina from Zibo Jianhua is standard for use in refractory castables, where it contributes to high-temperature resistance and chemical inertness.
This material is widely used in the steel, glass, and cement industries for lining furnaces and kilns, as well as in the production of advanced ceramics and abrasives. Buyers typically source it in jumbo bags or containers, with mesh sizes and Al₂O₃ content confirmed directly with the supplier. Its versatility extends to electronics, where it serves as a substrate or filler in components requiring thermal management and electrical insulation.

Before ordering from Zibo Jianhua Building Materials Co., Ltd., verify the exact Al₂O₃ content and particle size distribution, as these parameters directly impact performance in refractory and ceramic applications. Request a certificate of analysis (COA) to confirm purity levels and impurity concentrations, particularly for critical uses like electronics or high-temperature refractories. Ask for samples to test compatibility with your production processes.
Clarify logistics details such as lead time, which may vary based on production schedules in Shandong. Confirm Incoterms, with FOB or CIF being common for bulk shipments from China. Payment terms should be negotiated upfront, as these are not specified in the listing. Buyers should also discuss packaging preferences, as jumbo bags are cost-effective for large orders but may require specialized handling equipment.
For quality checks, inspect the particle size and colour consistency upon delivery, as deviations can affect performance in refractory castables or ceramics. Request documentation such as ISO 8007 or ASTM C71 compliance certificates, and consider third-party testing for critical applications. Ensure proper storage to prevent moisture absorption, which can cause clumping. Always follow workplace safety guidelines for handling fine powders to avoid inhalation risks.
