从China供应商批量进口Aluminum Hydroxide For Making Aluminum Oxide

Aluminum hydroxide, Al(OH)3, is a white amorphous powder used primarily as a precursor in the Bayer process for producing aluminum oxide (alumina). The material supplied by Qingdao Huierde International Trade Co., Ltd originates from China and is positioned for industrial-scale buyers seeking feedstock for calcination operations. The source data indicates purity above 99% with controlled silica (SiO2) and iron oxide (Fe2O3) content, though buyers should request a current certificate of analysis to confirm exact impurity thresholds for their intended thermal conversion process.

In typical industrial practice, aluminum hydroxide decomposes to alumina at temperatures between 200°C and 1200°C depending on the desired alpha or gamma phase. The particle size distribution, median diameter, and specific surface area (BET) are critical parameters that determine calcination efficiency and final alumina reactivity. Standard grades for smelter-grade alumina production require low alkali content and specific loss-on-ignition profiles. The material is usually supplied as a free-flowing powder with bulk densities ranging from 0.4 to 1.1 g/cm3 depending on precipitation conditions and post-treatment.

Primary buyers include alumina refineries, ceramics manufacturers, and producers of specialty aluminum chemicals. For flame retardant applications, the same chemical functions as a smoke-suppressing filler in polymers, though this requires different surface treatment and particle morphology. Importers should discuss packaging format (typically 25 kg bags, 1000 kg bulk bags, or bulk pneumatic discharge), moisture specifications, and required documentation including SDS and REACH compliance with Qingdao Huierde directly. The supplier's Harbor trust tier and 0.00% response rate suggest limited engagement history, so direct communication to confirm current availability and technical support capability is advisable.

Qingdao Huierde International Trade Co., Ltd is registered at Fuzhou South Road, Qingdao, 266032, China, placing it within Shandong Province's established chemical trading corridor with access to Qingdao Port. The supplier holds an imported tier classification, indicating it sources material rather than manufacturing directly, and carries a Harbor trust tier. The response rate is recorded at 0.00% with zero average response hours, which indicates no tracked inquiry engagement through the platform and should prompt buyers to establish direct contact to assess communication reliability.

The company profile does not disclose manufacturing assets, warehouse capacity, in-house laboratory capability, or specific quality management certifications. No ISO, SGS, or other third-party audit status is confirmed in the available data. Buyers should verify the supplier's actual trading experience with aluminum hydroxide specifically, its relationships with upstream precipitator plants, and its ability to provide consistent lot-to-lot documentation. The listing focuses on bulk supply flexibility and international standards compliance, though the exact standards referenced are not specified.
