Import Calcined Alumina Powder — Buy in Bulk from Supplier in China

Zhongtian Special Alumina Co., Ltd supplies industrial‑grade calcined alumina powder that is recognised for its high thermal stability and chemical resistance. The product is described as high‑purity aluminium oxide (Al2O3) and is produced to meet demanding performance criteria in ceramics, electronics and refractory sectors. Although the exact mesh distribution is not listed, the supplier notes a fine particle size distribution that aligns with typical industry requirements. Packaging is offered in bulk quantities suitable for large‑scale manufacturing, with standard freight options such as FOB and CIF.

Typical commercial alumina powders exhibit a purity of 99.8 % Al2O3 or higher, a bulk density around 1.5 g/cm³ and a moisture content below 0.3 %, all of which are consistent with the attributes of Zhongtian's offering. Particle size is often characterised by a d50 value near 5 µm, and a specific surface area of approximately 8 m²/g, which supports uniform sintering in advanced ceramic processes. The powder is usually supplied in white colour, a standard that helps differentiate it from brown variants used in other applications. These typical specifications make the material compatible with high‑precision ceramic components and electronic substrates.

Manufacturers of advanced ceramics, refractory linings and high‑performance abrasives are the main buyers of this calcined alumina powder. Zhongtian emphasizes flexible order volumes, allowing purchasers to scale quantities according to production needs. While the listing does not disclose exact lead times, prospective buyers should confirm delivery schedules, incoterms and payment conditions directly with the supplier. The combination of harbour‑tier verification and reference to ISO/SGS certifications provides a baseline of trust for international procurement.

Zhongtian Special Alumina Co., Ltd. is based at No.31 West Of Anyang Road, Shangjie District, Zhengzhou, Henan Province, China. The company carries a harbour‑tier verification, indicating it has satisfied basic compliance checks on the platform.

The supplier profile does not provide response‑time statistics, and the listed response rate is 0.00, so buyers should proactively verify communication availability. Zhongtian markets its calcined alumina powder for global export and highlights adherence to international standards, though no specific certification documents are attached to the listing. Additional corporate details such as establishment year or workforce size are not disclosed and should be requested if relevant to the procurement decision.
