White Corundum
White Corundum supplied by Gongyi City Hong The Refractory Material Co., Ltd. is a synthetic abrasive composed of white fused alumina (Al2O3) with a purity exceeding 99 %. The material exhibits a Mohs hardness of nine and a Knoop hardness between 2000 and 2200 kg mm‑2, while its bulk density ranges from 1.53 to 1.99 g cm‑3. Chemical analysis shows Al2O3 content above 95 %, Fe2O3 not exceeding 0.4 %, Na2O ≤0.22 % and SiO2 ≤0.04 %.
The product is offered as a fine‑grade powder suitable for wet sand‑blasting, polishing and ultra‑precision grinding. In the abrasive industry, white fused alumina is the preferred choice for applications that must avoid iron contamination, such as aerospace component finishing and semiconductor wafer processing. Typical industry grades are supplied in grit sizes from F30 to F120, with a typical moisture content below 0.1 % to maintain flowability.
Import buyers use this corundum for refractory linings, precision casting sand, and surface preparation of hardened steels. It is especially valued by manufacturers of grinding wheels, polishing compounds and high‑temperature ceramic additives. Trade terms, packaging options and incoterms should be confirmed directly with the supplier, as the listing does not specify minimum order quantities or lead times.

Sourcing White Corundum from Gongyi City Hong The Refractory Material Co., Ltd. - China Import Guide
Before confirming an order, verify the supplier’s production capability and request a recent batch test report covering chemical composition, hardness and bulk density. Ask for a sample if possible, and confirm that the material meets any industry standards required for your downstream process.
Clarify the preferred incoterm, typical lead time and payment terms directly with the supplier, as these details are not disclosed in the listing.
