Magnesium Oxide (MgO) is a refractory white mineral oxide supplied by Shijiazhuang Kunmai Chemical Technology Co., Ltd. for industrial applications. With a molecular weight of 40.31 g/mol, this material exhibits exceptional thermal stability, making it a key raw material in steelmaking, cement production, and refractory linings. The product is available in fine powder form, suitable for use in ceramics, insulation materials, and chemical processing.
Industrial grades of MgO vary by purity and processing method, with typical assay values ranging from 85% to 99.5%. Light-burned magnesia, produced at lower temperatures, is reactive and used in agricultural and environmental applications. Dead-burned and fused magnesia, processed at higher temperatures, offer superior refractoriness for demanding applications such as furnace linings. Standard particle sizes for industrial MgO include 325 mesh and finer, depending on the application.
Buyers in the steel, construction, and ceramics industries source MgO for its high melting point (2852°C) and chemical inertness. Shijiazhuang Kunmai Chemical Technology Co., Ltd. supplies bulk quantities, with incoterms such as FOB or CIF commonly used for international shipments. The product is subject to standard industrial chemical export regulations, and buyers should confirm compliance with local safety and environmental standards.

Before ordering Magnesium Oxide from Shijiazhuang Kunmai Chemical Technology Co., Ltd., verify the supplier’s compliance with industry standards such as ISO 9001 for quality management. Request a Certificate of Analysis (CoA) for the specific batch to confirm purity, particle size, and other critical specifications. Buyers should also ensure the product meets the safety and environmental regulations of their target market, such as REACH or OSHA guidelines.
Confirm logistics details, including incoterms (FOB or CIF), lead times, and the port of loading in China. Magnesium Oxide is typically shipped in bulk bags or smaller sacks, so discuss packaging options and container loading to optimise shipping efficiency. Payment terms such as TT or LC should be agreed upon in advance, with clear milestones for deposit and balance payments to mitigate risk.
Conduct quality checks upon receipt, including visual inspection for colour consistency and particle size distribution, as well as analytical testing for purity and refractory properties. Request a Material Safety Data Sheet (MSDS) to ensure safe handling, storage, and disposal. For refractory applications, additional testing for thermal stability and chemical resistance may be required to confirm suitability for high-temperature environments.
