从China供应商批发进口65%-97% Ccm Magnesium Oxide — FOB条款

Caustic calcined magnesite (CCM), also called light burnt magnesium powder or bitter earth powder, is an industrial magnesium oxide produced by calcining natural magnesite ore at 800 to 850 degrees Celsius. This offering from Liaoning Danding Industry Group Co., Ltd spans MgO content from 65% to 97%, with the finished product appearing in pink, yellow, or white depending on grade and calcination conditions. The material serves as the foundational feedstock for magnesia cement, thermal insulation boards, and a broad spectrum of magnesium chemical derivatives.

The lower end of the range (65-85% MgO) typically finds use in construction materials and agricultural applications where reactivity and cost balance matter. Mid-to-high grades (85-95% MgO) suit refractory brick manufacture, metallurgical flux, and environmental magnesium oxide applications. The top tier (96-97% MgO) approaches dead-burned magnesite purity and is reserved for electrical-grade magnesia, advanced ceramics, and high-performance refractories where low calcium and iron are essential. Standard industry impurities to monitor include calcium oxide, silica, and iron oxide, which rise in lower-grade material.

Buyers span refractory producers, magnesium chemical plants, fertiliser compounders, and environmental treatment facilities. Packaging is typically in 25 kg or 50 kg polyethylene-lined woven bags, or bulk in one-tonne big bags, though the exact format should be confirmed with the supplier. The Liaoning origin is significant: this province holds China's largest magnesite reserves and the densest concentration of calcination kilns, giving established logistics to Dalian and Yingkou ports for container or bulk shipment.

Liaoning Danding Industry Group Co., Ltd is located at No. 71-72 Fengcheng, Dandong, Liaoning Province, China. The supplier holds a harbor trust tier, which represents a baseline verification level on the platform. The response rate is recorded at 0.00% with an average response time of zero hours, indicating that buyer communication through the platform channel has not been established or the supplier has not engaged via this route. This does not preclude direct contact, but it does mean buyers should initiate outreach through multiple channels and document all communications.

The company's product focus centres on caustic calcined magnesite across a wide purity spectrum, leveraging the substantial magnesite reserves in Liaoning Province. The listing does not disclose production capacity, kiln type (rotary or shaft), export licence details, or ISO certification status. Buyers should request a current certificate of analysis for specific lots, confirm the calcination technology employed, and verify export documentation capability before placing trial orders. The Dandong location offers proximity to North Asian markets and alternative routing options, though most bulk exports move via Dalian port.
