该商品不支持网上交易产品中引入Fe2O3的成分，使之在高温下扩散到镁铝尖晶石砂中的方镁石晶格内，脱溶出镁铁尖晶石MF，MF在方镁石中的溶解度随温度的波动而变化，有助于方镁石晶格的活化，促进方镁石晶体的长大和制品烧结，使制品高温性能得到改善。制品中的Fe2O3和Al2O3，与水泥熟料中的物质发生反应，形成低熔点矿物相，该矿物相具有一定的粘度，可粘附在衬砖的热面形成稳定的窑皮。
Based on synthetic high-Fe magnesia and spinel clinker, this brick is a perfect substitute of direct-bonded magnesia chrome brick but more environmental friendly. The introduction of Fe2O3 make itself spreading into the crystal lattice of periclase, and exsolute Iron Magnesia spinel (MF); the solubility of MF changes with temperature, and adds flexibility to the crystal lattice, thus improves the thermal capability of material. The Fe/Al in the refactory reacts with cement clinker, and forms the low-melting-point mineral facies. With certain level of viscosity, it helps a stable coating on the lining.
