Chromium-aluminum-silicon-zirconium-magnesium-iron spinel synthesis raw material as well as preparation method and application thereof
The invention relates to the technical field of refractory materials, in particular to a chromium-aluminum-silicon-zirconium-magnesium-iron spinel synthetic raw material as well as a preparation method and application thereof. The chromium-aluminum-silicon-zirconium-magnesium-iron spinel comprises the following components in percentage by mass: 25%-35% of Al2O3, 20%-35% of ZrO2, 20%-35% of Cr2O3, 5%-15% of SiO2, less than or equal to 5% of Fe2O3, less than or equal to 3% of MgO and the balance of impurities. Wherein the mass percent of the Fe2O3 and the mass percent of the MgO are both larger than 0. A refractory material product prepared from the chromium-aluminum-silicon-zirconium-magnesium-iron spinel synthetic raw material is stable in quality, few in stress crack defect and high in yield.
本发明涉及耐火材料技术领域，具体而言，涉及一种铬铝硅锆镁铁尖晶石合成原料及其制备方法和应用。铬铝硅锆镁铁尖晶石合成原料包括按照质量百分比计的如下组分：Al2O325%~35%，ZrO220%~35%，Cr2O320%~35%，SiO25%~15%，Fe2O3≤5%，MgO≤3%，余量为杂质；其中，所述Fe2O3和所述MgO的质量百分比均大于0。采用该铬铝硅锆镁铁尖晶石合成原料制得的耐火材料产品质量稳定，应力裂纹缺陷少，成品率高。
