Preparation method of magnesium aluminate spinel hollow spheres
The invention relates to a preparation method of magnesium aluminate spinel hollow spheres, and relates to the technical field of magnesium aluminate spinel products. According to the invention, high-quality high-purity light-burned magnesia, magnesite brick waste, industrial alumina, high-alumina bauxite and alumina waste are adopted as raw materials and are uniformly mixed, and the mixture is melted and blown at a high temperature of above 2450 DEG C. The product is a hollow sphere, and has the advantages of light weight and more excellent thermal insulation performance compared with the traditional magnesium aluminate spinel; energy is saved for downstream industries, the cost is reduced, the construction site difficulty is reduced, meanwhile, waste is recycled, mineral resources are saved, and the ecological environment is protected. Compared with light magnesium aluminate spinel or spinel balls prepared by adopting an ignition loss method, the magnesium aluminate spinel or spinel ball has the characteristics of high strength and high temperature resistance, and the product performance is more excellent.
本发明涉及一种镁铝尖晶石空心球的制备方法，涉及镁铝尖晶石制品技术领域。本发明原料采用优质高纯轻烧镁砂、镁砖废料，工业氧化铝、高铝矾土和氧化铝废料，均匀混合后经2450℃以上高温熔融吹制而成，由于本产品为空心球体与传统镁铝尖晶石对比有质轻、保温性能更优越的优势，为下游产业节约能源、降低成本、降低施工现场难度，同时废料循环再利用，节约矿产资源，保护生态环境。与采用烧失法制备的轻质镁铝尖晶石或尖晶石球相比具有强度高、耐温性能高的特点，制品性能更加优越。
