摘要
铝灰是一次和二次铝工业的废弃物,研究利用铝灰提取氧化铝、棕刚玉、合成Sialon、镁铝尖晶石、TiN-AI_2O_3复合材料、莫来石、聚合氯化铝及硫酸铝等耐火材料的重要原材料和结合剂,并使其尽快投入生产,这样既节能环保,又能降低成本,提高经济效益。
Aluminum ash is the waste of primary and secondary aluminum industry. Aluminum oxide, brown corundum, synthetic sialon, magnesium aluminum spinel, TiN-Al2O3 composite material, mullite, polymerized aluminum chloride and aluminum sulfate and other refractory raw materials and binders with aluminum ash were studied.Aluminum ash reusing should be promptly pushed, which is beneficial for energy saving and environmental protection,costs reducing and economic benefits improving.
