作者一直在探索在有机溶剂中在高于其沸点的温度（200-300 ℃）下合成无机材料（溶剂热反应），并开发了合成金属氧化物超细颗粒的各种反应方法。本文首先综述了铝化合物（氢氧化铝（Al（OH）3;三水铝石）、铝醇盐和铝盐）在各种有机溶剂（醇类、二元醇类、氨基醇类和惰性有机溶剂）中的反应，讨论了反应机理以及原料和溶剂对产物的影响。然后，使用二醇，特别是1，4-丁二醇（糖热反应）的特异性，澄清，和结晶混合氧化物，如钇铝石榴石的糖热合成进行了描述。最后，溶剂热制备的产品作为催化剂材料的用途进行了说明。
The author has been exploring the synthesis of inorganic materials in organic solvents at temperatures (200–300 °C) higher than their boiling points (solvothermal reaction), and has developed various reaction methods for the synthesis of ultrafine particles of metal oxides. In this paper, the reactions of aluminium compounds (aluminium hydroxide (Al(OH)3; gibbsite), aluminium alkoxides, and aluminium salts) in various organic solvents (alcohols, glycols, aminoalcohols, and inert organic solvents) are first reviewed, and reaction mechanisms and effects of the starting materials and solvents on the products are discussed. Then, the specificity of the use of glycols, especially 1,4-butanediol (glycothermal reaction), is clarified, and glycothermal synthesis of crystalline mixed oxides such as yttrium aluminium garnet is described. Finally, the use of the solvothermally prepared products as the catalyst materials is described.
