Basic features of Soft, Solution Processing are discussed. Pioneering research carried out in our laboratory on in situ fabrication of morphology controlled advanced ceramic materials by Soft. Solution Processing (synthesis of double-oxide ABO3.ABO4 films by hydrothermal, electrochemical, hydrothermal-electrochemical maethods, coating of CaTiO3 on TiAl, preparation of carbon films on SiC,hydroxyapatite whiskers and fine powders under hydrothermal conditions) is reviewed. Soft, Solution Processing allows to fabricate in aqueous solutions shaped/sized/oriented ceramics in only one step, without excess energies for firing/sintering or melting and without expensive equipment, providing an environmentally firiendly route for preparation of advanced ceramic materials.

讨论了软溶液处理的基本特征。在我们的实验室进行了开创性的研究，在原位制备形貌控制的先进陶瓷材料的软。综述了溶液法（水热法、电化学法、水热-电化学法制备ABO 3、ABO 4复合氧化物薄膜，水热法在TiAl表面包覆CaTiO 3，水热法在SiC表面制备碳膜，水热法制备羟基磷灰石晶须和超细粉体）的研究进展。软，溶液加工允许在水溶液中仅在一个步骤中制造成形/尺寸/取向的陶瓷，而无需用于烧制/烧结或熔化的多余能量，也无需昂贵的设备，为制备先进的陶瓷材料提供了一种环境友好的途径。
