This research has been divided into three groups. First, the solid state reaction group has fabricated the machinable Si_3N_4/BN composites with a high-strength, the Ba_yFe_xCo_<4-x>Sb_<12> with a good thermo-electrical property, the Ca-α-Sialon ceramics by carbothermal reduction, and has lead to the structure analysis of new martensite-transformation typed Gd_3GaO_6, the structure analysis of B-site substituted complex perovskite oxides with a good dielectric property, and the clarification of the interfacial reaction of ceria-coated alumina fibers. The second group was called the liquid phase reaction. This group has included the synthesis of rare-earth silicate single crystals with a high ionic conductivity of oxygen, the fabrication of TiO_2 on self-assembly films and its application of micro-patterning, the preparation and ferroelectrical property of Ba_2NaNb_5O_<15>, the preparation of SiO_2 films highly dispersed with nano-sized anatase crystals, and the synthesis of new carbon from various hydrocarbons, using several methods such as sol-gel, cooling of the melt, and hydrothermal. The final group has made the artificial lattices of ZrN_x-SiN_x and ZrN_x-GeN_x with super-conductivity, the multi-layered films of Fe/AlN and Fe/Nb with a giant ferro-magnetic property, the sintered ceramics of SiC-BN composite particles, and the clarification of the wet oxidation mechanism of various sialons.

这项研究分为三组。首先，固相反应组制备了可切削的高强度Si_3N_4/BN复合材料，具有良好热电性能的Ba_yFe_xCo_<4-x bbb_sb_ <12>，碳热还原法制备了Ca-α-Sialon陶瓷，并对新型马氏体相变型Gd_3GaO_6进行了结构分析，对介电性能良好的b位取代复合钙钛矿氧化物进行了结构分析。并澄清了氧化铈包覆氧化铝纤维的界面反应。第二组叫做液相反应。本小组的研究包括高氧离子电导率的稀土硅酸盐单晶的合成，自组装薄膜TiO_2的制备及其微图化的应用，Ba_2NaNb_5O_<15>的制备及其铁电性能，纳米锐钛矿晶体高度分散的SiO_2薄膜的制备，以及利用溶胶-凝胶、熔体冷却和水热等多种方法从各种碳氢化合物中合成新碳。最后一组制备了具有超导电性的ZrN_x-SiN_x和ZrN_x-GeN_x人工晶格，具有超强铁磁性能的Fe/AlN和Fe/Nb多层膜，SiC-BN复合颗粒烧结陶瓷，澄清了各种硅烷的湿氧化机理。
