New processes on the structure-controls and property-evaluation of ceramics

陶瓷材料可分为五大类，即粉末、单晶、烧结体、复合材料和玻璃。然后将所有研究者分成五组，对陶瓷结构控制的新工艺进行如下研究。(1)粉末，(2)单晶，(3)烧结体，(4)非晶材料，(5)复合材料的结构控制和性能评价。每个调查员都属于其中一个小组，研究各自的问题。会议分别于1986年1月20日和21日以及1987年2月2日和3日在仙台市郊区举行，讨论了“陶瓷结构控制和性能评价的新工艺”等问题。并对上述问题的发展前景进行了展望。提纲说明如下。利用热力学、平衡理论和化学动力学对气、液、固相法制备粉末的工艺过程进行了重新安排，这些结果反映在粉末的结构控制和性能评价上。利用化学键理论、扩散理论和平衡理论对单晶微观结构与性能之间的关系进行了研究，并对结果进行了重新整理。研究了烧结体的宏观结构与性能之间的关系，并用断裂力学和统计理论对这些结果进行了重新整理。对各种非晶材料的组成、相分离结晶与性能的关系进行了研究，并对研究结果进行了科学的整理。研究了复合材料功能或特性的改善与微观组织的关系，并对结果进行了科学整理。部分研究结果在日本化学学会、日本金属学会、日本陶瓷学会等会议上发表。少

Ceramic materials are able to divide into five groups, i.e. powders, single crystals, sintered bodies, composites and glasses. Then all investigators were also divided into five groups in order to study the new process on the structure-controls of ceramics as follows. Structure-controls and property-evaluation of (1) powders, (2) single crystals, (3) sintered bodies, (4) amorphous materials, (5) composites. Each investigator belonged to one of these groups and studied respective problems. The meetings were held at January 20th and 21st 1986 and February 2nd and 3rd 1987 both in the suburbs of Sendai city, and many subjects on "new processes on the structure-controls and property-evaluation of ceramics" were discussed. There the future prospects of the above mentioned problems were ascertained. The outline is indicated as follows.1. Powder preparation process by gas, liquid or solid phase method were rearranged by using the thermodynamics, the equilibrium theory and the chemical kinetic … More s. These results were reflected to the structure-controls and property-evaluation of powders.2. Relationship between the micro-structure and properties on single crystals were studied and these results were rearranged by using the chemical bonding theory, the diffusion theory and the equilibrium theory.3. Relationship between the macro-structure and properties on sintered bodies were studied and these results were rearranged by using the fracture mechanics and the statistical theory.4. Relationships between the composition, phase separation crystallization and the properties on various amorphous materials were studied, and these results were scientifically rearranged.5. Relationship between the improvement of functions or characteristics and the micro-structure of composites were studied, and the results were scientifically rearranged.The part of these results were reported at the meetings of the Chemical society of Japan, the Japan Institute of Metals, the Ceramic society of Japan and so on.
