272 Appendix D. Site Reports—Japan Site: National Industrial Research Institute of Nagoya (NIRIN) 1 Chome Hirate, Kitaku Nagoya 462, Japan Fax: (81) 52911 1661 Date Visited: 25 July 1997 WTEC: Hosts: J. Mendel (report author), D.M. Cox, C. Koch, H. Morishita, R.W. Siegel Dr. Shuzo Kanzaki, Chief Senior Researcher Dr. Mutsuo Sando, Research Manager Dr. Sakae Tanemura BACKGROUND The National Industrial Research Institute of Nagoya (NIRIN) has as its mission to carry out advanced materials research on ceramics, metals, composites, and related materials. Established in 1952, its main research field is material science and technology. There is close cooperation with domestic and global universities; there are also efforts to interface with other national research institutes. Within Japan’s National Industrial Research Institutes (NIRI) there are six major technical departments. In 1996, the annual budget for NIRI was $92 million (US). Total staff is 220 who participate in the Institute. For this visit, the WTEC panel focused on the area of synergy ceramics and materials. In the area of synergy ceramics, the emphasis is on structural control for improving a specific property of a given material. Here there is effort to simultaneously control structural elements at every stage (from atomic scale to the macro scale). This approach is referred to as “hyperorganized structure control.” In the area of synergy ceramics, there are a total of 30-35 people involved in the investigation of ceramics and metals. Size can be classified into four major categories for creating superior ceramic materials: (1) atomic and molecular scale, (2) nanoscale, (3) microscale, and (4) macroscale. In the hyperorganized approach to structure control, effort is made to harmonize and trade off functions, such as strength and toughness or electrical conductivity and stress sensitivity. In 1994, the synergy ceramics project was launched to foster collaboration among national research laboratories, universities, and industries. Part of the program is under the sponsorship of the New Energy and Industrial Development Organization
Appendix D. Site Reports—Japan 273 (NEDO) and is entrusted to the Fine Ceramics Research Association (FCRA). The Synergy Ceramics Project is divided into core research and satellite research projects. Core research is being carried out at NIRIN and at the Synergy Ceramics Laboratory located in the Japan Fine Ceramic Center (JFCC) by researchers from FCRA, NIRIN, and several national universities. Satellite research is being carried out by 12 industrial organizations participating in the FCRA and by the Osaka and Kyushu National Research Institutes. The projects that the WTEC panel were introduced to constitute only a portion of the core research. There are also many other topics being pursued as part of the Synergy Ceramics program. RESEARCH AND DEVELOPMENT HIGHLIGHTS Specific projects for synergy ceramics include the following: 1. alumina ceramics containing lanthanum oxide (La 2 O 3 ) 2. alumina ceramics doped with SiO 2 3. alumina ceramics doped with both La 2 O 3 and SiO 2 producing anisotropic grain growth of Al 2 O 3 and in situ plate growth of La 2 O 3 4. scaling of Si 3 N 4 with Y 2 O 3 and SiO 2 ; thermal conductivity values of SiN 4 are dependent on the processes of scaling and casting to improve strength, toughness, and Young’s modulus 5. nanoporous silica films with one-dimensional throughput channels of 10-20 nm; high temperature oxides of Fe 2 SiO 4 were prepared for evaluation as molecular sieves and particulate filters 6. preparation of submicron emulsions of Al 2 O 3 , surfactant and water; here, a silica coating is deposited on alumina powder; this coating makes the alumina surface negative over a broad pH range EQUIPMENT 1. ISO pressing (12 tons/cm 2 ) 2. Ceramic furnaces 3. Superplasticity measurement device 4. High resolution TEM
