High-pressure research in Japan

Authors


Abstract

The field of high-pressure research in Japan has a long history, dating from early efforts at the beginning of this century to compress gases to an era of broad but intense activity during the past 20 years to study solid state properties of materials. In a recent report released by the U.S. Office of Naval Research located in Tokyo (E. F. Skelton, High-Pressure Science and Technology in Japan, Rep. ONRTM1,1979), the research being done in 43 Japanese High-Pressure Laboratories is described in detail. A large proportion of the research is related to solid state physics and chemistry, but an equally large proportion is related to geophysical studies. There are industrial programs in Japan to develop ‘superhard’ materials, such as diamond and cubic boron nitride, although the emphasis is on basic research rather than production.
