近年来，一些国际著名化学公司大力发展超微细粉体材料工业，德国、美国和日本已成立了超微细粉体材料专业开发公司。日本是精细陶瓷研究开发较早的国家，90年代，日本和西欧生产新型陶瓷用超微细粉体材料的年总产值分别为71.5亿美元和15亿美元，年平均增长率分别为15.8%和18.9
In recent years, a number of internationally renowned chemical companies to develop ultra-fine powder materials industry, Germany, the United States and Japan have set up a ultra-fine powder materials professional development company. Japan is an early country for the research and development of fine ceramics. In the 1990s, the total output value of ultra-fine powder materials for producing new ceramics in Japan and Western Europe was 7.15 billion U.S. dollars and 1.5 billion U.S. dollars respectively, with an average annual growth rate of 15.8% and 18.9% respectively
