溶凝胶 ,一种用来生产初级氧化物陶瓷玻璃的低温工艺 ,正逐步从实验室走向市场。预期用溶凝胶生产膜层、透镜和波导的光学工业在 2 0 0 3年将占溶凝胶体市场的 40 % ,据商务通信公司的估计。其时全球的溶凝胶销售量将达 3.4亿美元。虽然溶凝胶研究在过去十年有极大的增加 ,技术 Sol gel, a cryogenic process used to produce primary oxide ceramic glass, is gradually moving from the laboratory to the market. It is expected that the optical industry that produces films, lenses and waveguides with dissolved gels will account for 40% of the market for dissolved gels in 2003, according to estimates from Business Communications. At that time, global sales of dissolved gels will reach US$340 million. Although the study of dissolved gels has greatly increased over the past decade,
