Quartz glass is a special industrial technical glass composed of a single component of silicon dioxide. It has a series of excellent properties unparalleled by ordinary glass. It is praised as the “king of glass” by experts in the field of new materials. , semiconductors and other national strategic emerging industries and important basic materials in the aerospace and other defense fields.
There is such a scientist who has been focusing on quartz glass for many years and has made an indelible contribution to the development of quartz glass in China. He is Gu Zhenan, an academician of the Chinese Academy of Engineering.
Expert resume
Gu Zhenan, born in Wuxi, Jiangsu Province in November 1936, is a professor-level senior engineer, doctoral supervisor, academician of the Chinese Academy of Engineering, and graduated from East China Institute of Chemical Technology (now East China University of Science and Technology) in 1958, majoring in silicate engineering. Member of the 863 New Materials Field Functional Materials Expert Group, Chief Engineer of National British Glass Quality Supervision; currently a professor and doctoral tutor of the China Academy of Building Materials Science, and the chief expert of the Quartz Glass Key Laboratory. In 1988, he was awarded the honorary title of the country’s young and middle-aged experts with outstanding contributions by the Ministry of Personnel; in 1991, he enjoyed the special government allowance of the State Council; in 1997, he was elected as an academician of the Chinese Academy of Engineering.
Research direction
Academician Gu Zhenan has been engaged in the research of special glass and optical fiber for a long time. He systematically studied the spectral and nonlinear optical properties of rare earth elements in quartz glass and optical fibers, and took the lead in carrying out chemical vapor deposition doping (DCVD), solution doping and oxyhydrogen flame melting in my country—two steps of electrofusion molding The research work of method technology has completed more than 20 national scientific research tasks, and successfully developed ultra-low expansion quartz glass, radiation-resistant quartz glass, cerium-doped quartz glass, ultraviolet filtering quartz glass, quartz glass for “Sanqi” project and rare earth. A batch of new materials with international advanced level, such as quartz optical fibers, provide key materials for key projects such as lasers, electronics, weapons, and aerospace, and achieve significant social and economic benefits.
Academician Gu Zhenan formulated the technological development plan, industrial policy and national standards of my country’s quartz glass industry, guided the construction of the product quality assurance system of key enterprises, established the only quartz glass research institute in my country and the National Quartz Glass Product Quality Supervision and Inspection Center to promote The development of China’s quartz glass industry. Currently, he participates in the strategic consulting project of the Chinese Academy of Engineering, and is responsible for the research on “Sustainable Development Strategy of Non-metallic Mineral Resources for Building Materials”, as well as research on topics such as “Resource-Saving and Environmentally Friendly Building Materials Industry” and “Development Strategy of my country’s Green Building Materials Industry”, focusing on cultivating graduate students .
