Quartz glass has a history of over 160 years in foreign countries, in 1839 the French first used the oxyhydrogen flame melting quartz quartz glass manufacturing, in 1902 the British electricity obtained using high temperature graphite rods (called single rod manufacturing quartz glass electric melting furnace), in twentieth Century 40s, invented the electric melting furnace in 50s even, with the development of semiconductor technology and the new power source (need a lot of quartz glass, quartz glass) developed rapidly. Because the production of quartz glass technology is difficult, until now can produce large quantities of quartz glass countries, only the United States, Germany, France, Japan, the United Kingdom, China and other countries.
China's quartz glass research began in 1957, before the founding of the People's Republic of China is blank. In 1956, the state formulated the 12 year plan for the development of science and technology, and requested the development of 57 key research tasks urgently needed by national defense to solve the new high-performance materials used in the two bombs and one satellite, and to make material preparations for the study of missiles and satellites. Quartz glass is the content specified in the twenty-sixth and fortieth task books, and the task is to be issued to the National Institute of building materials research. The development of China's quartz glass can be divided into 5 stages: from 1957 to 1961 for a stage, in order to study the manufacturing process method; 1962 - 1966 for the formation of industrial stage, many military tasks completed during the period, the yield and quality of products has greatly improved, has initially formed industry; from 1978 to 1988 as the period of reform innovative, high-tech quartz glass, such as large scale integrated circuit with high purity, high temperature resistant, high purity quartz glass tube coating crucible, arc crucible, optical quartz glass, quartz glass laser are in this period of research and mass production; from 1989 to 2000, the introduction of foreign advanced technology, technology innovation increase the varieties and yield period of great development, the most prominent is the development of Donghai County as a light source production of quartz glass base, with an annual output of 6000 tons (including the quartz glass Quality products more than 2000 tons), the quality of a great increase, the cost of several times decline, significant improvements in technology and equipment. More than 40 years, the development speed of quartz glass is faster, in the production of transparent quartz glass tube as an example: in 1975 production of 172 tons, 31 factories production by more than 60 tube resistance furnace, poor quality (now equivalent to 2 units, waste pipe) now even furnace can produce nearly 200 tons, to in 2000, the annual output of transparent quartz glass tube of 7000 tons (including 3500 tons of high-quality products for 25 years), an increase of nearly 40 times.
