In the end the production of quartz glass, need annealing. What is the correct method of operation? Do you understand? Listen to the Beijing Cai quartz glass instrument factory Xiaobian to introduce you.
The production method of quartz glass is not the same as ordinary glass, the coefficient of thermal expansion is very small, for 5.5 * 10-7/ C, only the ordinary glass 1/12 - 1/20. Ministerial standards will be 1200 degrees after the rapid throw cold water to the sample burning, repeated more than three times is not allowed to burst. The synthetic quartz glass: 1025 C + 25 strain annealing point 1120 C + 25 1600 + 40 degrees of softening point
