For quartz instruments, purity has a huge impact on performance. Purity is an important indicator of quartz glass and has a great impact on physical and chemical functions and use functions, such as devitrification, high temperature strength, softening point, light transmission, thermal stability, chemical stability, radiation resistance, fluorescence characteristics, etc. The following is a brief introduction to the importance of quartz instrument purity, hoping to help you.
Quartz glass used in the semiconductor industry has more stringent requirements for purity. A small amount of impurities will have a serious impact on the motor energy, life and integration of semiconductor materials. Because the purity of semiconductor materials is required to be controlled below the ppb level, quartz glass should be controlled at the PPm level to meet the needs of the semiconductor industry.
The segregation coefficient of B is close to 1, and Z is difficult to remove. It is one of the harmful impurities of Z. Cu, Fe, Ti, etc. affect the minority carrier life of semiconductors. K, Na, Li are harmful impurities that produce microdefects in single crystal materials. The company has served the semiconductor industry for more than 40 years and has always been committed to the research and development of removing the above harmful impurities.
