贵尝贬321、贵尝贬320
High purity natural quartz ingot ,made by flame fusion process, less bubble , high transparency and good geometry , optimum rate of utilization.
贵尝贬321贬、贵尝贬320贬
High purity natural quartz ingot with lower aluminum、low alkali metal elements.
FLH321HS
Almost bubble free, ultra-high purity, low alkali and low aluminum, almost no wrapping, strong high temperature resistance, it is an ideal window material.
贵尝贬321狈、贵尝贬320狈
Norwegian sand material , made by flame fusion process, less bubble, high transparency and good geometry , optimum rate of utilization.
The material has few bubble in it with excellent transparency and geometric dimension .They are widely used for semiconductor,Optical Fiber, Solar Energy Photovoltaics, Optical Coating/Filming.
Thanks to the few bubbles, high purity, almost no inclusion, high temperature resistant performance and other characteristics,FLH321HS has been widely used in semiconductor advanced manufacturing, optical, chemical processing, UV and high temperature window.
