Silica and quartz sand can also make quartz sand after the crushing process, they are the main raw materials of glass industry.Feature of silica sand :1.very low coefficient of thermal expansion2.excellent conductivity and electrical property3.pure(high sio2 content, low fe, na, k & ti)4.high whiteness5.high hardness, good wearable
