introduction of silica sand :
natural silica sand are classified into shore sand and sand mountain.quartz sand is mostly with impurity or mixtures, so generally it should treat differently when handling various mines .according to the content and particle size composition of fe2o3, al2o3, cr2o3, of tio2, grades are defined. 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 expansion
2.excellent conductivity and electrical property
3.pure(high sio2 content, low fe, na, k & ti)
4.high whiteness
5.high hardness, good wearable
