1.Technological Characteristics
Determine the value of industrial application,silica is
characteristic of the process silica hard , Mohs hardness of 6 or
so ,have excellent fire resistance and acid-resistance ,
melting point ***0°C,the melt after cooling into a quartz
glass ,crystal to crystal ,with a transparent UV
light had the ability and piezoelectricity.
2.main purpose
1)tallurgical industry : mainly for the manufacture of refractories
silica,smelting silicon alloys and for the flux ,Quality of pure
crystalline silicon can be prepared,crystalline silicon is the main
raw material for production of silicon , but also the system
alumina and silicone.
2)Glass industry manufacture of glass , silica is the main rew
material ,silica can be used for ordinary and poptical glass ,may
melt into a mass of pure high-quality technical glass Bricks can be
used for glass furnace kiln lining.
3)Construction industry can be used as an important cornerstone of
the buliding ,Can be filled with gravel for road stone and railway
ballast sand can be mixed with asphalt paving ,portland cement can
be made of quartz calibration material.
