タイトルまたは説明
High purity silica sand is processed from the quality silica
stone,for its high content of SiO2 and low impurity, it can be
used as material for producing optical glass, refractory,
metallurgy, ceramic, foundry abrasives and water treatment , also
can be used as the suitable for silicon metal and ferro silicon
industries or to synthesize high light alloy etc. Chemical
Composition and Partical Size Distribution: High purity grade:
SiO2:*9.*0%min**9.*8%min ; Fe2O3 :***5ppm Max.; size:****0 mesh
Refined grade: SiO2 :*9.*0%min**9.*0% min ; Fe2O3 : *****0ppm Max.;
size:****5 mesh General grade:SiO2 :*8.*0%min**9.*0% min ; Fe2O3 :
**0 ****0ppm Max.; size:****0 mesh We may produce it as our
client’s specification. High whiteness high purity quartz stone
High whiteness high purity quartz stone is mined from locally and
mountain areas inland. The Quartz stone with the characters of high
whitness, high purity, low impurity and low Electric Conductivity.
The quartz lumps are moved to our factory for crushing, water
washing and classifying to different grade for different usage, and
then supplied to customers or reprocessed in our factory. special
grade: SiO2: *9.*6%min; Fe2O3: 4ppm Max. 1st grade: SiO2:
*9.*0%min; Fe2O3: *0ppm Max. 2nd grade: SiO2: *9.*0%min; Fe2O3:
**0ppm Max. 3rd grade: SiO2: *9.*0%min; Fe2O3: **0ppm Max.
Crystalline micro-silica powder Crystalline micro-silica powder is
produced from white natural silica stone through the processing of
manual selection , ex-ior water dispose, fine gringing , filtrating
, drying and seiving ***** products , with high purity and white
colour, which has stable physical and chemical properties and
controllable particle size distribution, is widely used as material
for epoxy potting compound , epoxy mould compound of electronic and
electrical appliance industry. As well as engineering plastics ,
silicon rubber , precision ceramics , and casting , antispetic dope
and painting etc. We also can supply active silica powder of evry
specification , sinking time is not less than *5 minutes. Chemical
composition : SiO2: *9.5~*9.*0%min; Fe2O3: *0ppm Max.; Al2O3
:*0~*0ppm Max; size: **5 , **0, **0, **0, ***0 mesh etc. We may
product it acc. to our client’s request .
