Fused Silica
This Fused Silica is a kind of quartz crystal made of natural quartz sand high temperature smelting, transparent and white in color. At present, it is mainly used for making artificial crystal, glass, electronics, instruments, ceramics and refractory materials, etc.
Its main chemical components are shown as follows

Fluorspar
Fluorspar, widely used in modern metallurgical, chemical,weiding and cemen industries, is the principal material for extracting the element of fluorine. The export of our fluospar has had a history of well over thirty years and as with its superior quality it has enjoyed warm reception from our clients in all places. Hereunder is the general introduction of the various grades and specifications of our fluorspar available for export.
Fluorspar

(A)Acid Grade:
For extracting the element of fluorine,this grade is the unique material with the highest possible fluorine contents,Hydrofluoric acid and fluoride, produced with the fluorspar as materials, are widely used by such industries as chemicals and aluminium-smelting,etc.,and in the manufacture of freezing-mixture and disinfectant as will as in glass-carving.With the development of industry,fluoroplastics have been widely used in the industrial fields.
Specifications: 1.Filter Cake: Dry:
  CaF2 97% min. CaF2 97% min.
  SiO2 1% or 0.7% max. SiO2 1.5% max.
  CaCO3 1% max.80 Through 100 or 200 mesh
  H2O 10% max  
(B)Ceramic Grade:
In glass and ceramic industries,this grade is one of the major materials for manufacturing opal,coloured and opaque glass.
Specifications: CaF2 93%----95%
Fineness: Through 100 mesh
(C)Metallurgical Grade:
When used as a flux for smelting metals,this grade can reduce from the metals such impurities as silicon,sulpohur,phosphorus,etc.,to the suitable contents, and can aslo enhance the fluidity of the slag.
Specifications: CaF2 75%---90%
Sizes: In lumps.
