Silica sand is created by crushing quartzite or sand stone, and washing and grading it to produce required grain distribution. Silica flour is made by grinding, crushing and washing the superior grade quartz, quartzite rocks or from white silica sand.CHEMICAL COMPOSITION:
Sio2 the general impurities are iron/aluminium oxides and lime.SPECIFICATION :
Grade 1 Anticipated for the manufacturing of decolorized glassware, such as lamp ware and container ware.
Grade 2 Used for the making of glassware where slight tint is admissible.
Grade 3 envisioned for the manufacture of glasses like colored glass, sheet glass.USES :
Silica sand is used for making of glass and water purification, disodium ultramarine, synthetic foundry molding catalysts etc. It is also used for refractory, acid heat resistant ceramics, enamel pottery glaze etc. Silica sand of 150 mesh is used in grinding and surfacing glass, Sawing stone. Rounded Grains of silica sand are used for filler in paints, sand blasting, gypsum plasters, soap molded hard rubber goods, and oxychloride acoustic plasters.GEOLOGICAL SETTING:
: It appears as loose or weakly amalgamated deposits of sedimentary source or as dunes blow inland from the coast or as gathered deposits in estuaries. PHYSICAL PROPERTIES
