Physical and chemical indexes of silica sand
Physicochemical properties of silica sand
The density of silica sand is 2.65, that is, the density of water is about 2.65 times.
Silica sand is a hard, wear resistant, chemically stable silicate mineral,The silica sand main mineral composition is sio2.Silica sand color is milky white, or colorless translucent,Colorless or translucent, hardness 7,Brittle cleavage,Shell like fracture, oil sheen, density of 2.65,Bulk density (1-20 = 1.6),20-200 target is 1.5,Its chemical, thermal and mechanical properties have obvious anisotropy, insoluble in acid, slightly soluble in KOH solution, melting point 1750℃.
Main specifications of silica sand :
Silica sand commonly used specifications:0.5-1mm,1-2mm,2-4mm,4-8mm,8-16mm,16-32mm,10-20 mesh,
20-40 mesh,40-80 mesh,80-120 mesh,100-200 mesh,200 mesh,325mesh
Main classification of Silica sand
Quartz has high fire resistance,Silica sand is usually divided into:Ordinary silica sand ,Refined silica sand ,High purity silica sand ,Fused silica sand and silica powder
Refined silica sand , also known as pickling silica sand ,SiO2≥99-99.5% Fe2O3≤0.005%,High quality natural silica sand
High purity silica sand :SiO2≥99.5-99.9% Fe2O3≤0.001%,Uses the high quality natural quartz stone, mortar .
Fused silica sand:Chemical composition SiO2 99.9-99.95% Fe2O3 5PPM-25PPM max Li2O 1-2PPM max Al2O3 20-30PPM max K2O 20-25PPM max Na2O 10-20PPM max (PPM is a unit of a million).Physical properties:The appearance is colorless transparent block, particle or white powder.Relative specific gravity:2.21 ; Mohs hardness:7.0 ;The value of ph:6.0 ;
Silica powder:Appearance of gray or white powder, refractoriness >1600℃.Bulk density: 200~250 kg / cubic meter
The chemical composition of silica powder is shown in the following table:
item average value PH
SiO2 75~96%
Al2O3 1.0±0.2%
Fe2O3 0.9±0.3%
MgO 0.7±0.1%
CaO 0.3±0.1%
NaO 1.3±0.2%
