IntroductionSilica sand is one of the most common varieties of sandfound in the world. It is used for a wide range of applications,and can be purchased from various suppliers throughout the world.Silica sand is used in industrial processing, to make glass, asfill, and to create molds and castings. High purity quartzsand by the unique physical and chemical properties, making it inthe aviation, aerospace, electronic, mechanical, and the rapiddevelopment of today's IT industry occupies a pivotal position, inparticular its intrinsic molecular chain structure, the crystalshape and lattice variation, it has a high temperature, thermalexpansion coefficient is small, highly insulated, corrosionresistance, the piezoelectric effect, resonance effect and itsunique optical properties, in many high-tech products is playing anincreasingly important role Size:mesh10-20,20-40,40-80,80-120,120-180,200,etc Packing: 25kg/bag or as customer'srequirement Application Decoration,paintcoating,mineral vanish,epoxy flooring,relief Specification ITEMS/SPECSGLASS SANDNATURAL SILICASANDHIGHPURITYSILICASANDCRYSTALLINSANDSIO299%99.5%99.9%99.99%AL2O3¡¡0.12%300PPM30PPMFE2O30.06%0.03%50PPM1PPMCAO¡¡0.01%50PPM1PPMMGO¡¡0.005%10PPM1PPMK2O¡¡0.01%50PPM1PPMNA2O¡¡0.01%50PPM1PPMIgnitionLoss¡¡0.1%0.08%0.01%MOISTURECONTENT4%¡¡0.08%0.008%WHITENESS¡¡88-9292-95>=95DIAMETER0.2-0.8MM95%MIN4mesh-200mesh4mesh-200mesh4mesh-200mesh PhysicalRequirementsParticleSize 0.4-0.55Proportion g/cm3 2.6Bulk Density g/cm3 1.70Relative Density 20° /g/cm3 1.0PH 1% Solution 7.0Breakage /% 0.48Wear rate /% 0.3Clay content /% 0.5Porosity /% 43~47Hardness(Mohs) 7.7 E0573,Silica sand/Quartz sand,abrasive material.
