Product Description 1.Fused silica sandChem&Size minerals fused silica sand is made of fused silica ingot/lumps by hammer crusher and impact crusher.fused silica ingot/lumps is produced by melting high purity natural silica sand(quartz sand) at 1800-2200oC 12 hours. In the fusing process, the crystalline phase of silica sand transforms into amorphous phase. After cooling, Fused silica ingot is made out with high purity amorphous silicon oxide. Fused silica ingot is separated into 5-10cm lumps Grade A, Grade B and Grade C according to the black point size.2.Applications:High volume stability,high purity but low volumetric expansion makes fused silica sand a very useful and verstile material for refractory applications or other highly cyclical applications.Chem&size Minerals fused silica sand has an near zero thermal expansion coefficient,consistent chemistry and carefully controlled particle size distribution.Fused silica sand are designed for use in refractory,flow control/continuous casting,investment casting,precision casting,lost-wax process,technical thermal ceramic and other special applications.Fused silica powder has very high electrical resitivity and low thermal conductivity,so it used as filler in epoxy molding compounds for semi-conductors and fusion bounded epoxy powder coastings.3.Applications Details Product:to make crucibles that produce solar cells board in the photo-voltaic industry.Fused silica powder is used to make rollers, castables, mortars, gunning mixtures and forming tools in the glass industry,make technical ceramic in the thermal resistance industry,to make ceramic slurry in investment and to make Acidic acid refractory,Fused silica precast shapes,Fused silica big blocks and fused silica castables. 4.Typical Physical Properties Color and particle shapeWhite/grains/sandHardness7MohsTrue Specific Gravity2.21g/cm3Softening poingapprox.1650oCMelting pointapprox.1750oCBulk Density0.9-1.1mt/m3Dielectric Constant3.8(1MHz)Thermal Conductivity1.3w/m·kCoefficient of thermal expansion0.5*10-65.Fused silica chemical composition ItemProduct NameDescriptionChemical CompositionSize1Fused silicaGrade ASiO2>99.9%Al2O3<0.01%Fe2O3<30ppm(Al2O3<0.08% for powder) 0-1mm,1-3mm,3-5mm,4-10mesh,10-20mesh, 6-50mesh,-100mesh,-200mesh,-325mesh30-50mesh,50-100mesh2Fused silicaGrade ABSiO2>99.9%Al2O3<0.015%Fe2O3<40ppm(Al2O3<0.085% for powder) 0-1mm,1-3mm,3-5mm,4-10mesh,10-20mesh, 6-50mesh,-100mesh,-200mesh,-325mesh30-50mesh,50-100mesh3Fused silicaGrade BSiO2>99.85%Al2O3<0.02%Fe2O3<50ppm(Al2O3<0.09% for powder) 0-1mm,1-3mm,3-5mm,4-10mesh,10-20mesh, 6-50mesh,-100mesh,-200mesh,-325mesh30-50mesh,50-100mesh6.Particle size:Chem&Size minerals standard available size are:4-10mesh,10-20mesh,4-6 mesh , 6-16 mesh , 16-30 mesh , 30-50 mesh , 50-100 mesh ,-100 mesh , 120F , 270F, 325F , 400F , 8-5mm , 5-3mm ,3-1mm ,1-0mm ,1-0.5mm , 0-0.5mm , 0.5-0.2mm ,0.2-0.1mm , 0.5-0.1mm Special particle size distribution are also available as per customers' requirementsOther size are available if customers require.7.Package: in Paper bag or plastic woven bag of 25kg net each,then packed on pallet.in big bag of 1-1.2MT net each Fused silica making process Fused Silica is made of high purity crystal silica from China Donghai-Xinyi by electrically fusing (fusing temperature 1800-2000oC) to amorphous Silicon dioxide, then is specially engineered into lumps,cullet, ingots, sand,grain,granular and powder flour form designed for making PV fused silica crucible,thermal ceramic,refractory,EMC investment casting ceramic shell etc.Fused Silica sand Appearance and Specifications:1): It is forbidden to contain any unfused parts. 2): It is forbiden to have Foreign material, such as string, plastic line, carbon or wooden material, metal or other outside contaminants.3): All color dots is forbidden except conditional black dots4): It is not acceptable that black spot diameter is larger than 2mm.5): Total black dots quantity should be less than 10 when opening the big bag equal or less than 10 dots persquare metersFAQ:Q1. Can I have a sample order for fused silica products?A: Yes, we'd like to send samples free of charge by TNT/FEDEX/DHL. Mixed samples are acceptable.Q2. What about the lead time?A:It is 3-5 days for sending samples It is usually within 15 days to delivery orders for quantity within 100mt, Q3. Do you have any MOQ limit for fused silica sand order?A: No.But the less the average cost higher.Q4. How do you ship the goods and how long does it take to arrive?A: We usually ship by DHL, UPS, FedEx or TNT. It usually takes 3-5 working days to arrive. It depands on the distance by sea.7-40days.Q5. How to process an order for fused silica powder Products?A:1).let us know your requirements or application.2).We quote according to your requirements or our suggestions.3).customer confirms the samples and pay deposit for formal order.4).We arrange the production.Q6. Is it OK to print my logo on packages?A: Yes. Please inform us formally before our production and confirm the design firstly based on our sample.Q7: How to deal with the faulty?A: Firstly, Our products are produced in strict quality control system and the defective rate will be less than 0.2%.Secondly,If it happened,we shall arrange to send new products to you and pay for all your lost.Any question,kindly contact us please!
