The melted silica sand becomes amorphous silicon dioxide glassy ingot after being fused at high temperature(2000-2300 oC),and cooling. We further process the products into fused silica lump,sand and powder according to customer's requirements.Fused silica Special Feature:Fused Silica features extremely low coefficient of thermal expansion,consistent chemistry and carefully controlled particle size distribution.Fused silica Applications:Fused Silica are used in industry of thermal ceramic,refractory,investment casting,EMC,solar crucible,quartz marble,powder coating etc.Fused silica other sizes are available as follows : 0-1mm 1-3mm 3-5mm,,0.2-0.5mm,0.1-0.5mm-10mesh  10-20mesh, 30-50mesh, 50-100mesh,-100mesh,-150mesh,-270mesh,30-60mesh,60-120mesh,40-70mesh,70-140mesh,100-200mesh,120F, 200mesh, 325mesh, 400mesh ,600mesh , 800mesh, 1250mesh,etc...The partice size can be produced as customer's special requirment.Fused Silica high clear Pictures: Packaging & ShippingFused Silica Package and Delivery: paper bags,double layer jumbo bagsFused Silica Plastic Woven Bag of 25kg Net each,Then on Pallet:Fused silica Factory and Quality Control Pictures: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!ChemSize is manufacturer of fused silica which is produced by melting high purity natural silica sand(quartz sand)  at 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.Fused silica can be used to make crucibles that produce solar cells board in the photo-voltaic industry.Fused silica is used to make rollers, castables, mortars, gunning mixtures and forming tools in the glass industry.Fused silica is used to make technical ceramic in the thermal resistance industry.Fused silica is used to make ceramic slurry in investment casting industry.Fused silica is used to make Acidic acid refractory,Fused silica precast shapes,Fused silica big blocks and fused silica castablesChemSize is manufacturer of fused silica which is produced by melting high purity natural silica sand(quartz sand)  at 2200oC 12 hours.
