99.7%/td>99%) in local Donghai/Xinyi as our raw material. 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.brFused silica Special Feature:brFused Silica features extremely low coefficient of thermal expansion,consistent chemistry and carefully controlled particle size distribution.brFused silica Applications:brFused Silica are used in industry of thermal ceramic,refractory,investment casting,EMC,solar crucible,quartz marble,powder coating etc.brFused silica other sizes are available as follows :br 0-1mm 1-3mm 3-5mm,,0.2-0.5mm,0.1-0.5mmbr-10mesh 10-20mesh, 30-50mesh, 50-100mesh,-100mesh,-150mesh,-270mesh,br30-60mesh,60-120mesh,40-70mesh,70-140mesh,100-200mesh,br120F, 200mesh, 325mesh, 400mesh ,600mesh , 800mesh, 1250mesh,etc...brThe partice size can be produced as customer's special requirment.brFused Silica high clear Pictures:br>
