*Pan designates the percentage of fused silica passing the last reported screen for each size.Fused silica production process
We strictly choosed the high purity silica sand (SiO2>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.

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 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 andSpecifications:

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 dots

4): 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 per
square meters
