Fused silica production process

Fused silica is high purity quartz sand that has been melted to form glass. High volume stability, low volumetric expansion and high purity make fused silica a very useful and versatile material for refractory applications, whether in aluminum launders or other highly cyclical applications.
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,

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 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

FAQ:
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.

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!


Chem&Size minerals 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 castables
