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

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.

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?

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!
Fused silica introduce :
 
Fused silica is made of high purity crystal silica by electrically fusing (fusing temperature 1800-2000ºC) to amorphous Silicon dioxide , then they are classed to different grades by manual and then specially engineered to granular and powder form. Because fused silica has a very low thermal conductivity and excellent thermal shock resistance, it is used in lots of fields of investment casting,refractory,ceramic,epoxy modling compound,fusion bounded epoxy.
 

Fused silica application:
Refractory, ceramic, investment casting, foundry, epoxy molding compound, fusion bounding epoxy powder coating.
