Fused Silica Production Process
Fused Silica Production Process
Fused silica is a high purity quartz sand that has been melted to form glass. Its high volume stability, low volumetric expansion, and high purity make it a very useful and versatile material for refractory applications, such as aluminum launders or other highly cyclical applications.
At Lianyungang Chemsize International Trading Co., Ltd., we strictly choose high purity silica sand (SiO2 > 99%) from the local Donghai/Xinyi area as our raw material. The silica sand is melted at high temperatures (2000-2300 ºC) to form an amorphous silicon dioxide glassy ingot, which is then cooled. We further process the products into fused silica lumps, sand, and powder according to our customers' requirements.
Discover our high-quality Fused Silica for Foundry applications. Our Quartz Foundry products, including Fused Quartz Grains and Quartz Powder, are perfect for investment casting and refractory purposes. As a leading Fused Silica manufacturer and Quartz Sand supplier, we provide top-notch materials for your casting needs.

Fused Silica Making Process
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. It is then specially engineered into lumps, cullet, ingots, sand, grain, granular, and powder flour form. These forms are designed for making PV fused silica crucible, thermal ceramic, refractory, EMC investment casting ceramic shell, and more.
Fused Silica Sand Appearance and Specifications:
- It is forbidden to contain any unfused parts.
- It is forbidden to have foreign material, such as string, plastic line, carbon or wooden material, metal, or other outside contaminants.
- All color dots are forbidden except conditional black dots.
- Black spot diameter larger than 2mm is not acceptable.
- Total black dots quantity should be less than 10 when opening the big bag, equal to or less than 10 dots per square meter.
FAQ:
Q1. Can I have a sample order for fused silica products?
A: Yes, we'd like to send samples free of charge by ***/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 deliver orders for quantities 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 ***. It usually takes 3-5 working days to arrive. It depends on the distance by sea, which can take 7-40 days.
Q5. How to process an order for fused silica powder products?
A:
- Let us know your requirements or application.
- We quote according to your requirements or our suggestions.
- Customer confirms the samples and pays a deposit for the formal order.
- 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 based on our sample.
Q7: How to deal with the faulty?
A: Firstly, our products are produced in a strict quality control system, and the defective rate will be less than 0.2%. Secondly, if it happens, we shall arrange to send new products to you and pay for all your losses.
