Fused Silica

Product Description: Fused Silica is a high-quality material with exceptional properties, making it ideal for various industrial applications. It is produced by carefully controlling the particle size distribution and maintaining a consistent chemistry. With an extremely low coefficient of thermal expansion, Fused Silica offers excellent thermal stability.

Applications: Fused Silica finds extensive use in industries such as thermal ceramic, refractory, investment casting, EMC, solar crucible, quartz marble, and powder coating. Its versatility makes it suitable for a wide range of applications.

Particle Sizes: Fused Silica is available in various particle sizes to meet different requirements. The sizes include 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, and 1250mesh. Custom particle sizes can also be produced as per customer's specific requirements.

Production Process

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 local Donghai/Xinyi 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 lump, sand, and powder according to our customers' requirements.

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.
