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 fused silica a versatile material for refractory applications, such as in aluminum launders or other highly cyclical applications.


At Lianyungang Chemsize International Trading Co., Ltd., we carefully select high purity silica sand (SiO2 > 99%) from 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 processed into fused silica lump, sand, and powder based on customer requirements.

Fused Silica Product Description



Fused Silica Making Process


Fused Silica is produced from high-purity crystal silica sourced from China Donghai-Xinyi. It is electrically fused at temperatures ranging from 1800-2000ºC to create amorphous Silicon dioxide. The resulting material is engineered into various forms such as lumps, cullet, ingots, sand, grain, granular, and powder flour. These forms are specifically designed for manufacturing PV fused silica crucibles, thermal ceramics, refractories, EMC investment casting ceramic shells, and more.



Fused Silica Sand Appearance and Specifications:



  • Must not contain any unfused parts

  • Should be free of foreign materials such as strings, plastic lines, carbon, wood, metal, or other contaminants

  • Only conditional black dots are allowed

  • Black spot diameter should not exceed 2mm

  • Total black dots quantity should be less than 10 per square meter



FAQ:


Q1. Can I request a sample order for fused silica products?

A: Yes, we offer free samples shipped via ***/FEDEX/DHL. Mixed samples are also acceptable.



Q2. What is the lead time for samples?

A: Samples are typically sent within 3-5 days.



Q3. Is there a minimum order quantity for fused silica sand?

A: No, but lower quantities may result in higher average costs.



Q4. How are the goods shipped and what is the delivery time?

A: We usually ship via DHL, UPS, FedEx, or *** with an average delivery time of 3-5 working days. Sea shipments may take 7-40 days depending on the distance.
