Production Process


Fused Silica Product Description



Welcome to Lianyungang Chemsize International Trading Co., Ltd.



Discover our high-quality fused silica products:



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.



Raw Material


We strictly select high-purity silica sand (SiO2 > 99%) from local Donghai/Xinyi as our raw material.



Manufacturing Process


The silica sand is melted at high temperatures (2000-2300 ºC) to form amorphous silicon dioxide glassy ingots, which are then cooled. We offer fused silica lumps, sand, and powder tailored to customer requirements.

Fused Silica Product Description



Fused Silica Making Process


Fused Silica is produced using high purity crystal silica 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 not have foreign materials like string, plastic, 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, there is no MOQ, but lower quantities may incur higher costs.



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

A: We 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.
