Chem & Size Minerals Limited produces fused silica powder in Lianyungang, Jiangsu, China. The material is an amorphous silicon dioxide with a SiO2 purity exceeding 99.9 % and trace Al2O3 content. It is supplied as a fine powder suitable for bulk handling.
The powder is generated by electrically fusing quartz sand at 1800‑2000 °C and then grinding the resulting ingots in non‑iron ball mills to obtain a controlled particle‑size distribution. While the supplier does not list a specific mesh, the industry commonly offers grades ranging from 10 µm to 325 µm, and the product can be custom‑graded on request. The resulting powder exhibits a near‑zero linear expansion coefficient, high electrical resistivity and low thermal conductivity, properties that are standard for high‑purity fused silica. These characteristics make the material compatible with refractory, casting and semiconductor‑grade epoxy formulations.
Typical buyers include foundry operators, glass manufacturers, ceramic producers and semiconductor component makers who require dimensional stability at high temperature. The powder is normally shipped in 1‑ton bulk bags or 2‑ton supersacks, with packaging options confirmed during order negotiation. Minimum order quantities are not disclosed in the listing, so importers should request a quotation to verify MOQ and lead time. Payment terms, Incoterms and inspection arrangements are negotiated directly with Chem & Size Minerals Limited.

Chem & Size Minerals Limited is located at Haikeyinzhou, Haitang Beilu 89, Lianyungang, Jiangsu, China. The company is classified in the harbor trust tier, indicating a verified business registration, though its response rate on the platform is currently 0 %.
The firm manufactures fused silica powder and related products such as fused quartz powder using non‑iron ball‑mill technology. While the listing does not disclose production capacity, the company emphasizes high‑purity output and offers custom grading, but any claims about certifications or specific output volumes should be confirmed directly with the supplier.
Fused silica powder is a high-purity amorphous SiO2 material produced by melting selected quartz sand and processing through non-iron ball mills to achieve precise particle size distribution. Widely used in foundry, refractory, glass, ceramics, and semiconductor industries, it offers superior thermal shock resistance and low thermal expansion. As a critical industrial mineral, fused silica powder is traded globally in bulk bags or supersacks for import-export supply chains. Pricing varies by purity grade and mesh size, with long-term supply agreements common in B2B mineral trade.

Before placing an order, verify the exact SiO2 purity, particle‑size distribution and any impurity limits by requesting a recent certificate of analysis. Confirm that the supplied grade matches the performance requirements of your process, especially if the application involves high‑temperature casting or semiconductor epoxy. It is also prudent to ask for a sample batch to evaluate flow characteristics and thermal behaviour.
Logistics for fused silica powder from Lianyungang typically involve sea freight in 20‑foot containers, with the supplier favouring CIF or FOB terms. Clarify the preferred Incoterm, expected lead time and whether the supplier can arrange container loading for bulk bags or supersacks. Payment methods such as T/T against documents or LC are common in mineral trade, but the exact terms should be agreed before contract signing.
Quality control usually includes inspection of bulk density, moisture content and particle‑size analysis by sieve or laser diffraction. Arrange third‑party inspection or on‑site sampling if large volumes are ordered, and request test reports for thermal expansion and electrical resistivity. Proper documentation, including a material safety data sheet and customs import certificates, should be secured to ensure smooth clearance at the destination port.
