Quartz lumps

Sainsu Minerals supplies quartz lumps that consist of high purity silica quartz with a minimum SiO2 content of 99.6 % as stated in the listing. The product is delivered in bulk metric‑ton loads and is packed in standard 20‑foot containers for efficient ocean freight. Each lump is an irregular natural form suitable for bulk handling without further processing. The supplier notes that the material meets common grade specifications required for industrial use.

In the mineral market, quartz lumps are typically offered with particle sizes between 5 mm and 30 mm, a range that balances flowability and surface area for glass and ceramic furnaces. The bulk density of silica quartz is typically around 2.6 t/m³, which influences container loading calculations. Impurities other than silica are usually limited to less than 0.4 % in industrial grade material, ensuring consistent performance in high‑temperature processes. These typical parameters align with standards such as ASTM C618 for natural sand used in construction, although specific certification should be confirmed with the supplier.

Primary buyers include glass manufacturers, foundries, ceramic producers and ferro‑alloy plants that require consistent silica content for melt stability. Sainsu Minerals ships the lumps on a container‑load basis, and while the listing does not disclose exact minimum order quantities, interested importers should request the required MOQ and preferred Incoterms from the supplier. Payment terms are not detailed in the public data, so buyers need to negotiate terms such as T/T or L/C before dispatch. Confirming packaging details, loading plans and any required quality documentation will help streamline the sourcing process.
