Calcined Flint Clay
Calcined Flint Clay from Kaifeng Datong Refractories Co., Ltd is a fireclay material calcined at high temperatures to deliver thermal stability and low porosity. The Al2O3 content is specified at 35-50 percent, a range that positions this clay as a reliable raw material for refractory applications where consistent performance under heat is critical. Sourced from China’s Henan province, it is supplied in bulk packaging to meet industrial-scale demand for refractory brick production and furnace linings.
The clay’s mineral composition is primarily kaolinite-derived, with the calcination process enhancing its resistance to thermal shock and chemical corrosion. Typical particle sizes for refractory-grade flint clay range from fine to coarse fractions, depending on the end use, with standard tolerances for moisture content below 1 percent and iron oxide levels under 2 percent. These parameters ensure compatibility with advanced ceramic and glass manufacturing processes, where uniformity is essential.
Industries such as steelmaking, glass furnace construction, and ceramic production rely on this material for its durability in extreme environments. Buyers in these sectors source it in bulk, often under FOB terms from Chinese ports like Tianjin or Qingdao, with packaging designed to prevent moisture reabsorption during transit. Confirming the exact particle size distribution and bulk density with the supplier is recommended to match specific application requirements.

Sourcing Calcined Flint Clay from Kaifeng Datong Refractories Co., Ltd - China Import Guide
Before ordering, verify the Al2O3 content and particle size distribution to ensure compatibility with your refractory or ceramic application. Request a certificate of analysis from Kaifeng Datong Refractories Co., Ltd to confirm these specifications, as variations can impact performance in high-temperature environments.
Logistics details such as lead time, Incoterms (e.g., FOB Tianjin), and payment terms should be clarified with the supplier. Bulk shipments typically require coordination for port handling and moisture protection. Confirm whether the supplier can provide CIF terms for door-to-door delivery if needed.
Quality checks should include testing for bulk density, porosity, and chemical composition using standard methods like ASTM or ISO. Inspect the material upon arrival for moisture content and particle consistency. Request documentation such as MSDS and test reports to ensure compliance with your industry’s quality standards.
