Calcined Bauxite Lumps supplied by USJ Refractories Pvt Ltd are produced by heating raw bauxite ore above 1700 °C, resulting in a material with an aluminium‑oxide (Al₂O₃) content ranging from 85 % to 95 % and a hardness that supports high‑temperature applications. The lumps are offered in various sizes and are designed to meet the strict performance requirements of steelmaking, cement, ceramics and foundry industries. The supplier highlights the product’s superior thermal stability and durability under harsh conditions.
Typical industry practice for calcined bauxite lumps includes a particle‑size range of 10 mm to 30 mm, a bulk density of 1.4‑1.6 g/cc and a moisture content below 0.5 %, all of which are marked as typical values for this commodity. Hardness on the Mohs scale is usually between 8 and 9, providing the wear resistance needed for refractory brick and castable manufacturing. These specifications are consistent with standard refractory‑grade bauxite used worldwide.
Primary buyers are manufacturers of refractory bricks, castables and anti‑skid railway track components who require reliable alumina‑rich material. The listing mentions that FOB and CIF shipping options are available, but exact pricing and minimum order quantities are not disclosed and should be confirmed with the supplier. Importers are advised to verify certifications, size distribution and delivery terms before finalising a purchase.

Before placing an order, importers should request the latest analysis report confirming the aluminium‑oxide content and particle‑size distribution of the calcined bauxite lumps. Because the listing shows no recorded response rate, it is prudent to verify the supplier’s communication speed and ability to provide sample material. Confirm that the product complies with any project‑specific refractory standards and that the supplier can supply the required lump size.
Shipping is offered on FOB or CIF terms, but the exact port of loading and freight responsibilities must be agreed in advance. Buyers need to ask the supplier for an estimated lead time, which can vary with production schedules and export documentation. Payment conditions such as a bank‑confirmed LC or advance transfer should be clarified before contract signing.
A third‑party inspection before loading can verify bulk density, moisture level and hardness against the typical values stated. Request the supplier’s ISO and SGS certificates, as well as a mill test report, to support quality assurance. Retaining these documents will simplify customs clearance and downstream quality control.
