ALUMINUM OXIDE STD-A25
Product Benefits
STD-A25 portfolio offers a wide range of refractory agglomerated super-calcined (RASC) bauxite, which has been calcined at 1650 °C to a high-density aluminum oxide. The main constituent is the mineral corundum.
Quality assurance: Standardized quality guaranteed through ISO 9001 certified quality management.
Process control: Raw materials and production are closely monitored to ensure consistent chemical composition and grain size.
Applications: Used as a raw material for welding fluxes, in refractories, and in slip- and wear-resistant floorings.
