Product Description

Product Description

Calcined Bauxite is produced from high-grade bauxite ore sintered in a rotary kiln at 1500-1800°C, featuring stable chemical composition and high mechanical strength. With Al2O3 content of 85%-90% and refractoriness above 1770°C, it is the ideal raw material for refractory castables, high alumina bricks, abrasives and cera

Features

Rotary Kiln Calcined — Sintered at 1500-1800°C for complete phase transformation, ensuring stable density and low water absorption.
High Al2O3 Content — 85%-90% grades available, with refractoriness above 1770°C for high-temperature service.
Consistent Quality — Every batch tested for chemical composition and physical properties, COA shipped with goods.
Multiple Grain Sizes — 0-1mm, 1-3mm, 3-5mm, 5-8mm aggregates and 200 mesh powder for different formulations.
Excellent Performance — High thermal stability, good abrasion resistance, low impurity content.

Applications

Refractory Castable— key aggregate for low-cement and conventional castables
High Alumina Brick— main raw material for Al2O3 55-90% brick grades
Abrasive Industry— blasting media and grinding materials
Ceramic Raw Material— ceramic proppant, mullite and cordierite production
Steel / Cement / Glass Kilns— furnace lining applications
