Refractory Raw Materials · Technical ManualHomogenization Bauxite
Alumina homogenized material / homogenized feedstock — a standardized, high‑end refractory raw material characterized by highly uniform composition and a dense microstructure, produced by precise ore blending, ultrafine grinding, and high‑temperature calcination of natural aluminous clay.
01Basic Definition
Natural bauxite ore Significant compositional variability and uneven impurity distribution. . Homogenized bauxite is produced by precisely blending bauxites of varying grades and fine ores, followed by fine grinding and mixing, shaping, and… High-temperature calcination at 1500°C+ Made into Highly uniform composition and dense microstructure Standardized clinker. Industry abbreviation. "Homogenized material" , Grade designations are indicated as FNJ-85, FNJ-88, and GL-88.

01Zero-fluctuation ingredientsBatch-to-batch and bag-to-bag consistency is maintained, eliminating the need for frequent adjustments to downstream formulations and significantly reducing the scrap rate.
02Higher densityBulk density: 3.25–3.42 g/cm³ (ordinary clinker: only 3.0–3.3); water absorption: 0.5%–1%; the pores are predominantly closed.
03Excellent high-temperature performanceIt exhibits excellent resistance to erosion by molten steel and slag, with superior high-temperature strength, wear resistance, and thermal shock resistance, enabling it to partially replace sub‑white corundum.
04High resource utilizationIt can digest mine‑waste bauxite powder and mixed‑grade waste ores, thereby effectively conserving high‑alumina raw ore resources.
05Easy to use and low costNo manual sorting is required; the material can be fed directly into production after crushing and screening, resulting in lower overall production costs.
05Main application areas
Refractory materials Maximum use- Unshaped refractory materials: blast furnace iron‑tapping trench castables, cement kiln castables, boiler wear‑resistant castables, ladle castables, and ramming masses.
- Shaped refractory bricks: alumina–magnesia carbon bricks, alumina–silicon carbide carbon bricks, high-alumina wear-resistant bricks, slide gates, and crucibles.
- High-temperature furnace linings: carbon black furnaces, synthetic ammonia vaporization furnaces, and heat-treatment kiln linings.
Abrasive industry- Manufactures brown fused alumina and low-iron wear-resistant abrasives, used in grinding wheels, sandblasting, and wear-resistant flooring aggregates.
Other industries- Alumina feedstock for the aluminum smelting industry
- Specialty ceramics, high-temperature physicochemical vessels, and refractory glass‑drawing components
- Wear-resistant mechanical molds, corrosion-resistant chemical pipelines, and bulletproof wear-resistant composite materials
