The right lining material defines industrial reliability—especially in extreme conditions. Alumina lining bricks, engineered with 75–99.99% Al₂O₃ content, have become the go-to choice across key sectors, solving pain points traditional liners can`t address. From high-heat cement kilns to corrosive chemical plants, their versatile applications deliver unmatched value where performance matters most. Explore their transformative impact in five core industries.
Cement Manufacturing
Rotary kilns and preheaters face 1400°C+ temperatures, abrasive clinker, and alkaline attack. Alumina bricks (85–95% Al₂O₃) offer Mohs hardness 9 and high refractoriness, resisting wear and reducing heat loss by 25–30%.
Mining & Mineral Processing
Ore, gravel, and slurries quickly degrade steel equipment. Alumina liners (90%+ Al₂O₃) provide 10–20x the wear resistance of manganese steel, ideal for pipelines, ball mills, and chutes. They reduce media consumption by 30% and prevent product contamination, key for high-purity minerals. A South American copper mine extended slurry pipe life from 3 months to 4 years, eliminating monthly replacement costs and unplanned shutdowns.
Power Generation
Thermal, biomass, and waste-to-energy plants need liners that withstand high heat, flue gases, and ash erosion. Alumina bricks resist 500°C+ thermal shocks and corrosive SOx/NOx, outperforming alloy steel.
Chemical & Petrochemical Industry
Aggressive acids, alkalis, and molten salts destroy conventional liners. Ultra-pure alumina bricks (99%+ Al₂O₃) are chemically inert, withstanding 98% sulfuric acid and 50% sodium hydroxide.
Semiconductor & High-Tech
Ultra-pure (99.99% Al₂O₃) alumina bricks enable contamination-free semiconductor manufacturing. Non-porous and non-reactive, they prevent metal ion leaching, keeping wafer metal content below 1ppm for 7nm/5nm chips.
Across all applications, alumina lining bricks deliver long-lasting, cost-effective protection that drives operational excellence. Their adaptability to heat, abrasion, corrosion, and contamination makes them a smart investment for reducing costs and maximizing productivity.
