High-quality alumina ceramic polishing stones, alumina ceramic for polishing, excellent quality.

The specifications of high-alumina porcelain mainly range from Φ1 to Φ70mm, available in both rolling molding and isostatic pressing molding. Key performance indicators include: Al₂O₃ content >92%, density >3.60 g/cm³, equivalent wear <0.08‰ (Φ2–15), and equivalent wear <0.12‰ (Φ20–60). It features low wear, high strength, corrosion resistance, high specific gravity, stable product quality, and a glossy appearance, making it widely applicable in construction ceramics, specialty ceramics, refractory materials, chemical engineering, and hardware industries. Compared to natural stone balls and ordinary ceramic balls, its wear resistance is improved by 20–40 times, grinding efficiency increases by 40–60%, mill efficiency rises by 30–40%, overall costs are reduced to 40–60% of those of natural stone balls, and the service life of mills extends from 2 years to 6–8 years.
