High Temperature Resistant 99.5% White Fused Alumina Grinding Ceramic Block: Ultimate Guide

1. Why High Temperature Resistant 99.5% White Fused Grinding Ceramic Block Al2O3 Alumina 99% Grating Plate Has Good Characteristics

This specialized alumina ceramic exhibits exceptional properties due to its ultra-high purity (99.5% Al2O3) and specialized manufacturing. The white fused alumina structure delivers unmatched thermal stability, maintaining structural integrity at temperatures exceeding 1750°C. Its extreme hardness (9 on Mohs scale) provides superior wear resistance in abrasive environments, while the fully dense, non-porous microstructure prevents particle contamination during grinding operations. The material’s chemical inertness resists acids, alkalis, and solvents, ensuring consistent performance in corrosive industrial settings. These characteristics stem from the complete transformation of raw alumina into alpha-alumina crystals during the fusion process, creating a homogeneous ceramic matrix with minimal impurities.
