Feature Listing for High Purity Polishing Silicon Nitride Ceramic Balls (Si3N4 Balls)
Ultra-High Purity Material – Precision-crafted from 99.9% pure silicon nitride (Si3N4) for exceptional chemical inertness and thermal stability. Medical-Grade Smoothness – Mirror-polished surface (Ra <0.02μm) minimizes friction in dental handpieces, ensuring ultra-quiet operation and extended lifespan. Extreme Durability – Superior hardness (Hv 1500+) and fracture toughness resist chipping or wear under high-speed rotations. Biocompatible & Sterilizable – Ideal for dental/surgical tools; withstands repeated autoclaving (up to 180°C) without degradation. Precision Engineering – Tight tolerance (±0.001mm) guarantees balanced performance in high-RPM applications like turbine drills. Multi-Industry Use – Also perfect for aerospace bearings, precision pumps, and semiconductor equipment. Bulk Discount Ready – Global wholesale pricing with MOQ flexibility for clinics, labs, and manufacturers.
