Zirconia Ceramic Ball Teeth Product Introduction:
Zirconia ceramic ball teeth are industrial products made from zirconia (ZrO₂) as the base material, usually with the addition of stabilizers such as yttrium oxide (Y₂O₃) to improve thermal stability. This product possesses high density, high hardness, and excellent wear resistance, and is widely used in various industrial fields.
Performance Characteristics
1. Wear Resistance: The wear rate is 40% lower than that of steel balls under high-speed grinding conditions, with a Vickers hardness of >1200 kg/mm².
2. High Impact Resistance: Crushing strength exceeds 150 kgf, capable of withstanding mechanical impact during high-speed operation of grinding mills.
3. Thermal Stability: The thermal expansion coefficient is close to that of metal materials (10.0 × 10⁻⁶/K), reducing thermal stress damage.
4. Surface Characteristics: The pearlescent surface reduces material adhesion, and maintains a uniform wear pattern even after wear.
Application Fields
1. Mining Machinery: Used in wear-resistant components for equipment such as crushers and ball mills.
2. Construction Industry: Wear-resistant components for concrete mixing equipment and stone processing machinery.
3. Precision Machining: Ultra-fine grinding of titanium alloys and ceramic matrix composites in the aerospace field.
4. Chemical Production: Titanium dioxide dispersion and wet grinding of polymer materials.
5. Electronics Manufacturing: Polishing and dispersion of optical connector components.
