High Toughness Zirconia Ceramic Flange Gasket with Excellent Wear Resistance and Ultra-precise Dimension Control

Product Introduction

This product is a disc-type perforated zirconia ceramic flange gasket, fabricated from high-purity zirconia (ZrO₂) powder via dry pressing, high-temperature sintering and CNC precision grinding. Designed as circular flange structure with evenly spaced mounting holes and central hollow bore, it features high density and ultra-smooth compact surface. Benefiting from phase transformation toughening property of zirconia material, it combines high strength, outstanding fracture toughness and superior wear & chipping resistance, serving as specialized ceramic component for sealing, positioning and wear prevention on precision industrial equipment.

Application Fields

Widely applied in automation machinery, precision motors, semiconductor equipment, lithium-ion battery production equipment and pump & valve assemblies. It works as mounting flange spacer, wear-resistant limit washer, insulating sealing gasket for positioning fixation, anti-friction buffering, corrosion isolation and pressure sealing.

Core Advantages

  1. High Toughness & Impact Resistance: Far higher toughness than alumina ceramics, resistant to edge chipping and cracking under alternating impact loads;
  2. Excellent Wear & Corrosion Resistance: Low friction coefficient, stable against acid, alkali and salt erosion for long service life under harsh chemical environments;
  3. Ultra-precise Dimension Control: Tolerance of outer diameter and mounting holes within ±0.01mm for perfect assembly fitting;
  4. Low Thermal Expansion & Insulation: Minimal thermal deformation under fluctuating temperature, reliable electrical insulation to avoid leakage risk.

FAQ

Q: What are advantages of zirconia gasket vs alumina gasket?
A: Zirconia owns superior toughness and anti-break performance, its service life is 2~3 times longer than alumina, ideal for frequently vibrating working conditions.
Q: Can we customize the number of mounting holes?
A: Yes, hole diameter, hole layout and disc thickness can be customized as your requirement.
