Product Description
Custom Zirconia Ceramic Washer High Hardness Anti‑Corrosion Slotted ZrO2 Seal Spacer Gasket
Zirconia (ZrO₂) ceramic structural parts are advanced precision engineering ceramics manufactured from high-purity zirconia powder with stabilizers such as yttria, through dry pressing, isostatic pressing and high-temperature sintering. Known as “ceramic steel”, zirconia ceramics stand out among structural ceramic materials for their exceptional toughness, ultra-high strength and outstanding wear resistance, widely used for precision structural components under harsh mechanical and thermal working conditions.
Zirconia ceramic washers (ZrO₂ washers) are precision‑manufactured annular ceramic spacers & sealing gaskets made from high‑purity yttria‑stabilized zirconia raw material. Produced via isostatic pressing, high‑temperature sintering and ultra‑precision grinding, these ceramic washers deliver outstanding mechanical strength, toughness and chemical inertness. They serve as spacing, sealing, wear‑resistant and insulating components, widely replacing metal, PTFE and ordinary alumina washers under harsh working conditions. Ideal for pumps, valves, chemical processing equipment and precision machinery to reduce friction wear and resist chemical medium erosion.
Zirconia ceramic is known as “ceramic steel” for its excellent comprehensive mechanical properties, making our zirconia rotors irreplaceable in high-speed and high-toughness application scenarios:
-
High Fracture Toughness: Known as “ceramic steel”, yttria‑stabilized zirconia avoids brittle chipping under impact and cyclic pressure, far superior to alumina ceramic.
Excellent Wear Resistance & Low Friction: High surface hardness with fine ground smooth surface, low friction coefficient. Long‑term cyclic friction without dimension loss, extending equipment service life.
Superb Chemical Corrosion Resistance: Inert to most acids, alkalis, salt solutions and organic solvents. No rust or chemical dissolution, perfect for corrosive slurry and chemical fluid environments.
High‑Dense Pore‑Free Structure: Dense microstructure prevents medium penetration and contamination, satisfying high‑purity production requirements for pharmaceutical, new‑energy slurry processing.
Stable Dimensional Performance: Low thermal expansion coefficient, minimal deformation under temperature fluctuation. Tight tolerance ensures consistent fitting and sealing performance.
Electrical Insulation Property: Good insulation performance, suitable for equipment requiring electrical isolation.
