High Precision ZrO2 Zirconia Ceramic Piston

Design Features

Excellent material properties

High-purity zirconium oxide (more than 95%): hardness ≥1200HV, wear resistance far exceeds that of metals and ordinary ceramics.

Low friction coefficient: surface polishing to Ra≤0.1μm, reducing medium adhesion and extending the life of seals.

Precision machining technology

Nano-level precision: diameter tolerance ±0.01mm, suitable for high-precision fluid control.

Diversified structure: supports flat head, cone, multi-step design, etc., suitable for different pump body requirements.

Environmental adaptability

Corrosion resistance: acid and alkali resistance, organic solvent resistance, suitable for extreme environments with pH 1-14.

High temperature resistance: working temperature can reach 800℃ (partially stabilized formula).

Enhanced design

Fracture toughness resistance: through yttrium stabilization treatment (Y-TZP), bending strength ≥1000MPa.

Lightweight: density 6.0g/cm³, 60% lighter than metal plunger, reducing equipment energy consumption.
