White Tapered Top with Cylindrical Base Zirconia Ceramic Component (For High-Precision Instruments)

Product Introduction

This product is manufactured from high-purity yttria-stabilized zirconia (Y-TZP), presenting an elegant pearl-white appearance. It features an innovative monolithic design integrating a tapered top with a cylindrical base, ensuring streamlined media guidance and providing a stable mounting reference surface. The component undergoes nano-level polishing, achieving a mirror-like finish with a surface roughness of Ra ≤ 0.1µm. This design fully leverages the unique advantages of zirconia material, including high toughness, low thermal conductivity, and exceptional wear resistance, making it specifically developed and manufactured for critical applications in high-precision instruments and fluid control systems.

Core Advantages

• Exceptional Mechanical Properties: Flexural strength ≥ 1000 MPa, fracture toughness up to 8 MPa·m¹/², 2-3 times that of conventional ceramics.

• Ultra-Low Thermal Conductivity: Thermal conductivity of 2.5 W/(m·K), effectively blocking heat transfer.

• Superior Wear Resistance: Vickers hardness HV 1300, wear rate < 1×10⁻⁷ mm³/N·m.

• Self-Lubricating特性: Friction coefficient 0.05-0.15, suitable for oil-free lubrication conditions.

• Biocompatibility: Certified per ISO 10993 for biocompatibility.

Primary Applications

• Precision Instruments: Fluid guidance components for liquid chromatographs, sample introduction systems for mass spectrometers.

• Medical Devices: Guide sleeves for dental implants, components for minimally invasive surgical instruments.

• Fluid Control: Core seats for high-precision valves, ceramic plungers for metering pumps.

• Automation Equipment: Positioning guide bushings for robotic arms, guide components for precision fixtures.

• Research Equipment: Seals for ultra-high pressure reactors, wear-resistant parts for laboratory instruments.
