High-Performance Zirconia Ceramics Ideal For Precision Guidance High-Temperature Fluid Control And More

Product Overview
This product is a high-precision cylindrical rod manufactured from yttria-stabilized zirconia (YTZP) ceramic. Characterized by its minimalist design, it features a smooth, untextured slender shaft with a precision-machined circular boss at one end, exhibiting the characteristic ivory-white color and mirror-like finish of advanced ceramics. Engineered to leverage the exceptional physical and chemical properties of zirconia, this component is specifically designed to withstand demanding conditions including high wear, elevated temperatures, and corrosive environments. It is an ideal critical component for enhancing the reliability, service life, and stability of precision equipment.

Primary Applications
Thanks to its unique combination of properties, this component is ideally suited for:

• Precision Guidance & Transmission: Used as linear guide rails, guide rods, or bushings in automation equipment and precision measuring instruments, ensuring low-friction, high-accuracy movement, even without lubrication.

• High-Temperature Fluid Control: Serves as a valve core, metering pump plunger, or critical component in chemical processes, offering corrosion and wear resistance for long-term sealing stability.

• Sensing & Measurement: Acts as sensor probes, insulating sleeves, or measuring rods in harsh environments, providing excellent electrical insulation and chemical inertness.

• Semiconductor & Medical Equipment: Employed in wafer handling and medical devices where high purity and corrosion resistance are paramount.

Key Advantages

• Exceptional Wear Resistance: Extreme hardness (HRA ≥88) results in wear resistance far superior to metals, significantly reducing maintenance cycles and replacement costs.

• Excellent High-Temperature Stability: Capable of operating continuously at temperatures up to 800°C, with low thermal expansion for outstanding dimensional stability.

• Superior Chemical Corrosion Resistance: Resists attack from most acids, alkalis, and salts, making it suitable for complex chemical environments.

• High Strength & Toughness: Transformation toughening provides high flexural strength and fracture toughness, offering good resistance to mechanical shock.

• Low Friction & Self-Lubricating Properties: The smooth surface ensures a low coefficient of friction for smooth operation and reduced power loss.

• Excellent Electrical Insulation: Non-conductive, ideal for precision electronic and sensing applications requiring insulation.

Manufacturing Process
The component undergoes a strict manufacturing process to ensure quality: Raw Material Preparation (High-Purity Zirconia Powder) → Forming (Isostatic Pressing/Injection Molding) → Green Body Machining → High-Temperature Sintering (>1500°C) → Precision Grinding → Ultra-Fine Grinding/Polishing → Comprehensive Quality Inspection (Dimensions, Appearance, Performance) → Clean Packaging.

Usage Instructions

1. Installation Precautions: Use non-metallic tools (e.g., nylon hammer, copper rod) for installation. Avoid impact, collision, or applying improper bending stress to prevent brittle fracture.

2. Fitting and Alignment: When assembling with metal parts, allow for appropriate thermal expansion clearance and ensure proper alignment of mounting holes to avoid assembly stress.

3. Environmental Suitability: Although it offers excellent corrosion resistance, consult technical advisory for suitability confirmation before use in specific extreme chemical media (e.g., hydrofluoric acid, hot concentrated alkalis).

Frequently Asked Questions (FAQ)

• Q: What are the maximum achievable length and diameter for this ceramic rod?

  • A: Dimensions are constrained by sintering technology. Excessively high length-to-diameter ratios increase manufacturing difficulty. Please provide drawings for specific requirements, and we will assess feasibility.

• Q: What are the advantages of Zirconia Ceramic compared to Silicon Nitride Ceramic?

  • A: Zirconia (YTZP) generally offers superior fracture toughness and flexural strength at room temperature and excellent wear resistance. Silicon Nitride typically maintains better strength and thermal shock resistance at very high temperatures (>1000°C). The choice depends on the specific application conditions.

• Q: Can the boss be machined into a non-circular shape or with threads?

  • A: Customization is possible. We support non-standard designs; however, complex shapes (like internal threads) require structural strength evaluation and may have limitations.
