High Cleanliness And Corrosion Resistance With Silicon Nitride Ceramics For Chemical Industry Tools

High Cleanliness And Corrosion Resistance With Silicon Nitride Ceramics For Chemical Industry Tools

Product Overview
This product is a precision-engineered mechanical component manufactured from high-performance silicon nitride (Si₃N₄) ceramic, comprising a square-ring handle and a flat, elongated latch. It exhibits the characteristic dark gray to black color of silicon nitride, with a uniform texture and smooth, functional finish free of embellishments, embodying a minimalist and purpose-driven industrial design. This assembly leverages the exceptional strength, outstanding wear resistance, and superior thermal stability of silicon nitride ceramic, specifically designed for reliable connection, actuation, or positioning in demanding applications.

Primary Applications
Due to its superior mechanical properties, this component is suitable for various high-demand scenarios:

• High-Performance Mechanical Links: Used as manual operating handles and locking pins in semiconductor equipment or high-temperature furnaces requiring frequent operation or precise positioning, offering high-temperature and corrosion resistance.

• Precision Instrument Components: Serves as insulating, non-magnetic adjustment knobs, fixture pins, or guide components in measuring and analytical instruments, ensuring accuracy is unaffected by electromagnetic fields or thermal variation.

• Special Environment Tooling: Ideal for tools in chemical or medical industries requiring high cleanliness and corrosion resistance, used as operating levers or connection pins.

• Wear-Resistant Transmission Parts: Can function as part of linkage mechanisms in automation equipment, providing lightweight and wear-resistant performance.

Key Advantages

• Exceptional Strength & Hardness: High hardness (HRA ≥92) and very high flexural strength enable it to withstand heavy loads and impact, with a lifespan far exceeding metals.

• Superior Wear & Corrosion Resistance: Offers excellent abrasion resistance and withstands most acids and alkalis, with minimal risk of wear particle contamination.

• Excellent Thermal Stability: Low coefficient of thermal expansion and exceptional thermal shock resistance allow it to maintain shape and properties at temperatures exceeding 1200°C.

• Lightweight & Self-Lubricating: Significantly lower density than steel enables lightweight design; possesses a degree of self-lubrication for smoother operation.

• Insulating & Non-Magnetic: An excellent electrical insulator and non-magnetic, suitable for sensitive electronic or strong magnetic field environments.

Manufacturing Process
Raw material mixing (High-purity Si₃N₄ powder & sintering aids) → Forming (Pressing / Isostatic Pressing) → Machining (Green body pre-machining) → High-Temperature Sintering (Reaction Sintering or Hot Pressing) → Precision Grinding & Polishing (Achieving final dimensions & finish) → Non-Destructive Testing (Dimensions, flaws) → Packaging.

Usage Instructions

1. Installation & Operation: When installing the latch, align it properly with the hole and avoid direct impact with metal hammers. Use nylon or copper tools for assistance. Operate the handle with even force, avoiding excessive torque or lateral impact on the ring handle.

2. Fit and Clearance: Design appropriate clearance with metal parts based on differences in thermal expansion coefficient and operating temperature.

3. Avoid Hard Impact: Although silicon nitride is relatively tough, it remains a brittle material. Prevent dropping or severe collision with hard surfaces.

Frequently Asked Questions (FAQ)

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

  • A: Silicon nitride generally outperforms zirconia in high-temperature strength retention, thermal shock resistance, and hardness, making it more suitable for extreme temperatures and frequent thermal cycling. Zirconia typically offers higher fracture toughness at room temperature.

• Q: Can the dimensions of this handle and latch be fully customized?

  • A: Yes. We support custom manufacturing and can design and produce components with specific dimensions, shapes (e.g., round, polygonal handles), and connection methods based on your assembly requirements.

• Q: Is this component suitable for use in strong acid or alkali environments?

  • A: While silicon nitride offers excellent corrosion resistance against most acids and alkalis, it can be corroded in specific extreme environments like hot concentrated alkalis or hydrofluoric acid. Please confirm the specific operating media in advance.
