Superior Strength And Toughness With Silicon Nitride Ceramics For High-Performance Applications

Product Overview

This product is a precision-engineered polygon-shaped structural plate manufactured from high-performance Silicon Nitride Ceramic. It features a deep black color with a fine, matte texture and an extremely dense microstructure, highlighting its superior physical properties. Silicon Nitride is an advanced engineering ceramic renowned for its exceptional strength, outstanding thermal shock resistance, superior wear resistance, and excellent chemical corrosion resistance, making it ideal for demanding industrial environments. The chamfered edges and mounting holes at the corners reflect a user-centric design focused on safety and easy installation.

Key Features & Advantages

• High Strength & Toughness: Possesses a fracture toughness significantly higher than most technical ceramics, enabling it to withstand high loads and impacts, reducing the risk of brittle fracture and extending service life.

• Excellent Thermal Shock Resistance: Capable of withstanding rapid temperature changes exceeding 1000°C without cracking, ensuring reliable performance under thermal cycling.

• Superior Corrosion Resistance: Highly resistant to attack by most acids, alkalis, and molten metals, making it suitable for harsh chemical environments.

• Low Density & High Hardness: Lighter than steel yet exceptionally hard, offering an ideal combination of lightweight design and superior abrasion resistance.

• Excellent Electrical Insulation: A superb electrical insulator, guaranteeing safety in high-temperature and high-voltage applications.

Typical Applications

• Precision Machinery & Automation: High-precision measurement instrument platforms, robotic structural supports, linear guideway sliders.

• Semiconductor Industry: Clamps, chucks (ESK), and insulating baffles in semiconductor diffusion and etching processes.

• High-Temperature Equipment Protection: Viewport covers for kilns, protective panels for heat treatment equipment, thermal insulation shields for instruments.

• Chemical & Energy Industry: Mechanical seal rings for pumps, valve components, corrosion-resistant lining plates.

Usage Instructions

1. Installation & Fastening: Use metal fasteners (e.g., stainless steel) with a matching coefficient of thermal expansion. Apply appropriate preload force; avoid over-tightening to prevent fracturing the ceramic plate.

2. Surface Protection: Despite its high hardness, avoid sharp impacts with hard objects during handling and installation to prevent surface damage.

3. Environmental Compatibility: While highly chemical-resistant, prolonged exposure to hydrofluoric acid or hot, concentrated phosphoric acid should be avoided.

4. Cleaning & Maintenance: Clean with a neutral detergent and a soft cloth to maintain surface cleanliness.
