Silicon Nitride bonded Silicon Carbide Kiln Furniture [MH-LNY-Sinsic KF1]
Product Features
Introducing our high-performance Silicon Nitride Bonded Silicon Carbide (Si₃N₄-SiC) kiln furniture, specifically designed for high-temperature industrial applications:
- Exceptional Thermal Shock Resistance: These components provide outstanding resistance to rapid temperature changes, ensuring long service life even in harsh thermal environments.
- High Strength and Durability: With a cold crushing strength of ≥140 MPa and a high-temperature flexural strength of ≥40 MPa at 1400°C, they deliver excellent mechanical stability under load.
- Wear Resistance: Excellent wear resistance makes them suitable for prolonged use in high-wear environments such as kilns and furnaces.
Applications
Silicon Nitride Bonded Silicon Carbide kiln furniture is ideal for:
- Kiln Shelves and Pillars: Widely used in ceramic, electrical porcelain, and grinding wheel firing kilns.
- Saggers and Push Plates: Suitable for high-temperature applications in powder metallurgy and electronics industries, providing stability and durability during heat treatment.
Technical Highlights
- High Refractoriness: The refractoriness under load is ≥1700°C, making it ideal for high-temperature kilns where stability and heat resistance are critical.
- Efficient Thermal Conductivity: At 1000°C, these materials offer a thermal conductivity of 17 W/m•K, ensuring effective heat transfer and reducing energy consumption.
- Low Open Porosity: With an open porosity of ≤18%, the materials maintain structural integrity and resist contamination during use.
