Silicon Nitride Ceramic Bracket For High-Temperature Furnaces — Features Cylindrical Base And Square Boss To Prevent Rotation
Product Overview
This product is manufactured from high-performance reaction sintered silicon nitride ceramic, presenting a dark gray metallic luster with dense and uniform material texture, exhibiting a unique corundum-like质感. It features an integrated design combining a cylindrical base with a square boss, penetrated by a high-precision central through-hole. The overall dimensions are precise with smooth chamfered edges. This structure ingeniously combines the stability of cylindrical forms with the anti-rotation特性 of square shapes, fully leveraging the excellent properties of silicon nitride ceramic, making it an ideal connecting component for harsh conditions such as high temperature and corrosive environments.
Primary Applications
Bearing seats and connecting components for transmission devices in high-temperature kilns
Corrosion-resistant and wear-resistant connecting brackets for chemical pumps and valves
Insulating structural supports in semiconductor equipment
High-precision positioning modules in automation equipment
Corrosion-resistant structural components in medical devices
Key Advantages
Hardness up to HRA92+, wear resistance 10 times better than tool steel
Temperature resistance up to 1300°C (in oxidizing atmosphere), with low thermal expansion coefficient of 3.2×10⁻⁶/°C
Resistance to acid and alkali corrosion (except hydrofluoric acid), suitable for chemical environments
Specific gravity of only 3.2g/cm³, enabling lightweight design
Friction coefficient of 0.1-0.3, featuring self-lubricating properties
