Product Description
High Performance Silicon Nitride Ceramic Protection Tube for High Temp Furnace & Metallurgy
Silicon Nitride (Si₃N₄) Ceramic Tube / Protection Tube
Silicon nitride ceramic tube is a high-performance advanced ceramic component parts manufactured by cold isostatic pressing technology. Compared with alumina ceramic tubes, quartz tubes and ordinary metal tubes, Si₃N₄ tubes achieve a perfect combination of high temperature stability, structural toughness and chemical inertness, solving common problems such as high-temperature cracking, oxidation deformation and corrosion failure under extreme working conditions.
With rational structural design and precise machining, these ceramic tubes maintain stable mechanical and physical properties during long-term high-temperature operation and rapid temperature cycling, becoming the optimal durable solution for high-temperature protection, insulation and shielding scenarios.
Si3N4 Ceramic Parts are a man made compound synthesized through several different chemical reaction methods. they are pressed and sintered by well developed methods to produce a ceramic with a unique set of outstanding properties. The material is dark gray to black in color and can be polished to a very smooth reflective surface, giving parts with a striking appearance.
■ Superior High-temperature Stability
Supports continuous working temperature up to 1200°C and short-term extreme temperature resistance up to 1400°C. No softening, deformation or structural failure under long-term high-temperature service, far exceeding metal and ordinary ceramic tubes / pipes.
■ Excellent Thermal Shock Resistance
Outstanding resistance to rapid heating and cooling. The integrated dense sintered structure effectively resists temperature impact, avoiding cracking and peeling caused by thermal stress, greatly improving service life in cyclic temperature working conditions.
■ High Fracture Toughness & Structural Strength
Higher bending strength and impact toughness than traditional oxide ceramics. It is not easy to crack or break under vibration, pressure and mechanical impact, ensuring stable structural support and protection performance.
■ Excellent Corrosion & Erosion Resistance
Inert chemical property, resistant to most acids, alkalis, high-temperature flue gas and molten metal erosion. No chemical precipitation or pollution, suitable for high-purity production and harsh corrosive environments.
■ Good High-temperature Insulation & Low Expansion
Reliable electrical insulation performance at high temperature. Low thermal expansion coefficient ensures stable tube size and fitting accuracy during temperature changes, avoiding loose fitting and failure.
Main Applications:
High-temperature furnace protection tubes, thermocouple insulating sleeves, metallurgical molten metal conveying and shielding tubes, semiconductor thermal processing equipment, new energy high-temperature modules, chemical anti-corrosion piping and industrial high-temperature insulating structural parts.
