Thermocouple Protection Silicon Nitride Bush Si3n4 Ceramic Shaft Sleeves¹

Product Description Product DescriptionSilicon Nitride is a chemical compound of silicon and nitrogen. It is a hard ceramic and is mostly used in high-endurance and high-temperature applications.Silicon nitride ceramic material Introduction: Silicon nitride is an inorganic substance with the formula Si3N4. It is an important structural ceramic material, high hardness, itself has lubricity, and wear resistance, atomic crystal; Antioxidant at high temperatures. Moreover, it can also resist cold and thermal shock, heated to more than 1000 ° C in the air, sharply cooled and then sharply heated, and will not crumble.Features of Silicon Nitride Tube :1. Good density, high strength.2. Excellent thermal conductivity and thermal impact resistance.3.and aluminum melt and other non-ferrous metal melt non - wetting, corrosion resistance.4. High temperature resistance and low thermal expansion coefficient. Product Parameters Property SSNGPS-SSNHPSNRBSNDensity (g.cm-3) 3.283.303.232.5Young's Modulus (GPa) 285320315189Bend Strength (MPa) 675750850440Fracture Toughness K1c (MPa.m0.5) 6782.5Hardness (GPa) 1616167.2Thermal Expansion Coefficient (x 10-6/°C) 3.23.23.23.2Thermal Conductivity (W/m.K) 25303014Maximum Temperature (°C) for application 1150115011501100Dielectric Constant 9997.5Abrasive Wear resistance Parameter 111011101120360 Company Profile Based on quartz and ceramics, after more than 20 years development, Highborn Group has grown up to a modern enterprise in research, manufacture, processing and sales.
