Silicon Nitride Tube is a covalent bond compound with high strength, low density, and high temperature resistance. Nextgen Advanced Materials supplies the Silicon Nitride Tube with high quality and fast delivery. Meanwhile, the customization is available.
Nextgen Advanced Materials INC is manufacturer & supplier who mainly produces Silicon Nitride Tube with many years of experience. Hope to build business relationship with you. Silicon nitride tube is made of a high-melting-point ceramic material that is extremely hard and relatively chemically inert. Si3N4 is a man-made compound synthesized through several different chemical reaction methods. Due to the even performance in high temperature, Si3N4 is a commonly used ceramic material in the metallurgical industry. It has excellent thermal shock resistance due to the microstructure. The creep and oxidation resistance of Si3N4 is also superior, its low thermal conductivity and high wear resistance also make it an outstanding material that can withstand conditions of most industrial applications.
