Silicon nitride bearing roller is a man-made composite product synthesized through several different chemical reaction methods. Due to the even performance in high temperature, Si3N4 cercmic 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.
