Barium silicon is also called barium silicon inoculant which is a long-term graphitization. Compared with graphitization ability of ferro silicon, it can improve the different thickness of the section structure and hardness uniformity as well as increase the number of eutectic group and recession speed is slow. Increasing the same quantity, barium silicon inoculation can improve tensile strength higher 20-30N/mm2 than ferro silicon.
