        several special silicon carbide products

        The code names of several special silicon carbide products;
        recrystallized silicon carbide-RSIC
        reaction sintered silicon carbide-SISIC
        silicon nitride combined with silicon carbide-NSIC
        oxide combined with silicon carbide-OSIC
         
        description:
          1. "Recrystallized silicon carbide" The title of "recrystallized silicon carbide" in the silicon carbide rod industry before.
          2. "Reaction sintered silicon carbide" is also expressed by ReSIC. Its meaning is different from SISIC. The difference lies in the difference in process, but the final composition of the product is still similar, so SISIC is used in the standard.
          3. The code name of "Oxide Bonded Silicon Carbide" was originally "OC". At the Wuyishan Standards Review Meeting in December 2011, the proposal of Zibo Qunqiang Company was adopted and the code name was revised from "OC" to "OSIC".
