1. a method of preparing the carbon metal compound composite material that refining electrolytic bath uses, the main ingredient of described carbon metal compound composite material is SiC, C, Si 3n 4and Si, wherein SiC accounts for the 50-95% of gross weight, and C accounts for 1-33%, the Si of gross weight 3n 4account for the 1-35% of gross weight, Si accounts for the 0.1-30% of gross weight, and its key step is:

  • A) by SiC, C, Si 3n 4with Si in proportion weigh batching, aftershaping mixes;

    B) matrix material of steps A gained is carried out to nitrogenize and burn till, temperature is 1380-1560 ℃

    , and the time is 100-200 hour;

    C) matrix material of step B gained floods 8-60 hour in bituminizing liquid;

    D) infused composite of step C gained is at nitrogen or 200-1500 ℃

    of roasting in burying carbon, and the time is 48-200 hour.
