Hydrogen peroxide, turned with 300-400/speed of part adds dodecylbenzene sodium sulfonate after stirring 10-15 minutes, continues stirring 15-
20 minutes, the sodium hydroxide with the 1mol/L of hydrogen peroxide equivalent is subsequently adding, continues stirring until precipitation completely, isolates precipitation
Thing, is put in baking oven with 80-90 DEG C of drying, finally crushes, and crosses 300 mesh sieves；
（4）By step（2）Step（3）The product for obtaining is put in mortar, is ground to material mix homogeneously, is subsequently poured into mould
In, 150-160 DEG C is heated to, mould is placed on electric tablet machine, the hot pressing 20-30 minutes under the pressure of 10MPa, wait to grind
Tool carries out the demoulding after being cooled to room temperature, finally polishes smooth the electrode material surface for obtaining with sand paper.
