The invention provides a ZrO2
ceramic surface electric conduction method. The ZrO2
ceramic surface electric conduction method comprises the steps: (1)
processing a plurality of grooves in the surface of a ZrO2
ceramic finished product; (2) ball-milling
glaze powder,
electrically conductive ceramic
powder and gloss oil to obtain electric conductive
slurry, wherein the
glaze powder comprises Al2O3 and SiO2 and further comprises at least one of Na2O, K2O, CaO, MgO, B2O3 and ZnO; (3) carrying out silk-
screen printing on the electric conductive
slurry at the grooves of the ZrO2 ceramic finished product, and
drying to obtain a
zirconium oxide blank; and (4) carrying out
sintering treatment on the
zirconium oxide blank at the
sintering temperature of 600 DEG C-1200 DEG C, and then carrying out
polishing treatment to prepare the
zirconium oxide ceramic with the
electrically conductive surface. According to the method, the surface
electrically conductive zirconium oxide ceramic is obtained at a relatively low
sintering temperature and is resistant to acid and alkali
corrosion; and moreover, good electrical
conductivity is achieved, a metalized layer is firmly combined with a
zirconia ceramic matrix, is not easy to crack and fall off, has a mirror surface effect and does not have macroscopic pores.
