A electric-conductive ceramic pigment is produced by (a) adding 4-5 wt.% methylethylketone to 10-12 wt.% polyurethane (30% solid solution), (b) mixing the mixt. with 5-6 wt.% BaTi2O3, 3-4 wt.% Al2O3, 0.5-1 wt.% SiN, and 4-5 wt.% zinc powder by the ball mill for 30-40 min, (c) mixing the mixt. with 70-73 wt.% conductive carbon, and (d) slow-stirring it. In the zinc powder, its purity is at least 99%, and particle size is pref 200-300 mesh.
