A ceramic coping for dental restoration is provided to allow increasing intensity of the ceramic coping by generating stress difference and to secure minimal intensity or tenacity in spite of low temperature curing. A ceramic coping for dental restoration includes: at least one material selected from alumina(A1203) or zirconia(ZrO2), and an oxidized titanium(La2O3) and silica(SiO2), wherein the mix ratio of alumina(A1203) or zirconia(ZrO2), and the oxidized titanium and the silica is within a range of 1:1.2:2 ~ 1:2:3. The ceramic coping slurry comprises: 15 ~ 35 wt% of oxidized titanium; 10~25 wt% of silica dioxide(SiO2); 10~25 wt% of oxidized aluminum; 6~20 wt% of oxidized boron; 5~20 wt% of oxidized calcium; 0~10 wt% of zirconia; 0~10 wt% of oxidized tartar; 0~15 wt% of oxidized selenium; and 0~5 wt% of oxidized iron.
