The present invention, CaO 20.0~40.0 mol%, Al 2 O 3 3.0~15.0 mol%, P 2 O 5 45.0~65.0% by mole, NiO 0.001~2.0 mol%, Li 2 O 0.1~7.0% by mole, TiO 2 0.01 To 3.5 mol% of ZrO 2 and 0.001 to 3.5 mol% of ZrO 2, and a method for producing the same. According to the ceramic ingot for artificial teeth of the present invention, since the thermal conductivity is similar to that of the natural teeth, the tooth whitening phenomenon can be suppressed, the translucency and color similar to that of the natural teeth are exhibited, Is very similar to natural teeth, so that abrasion of natural teeth can be suppressed. |
