PURPOSE: A manufacturing method of perovskite-based brown pigment is provided to provide perovskite-based brown pigment capable of obtaining natural brown color, and excellent high-temperature stability. CONSTITUTION: A manufacturing method of perovskite-based brown pigment comprises: a step of calcium carbonate, titanium oxide, and chrome oxide; and a step of calcining the mixture. The mixing molar ratio of the calcium carbonate, the titanium oxide, and the chromium oxide is 1 : 0.96 - 0.195 : 0.01 - 0.05. The calcining step is conducted at 1200-1400°C for 1-5 hours. The perovskite-based brown pigment is CaTiO3 in which solid chrome is solved. |
