Embodiment 1
[0031] Ceramic pigment composition, black glass ceramic pigment, glass ceramic and preparation method thereof, comprising the following steps: according to mass percentage, respectively weighing 6% Fe 2 o 3 , 7%Cr 2 o 3 , 6% MnCO 3 , 5% CuO, 6% NiO, 3% boric acid and 67% ternary mixture (the ternary mixture includes 40% kaolin, 40% CaCO 3 and 20% BaCO 3 ). After the raw materials are ground evenly, a small amount of water is added to make a mud base. After drying, it is calcined at 1300°C for 2 hours, crushed and ground, and passed through a 120-mesh sieve to obtain a black glass ceramic pigment. Mix 15% pigment, 8% fluoromica and 77% glass powder evenly, add 6% polyvinyl alcohol aqueous solution to make the material bond, put it into a mold, and press it with a pressure of 7.5MPa. ℃ for 4 hours and then cooled with the furnace to obtain black glass ceramics added with fluoromica.
[0032] As shown in Figure 1, it can be seen that after sintering with the addition of bl...
Embodiment 2
[0035] Ceramic pigment composition, black glass ceramic pigment, glass ceramic and preparation method thereof, comprising the following steps: according to mass percentage, respectively weighing 12% Fe 2 o 3 , 8%Cr 2 o 3 , 7% MnCO 3 , 3% CuO, 5% boric acid and 65% ternary mixture (the ternary mixture includes 35% kaolin, 50% CaCO 3 and 15% BaCO 3 ). After the raw materials are ground evenly, a small amount of water is added to make a mud base. After drying, it is calcined at 1100°C for 4 hours, crushed and ground, and passed through a 140-mesh sieve to obtain a black glass ceramic pigment. Mix 20% pigment, 5% anorthite and 75% glass powder evenly, add 8% polyvinyl alcohol aqueous solution to bond the material, put it into a mold, and press it with a pressure of 12MPa. After one hour of heat preservation, it is cooled with the furnace to obtain black glass ceramics with anorthite added.

Embodiment 3
[0039] Ceramic pigment composition, black glass ceramic pigment, glass ceramic and preparation method thereof, comprising the following steps: according to mass percentage, respectively weighing 9% Fe 2 o 3 , 6%Cr 2 o 3 , 5% MnCO 3 , 4% CuO, 3% NiO, 4% boric acid and 69% ternary mixture (the ternary mixture includes 45% kaolin, 45% CaCO 3 and 10% BaCO 3 ). After the raw materials are ground evenly, a small amount of water is added to make a mud base, and after drying, it is calcined at 1200°C for 3 hours, crushed and ground, and passed through a 100-mesh sieve to obtain a black glass ceramic pigment. Mix 10% pigment, 10% enstatite and 80% glass powder evenly, add 7% polyvinyl alcohol aqueous solution to make the material bond, put it into a mold, and press it with a pressure of 10MPa. After heat preservation for 3 hours, it was cooled with the furnace to obtain black glass ceramics with enstatite added.
