Examples
Embodiment 1
[0023] Add 50g of quartz sand, 145.5g of cobalt nitrate and 375.1g of aluminum nitrate to 500mL of water, stir at high speed for 30min, then slowly add NaOH until the pH of the system is 10; In a type furnace, it was crystallized at 1100°C for 1 hour to obtain a blue-green hybrid pigment, sample number S1.
Embodiment 2
[0025] Add 50g of quartz sand, 116.4g of cobalt nitrate, 375.1g of aluminum nitrate and 10.1g of potassium nitrate into 500mL of water, stir at high speed for 30min, then slowly add NaOH until the pH of the system is 10; react for 1h, and the obtained solid product is centrifuged and washed After that, it was directly placed in a tube furnace and crystallized at 1000°C for 1 h to obtain a blue hybrid pigment, sample number S2.
Embodiment 3
[0027] Add 100g albite, 142.8g cobalt chloride, 450.1g aluminum nitrate and 22.2g calcium chloride to 1000mL water, stir at high speed for 30min, then slowly add NaOH until the pH of the system is 11; react for 1h, the obtained solid product is centrifuged, After washing, it was directly placed in a tube furnace and crystallized at 1200 °C for 1.5 h to obtain a bright blue hybrid pigment, the sample number of which was S3.
