Embodiment 1

[0011] Embodiment 1: Calcium carbonate, tin slag, silicon dioxide are pressed by CaO:SnO 2 :SiO2 2 = 1:1:1 molar ratio mixing, then add the colorant Cr of 2% of the total mass fraction of the mixture 2 o 3 and 10% mineralizer borax were put into a muffle furnace and kept at 1200° C. for 30 minutes, cooled naturally, washed with water, dried, and ground to 400 mesh to obtain chrome-tin red material.

[0012] In the base glaze:

[0013] 0.276 K 2 O 0.066 Na 2 O 0.658 CaO 0.003 Fe 2 ...

Embodiment 2

[0015] Embodiment 2: Calcium carbonate, tin slag, silicon dioxide are pressed by CaO:SnO 2 :SiO2 2 = 1.5: 0.6: 1 molar ratio mixing, then add the coloring agent K of 4% of the total mass fraction of the mixture 2 Cr 2 o 7 and 15% mineralizer boric acid were put into a muffle furnace and kept at 1100° C. for 60 minutes, cooled naturally, washed with water, dried, and ground to 400 mesh to obtain chrome-tin red material.

Description

technical field [0001] The invention and the preparation method of the red pigment specifically relate to a preparation method of the chrome-tin red pigment. technical background: [0002] Chromium tin red material is a kind of purple red ceramic color material with a long history, and its color carrier has gray tin ore (CaSnO 3 ) type and tin sphene (CaSnSiO 5 ) type in two forms. Tin red material is rich in color, and can be in various shades such as deep red, rose red, purple red, lilac purple and so on. Its elegant color is loved by people, and it is one of the widely used pigments for high-end architectural sanitary ceramics. [0003] Tin dioxide is an indispensable and important raw material for the preparation of chromium-tin red material, and its dosage increases with the increase of the demand for chromium-tin red material. In recent years, with the rapid development of the global industry and the rising price of chemical raw material tin dioxide, the preparatio...
