Embodiment 1
[0021] A black ceramic pigment and a preparation method thereof. Its preparation method is:
[0022] 1) Mix the dust removal dust from electric furnace smelting stainless steel with chromium trioxide, nickel monoxide and manganese monoxide in a molar ratio of Fe:Cr:Ni:Mn=1:0.8:1.1:1.0 to obtain a mixed material;
[0023] 2) Place the mixed material in a microwave field, heat it for 15 minutes in an air atmosphere and a microwave power of 1.5kw, and keep it warm for 15 minutes when the temperature of the mixed material rises to 1100°C; then take the material out of the microwave field and cool it to room temperature in air , to obtain black ceramic pigments.
Embodiment 2
[0025] A black ceramic pigment and a preparation method thereof. Its preparation method is:
[0026] 1) Mix the dust removal dust from electric furnace smelting stainless steel with chromium trioxide, nickel monoxide and manganese monoxide in a molar ratio of Fe:Cr:Ni:Mn=1:1:0.5:1.2 to obtain a mixed material;
[0027] 2) Put the mixed material in the microwave field, heat it for 12 minutes under the condition of air atmosphere and microwave power of 2.4kw, when the temperature of the mixed material rises to 1075°C, keep it warm for 13 minutes; then take the material out of the microwave field, and air cool to room temperature , to obtain black ceramic pigments.
Embodiment 3
[0029] A black ceramic pigment and a preparation method thereof. Its preparation method is:
[0030] 1) Mix the dust removal dust from electric furnace smelting stainless steel with chromium trioxide, nickel monoxide and manganese monoxide in a molar ratio of Fe:Cr:Ni:Mn=1:1.3:0.7:0.7 to obtain a mixed material;
[0031] 2) Put the mixed material in the microwave field, heat it for 8 minutes under the condition of air atmosphere and microwave power of 3kw, when the temperature of the mixed material rises to 1150°C, keep it warm for 20 minutes; then take the material out of the microwave field, air cool to room temperature, A black ceramic pigment is obtained.
[0032] The black ceramic pigments prepared in Examples 1-3 and the commercially available cobalt-containing black ceramic pigment chromaticity CIE parameters are shown in Table 1
