Blue ceramic pigment and preparation method thereof
The invention discloses a blue ceramic pigment and a preparation method thereof. The chemical composition of the blue ceramic pigment is Mg < 1 + x > Al < 2-2x > SixO4: yCo (x = 0.05-0.95, y = 0-0.9), raw materials of Mg, Al, Si and Co and a mineralizing agent are uniformly mixed, and the mixture is calcined at 1100-1500 DEG C for 1-10 hours to obtain a final product. According to the invention, Si is co-doped in Co-doped MgAl2O4 to regulate and control the crystal field environment around Co < 2 + > ions, so that high blue degree of the pigment is realized under the condition of low cobalt content. The blue coordinate of the prepared blue ceramic pigment is close to that of CoAl2O4 when the content of the cobalt component is 5wt%, and the blue ceramic pigment has the advantages of good color rendering property, low price and low toxicity, and can replace CoAl2O4 pigment to be used in different industries.
本发明公开了一种蓝色陶瓷颜料及其制备方法。蓝色陶瓷颜料的化学组成为Mg1+xAl2‑2xSixO4:yCo(x＝0.05‑0.95，y＝0‑0.9)，将Mg、Al、Si、Co原料及矿化剂混合均匀，在1100‑1500℃之间煅烧1‑10小时得到最终产品。本发明通过在Co掺杂MgAl2O4中共掺杂Si，以调控Co2+离子周围的晶体场环境，从而在低钴含量的条件下实现颜料高的蓝色度。本发明制备的蓝色陶瓷颜料在钴组分含量为5wt％时其蓝色坐标就接近于CoAl2O4，具有呈色性好、价格低、毒性低的优点，可以取代CoAl2O4颜料用于不同行业。
