Black ceramic pigment, black zirconia ceramic powder, black zirconia ceramic and preparation method thereof
The invention relates to the field of ceramics, and particularly discloses a black ceramic pigment, black zirconia ceramic powder, black zirconia ceramic and a preparation method thereof. The black ceramic pigment comprises a composite doped material Ti<1-x-y>(AB)O , wherein A is at least one selected from Mg, Ca, Sr, Zn, La, Sm, Bi and In, B is at least one selected from Ta, Sn, Nb and Fe, x is more than 0.001 and less than 0.15, and y is more than 0.001 and less than 0.2. The black ceramic pigment further comprises a color former, the color former is at least one metal oxide selected from chromium-containing oxide, tungsten oxide and molybdenum oxide, and the molar ratio of Ti to metal elements in the color former is (20-99): 1. The black zirconia ceramic powder comprises 75-97 parts of yttria-stabilized zirconia and 3-25 parts of the black ceramic pigment. The black zirconia ceramic with pure color, uniform color and good color controllability can be obtained.
本申请涉及陶瓷领域，具体公开了一种黑色陶瓷色料、黑色氧化锆陶瓷粉体、黑色氧化锆陶瓷及其制备方法。黑色陶瓷色料包含复合掺杂型材料Ti1‑x‑y（AxBy）Oz，A选自Mg、Ca、Sr、Zn、La、Sm、Bi、In中至少一种，B选自Ta、Sn、Nb、Fe中至少一种，0.001＜x＜0.15，0.001＜y＜0.2。黑色陶瓷色料还可包含发色剂，发色剂选自含铬氧化物、氧化钨、氧化钼中至少一种金属氧化物，Ti与发色剂中金属元素的摩尔比为（20~99）:1。黑色氧化锆陶瓷粉体包括钇稳定氧化锆75~97份、黑色陶瓷色料3~25份。本申请能得到颜色纯正、颜色均匀、颜色可控性佳的黑色氧化锆陶瓷。
