Colored ceramic and preparation method thereof
The invention relates to the technical field of photocuring forming, in particular to colored ceramic and a preparation method thereof. The preparation method of the colored ceramic comprises the steps that ceramic slurry containing a white and/or light-color coloring agent is subjected to photocuring forming, a ceramic blank is obtained, then the ceramic blank is subjected to degreasing and sintering in sequence, and the colored ceramic is obtained; compared with color ceramic slurry containing CoO, Cr2O3, Fe2O3 and other rare earth metal or transition metal oxides for photocuring forming, the ceramic slurry containing the white and/or light coloring agent is low in absorbance and high in energy when used for photocuring resin, the situation that the curing depth becomes shallow in the ceramic slurry curing forming process is slowed down, compared with a three-dimensional ceramic body shape preset by a computer, the ceramic blank deformation caused by the fact that the curing depth becomes shallow is improved, and the efficiency and precision of photocuring forming of the ceramic blank are improved. According to the colored ceramic and the preparation method thereof provided by the invention, the technical problems of low efficiency and precision of photocuring formed colored ceramic can be solved.
本发明涉及光固化成型技术领域，具体涉及一种彩色陶瓷及其制备方法。本申请提供的彩色陶瓷的制备方法包括将含有白色和/或浅色着色剂的陶瓷浆料光固化成型，得到陶瓷胚体，然后将陶瓷胚体依次进行脱脂、烧结，得到彩色陶瓷；其中，与含有CoO、Cr2O3、Fe2O3等稀土金属或过渡金属氧化物的彩色陶瓷浆料光固化成型相比，含有白色和/或浅色着色剂的陶瓷浆料吸光度低，用以光固化树脂的能量高，减缓了陶瓷浆料固化成型过程中固化深度变浅，改善了与电脑预设三维陶瓷胚体形状相比，固化深度变浅导致的陶瓷胚体变形，提高了光固化成型陶瓷胚体的效率和精度。本申请提供的一种彩色陶瓷及其制备方法，可以解决光固化成型彩色陶瓷效率和精度低的技术问题。
