Preparation method of high-strength and high-compactness ceramic material
The invention relates to a preparation method of a high-strength and high-compactness ceramic material, which comprises the following steps: (1) ball milling: putting zirconium oxide powder, nano titanium nitride powder, titanium powder and zinc oxide powder into a ball mill for ball milling for 10-12 hours at the ball milling rotating speed of 300-350r/min, and taking out and drying after ball milling to obtain mixed powder; (2) granulation: mixing the mixed powder and an organic binder on a double-roller mixing mill for 30-45 minutes at the mixing temperature of 130-140 DEG C, and then cooling and crushing to 1-2 mm to obtain a mixture for 3D printing; (3) 3D printing; and (4) sintering. According to the preparation method of the high-strength and high-compactness ceramic material, the nano titanium nitride and the titanium conductive phase are added into the zirconium oxide matrix and matched with the sintering aid ZnO, so that the conductivity of the zirconium oxide ceramic is improved, the densification process is completed and the growth of crystal grains is inhibited by adopting a method of combining 3D printing and two-step sintering, and the high-strength and high-compactness ceramic material is obtained. The strength and the compactness are improved.
一种高强高致密性的陶瓷材料的制备方法，包括如下步骤：（1）球墨：将氧化锆粉体、纳米氮化钛粉体、钛粉体、氧化锌粉体放入球磨机进行球磨，球磨时间为10‑12h，球磨转速300‑350r/min，球磨完成后，取出烘干，得到混合粉体；（2）造粒：将上述混合粉体与有机粘结剂在双辊混炼机上混合30‑45min,混合温度为130‑140℃,然后冷却破碎至1‑2mm,得到3D打印用混合料；（3）3D打印；（4）烧结。本发明所述的高强高致密性的陶瓷材料的制备方法，通过向氧化锆基体添加纳米氮化钛、钛导电相，配合烧结助剂ZnO，提高了氧化锆陶瓷的导电性能，通过采用3D打印、两步烧结相结合的方法，完成致密化过程的同时又抑制晶粒的长大，提高强度、致密性。
