Method for preparing dental zirconia ceramic through low-temperature sintering
The invention relates to the technical field of composite non-metallic materials, in particular to a method for preparing dental zirconia ceramics through low-temperature sintering, which comprises the following steps: firstly, weighing 3Y zirconia ceramic granulation powder and nano silicon dioxide powder; the preparation method comprises the following steps: mixing nano silicon dioxide powder with 3Y zirconia ceramic granulation powder to obtain powder A; putting the powder A into a bag, flatly laying the bag on a vortex oscillator, and oscillating to obtain powder B; performing dry pressing on the powder B to obtain a biscuit C; performing heat treatment on the biscuit C to obtain a pre-sintered body D; and heating the pre-sintered body D to 1400 DEG C, preserving heat for 1-4 hours, and sintering to obtain the dental zirconia ceramic. According to the method, the sintering temperature is reduced to 1400 DEG C, so that the preparation time and cost of the zirconia ceramic dental crown can be shortened, the energy consumption is reduced, the requirement on a zirconia sintering furnace is also reduced, and a zirconia ceramic crystal structure is not changed.
本发明涉及复合非金属材料技术领域，具体涉及一种低温烧结制备齿科氧化锆陶瓷的方法，包括以下步骤：先称取3Y氧化锆陶瓷造粒粉和纳米二氧化硅粉体；将纳米二氧化硅粉体与3Y氧化锆陶瓷造粒粉混合，得到粉体A；将粉体A装入袋子中，平铺放置于旋涡振荡器上震荡，得到粉体B；将粉体B干压成型，得到素坯C；将素坯C进行热处理，得到预烧结体D；对预烧结体D升温至1400℃后，保温1‑4小时烧结，即制得齿科氧化锆陶瓷。本发明将烧结温度降低至1400℃，从而能够缩短氧化锆陶瓷牙冠的制备时间和成本，降低能耗，也降低了对氧化锆烧结炉的要求，且不改变氧化锆陶瓷晶体结构。
