本研究旨在利用流延成型技术将Al 2 O3纤维增强Al 2 O3基陶瓷材料（Al 2 O3-fiber/Al 2 O3 composite）制备成一种新型牙科陶瓷。Al 2 O3基陶瓷使用由60重量%的Al 2 O3粉末和40重量%的SiO2-B2 O3粉末组成的基质。采用流延成型技术，利用刮刀系统连续制备了Al 2 O3纤维/Al 2 O3复合材料预浸片（其中单轴Al 2 O3纤维与Al 2 O3基基体相互渗透）。然后在炉中在大气压下在1000 ℃的最高温度下烧结Al 2 O3-纤维/Al 2 O3复合片材的多层预成型件。结果表明，Al 2 O3纤维增强Al 2 O3复合材料的收缩率和弯曲性能均优于未增强Al 2 O3材料，从而证明了纤维增强的积极作用。本研究成功地利用流延成型技术研制出一种新型牙科陶瓷材料。
The purpose of this study was to use a tape casting technique to develop an Al2O3 fiber-reinforced Al2O3-based ceramic material (Al2O3-fiber/Al2O3 composite) into a new type of dental ceramic. The Al2O3-based ceramic used a matrix consisting of 60 wt% Al2O3 powder and 40 wt% SiO2-B2O3 powder. The prepreg sheets of Al2O3-fiber/Al2O3 composite (in which uniaxially aligned Al2O3 fibers were infiltrated with the Al2O3-based matrix) were fabricated continuously using tape casting technique with a doctor blade system. Multilayer preforms of Al2O3-fiber/Al2O3 composite sheets were then sintered at a maximum temperature of 1000 degrees C under an atmospheric pressure in a furnace. The results showed that the shrinkage and bending properties of Al2O3-fiber/Al2O3 composite exceeded those of unreinforced Al2O3--hence demonstrating the positive effects of fiber reinforcement. In conclusion, the tape casting technique has been utilized to successfully develop a new type of dental ceramic material.
