The preparation of ZrO2-Al2O3 composite ceramic by SLA-3D printing and sintering processing

The objectives of this study were to investigate the mechanical properties of a ZrO2- Al2O3 composite ceramic. The mechanical strenght, wear behaviour and phase composition of the ceramic composite were analysed. The tested material showed a significantly higher bending strength compared to Al2O3- and ZrO2-Ceramic. According to the results of ring-on-disc, the wear rates were comparable to the Al2O3-Ceramic.

First Time

Although the excellent properties of borides have attracted the attention of the industry, their limited preparation process and difficult-to-remove impurities have prevented them from exerting their full effectiveness. However, it is very difficult to separate AlB12 and Al2O3 prepared by self-propagating high temperature synthesis. This study is the first time to separate the two by electrolysis process and observe their electrolytic behavior. The results show that Al2O3 is converted into micron-sized aluminum during the electrolysis process, while AlB12 still exists intact. This result provides a novel idea for the future purification of borides containing Al2O3 impurities

Abstract The effect of (1-x)(Pb0.97La0.02)(Zr0.675Sn0.285Ti0.04)O3-xAl2O3, with x=0~0.04, 0.08, 0.10 composite ceramic samples was studied. In this experiment, the PLZST powder was pre-fired to obtain the perovskite structure, and then combined with α-Al2O3 to increase the BDS of the ceramic. The test results show that the composite thick film samples are all perovskite orthorhombic phases, and Al2O3 is mainly filled in the grain gaps with a flaky structure. A proper content of composite Al2O3 can increase the density of ceramics. With x=0.02, the maximum value of BDS is 25.27 kV/mm, which is 60% higher than pure PLZST material, and the releasable energy storage density also reaches a maximum of 2.95 J/cm³. After the composite amount exceeds 0.03, the saturation polarization intensity decreases significantly. The energy storage efficiency of each sample is generally not high, all of which are less than 65%.
