以xwt.% ZnO为烧结助剂（其中x=0、0.5、1.0、2.0和3.0），通过微波烧结工艺成功制备了致密NaZr2(PO4)3(NZP)陶瓷。系统研究了ZnO添加剂对所制备NZP陶瓷晶体结构、显微结构和烧结行为的影响。通过微波烧结技术，可以在900-1200°C的宽温度范围内保持2小时获得单一NZP相。 ZnO烧结助剂的添加不会明显改变NZP的晶体结构。重要的是，ZnO添加剂显着促进了致密化，添加1.0wt% ZnO的样品在1100℃烧结后的最大相对密度为96.5%，明显高于纯NZP样品。此外，上述样品的维氏硬度可以达到接近800MPa，大约是不含ZnO添加剂的纯NZP陶瓷的四倍。研究表明，微波烧结与适当添加ZnO烧结助剂相结合，将为快速制备致密NZP陶瓷提供一种便捷有效的方法。
The dense NaZr2(PO4)3(NZP) ceramics were successfully prepared by a microwave sintering process withxwt.% ZnO as a sintering aid (wherex= 0, 0.5, 1.0, 2.0 and 3.0). The effects of ZnO additive on the crystal structure, microstructure and sintering behavior of as-prepared NZP ceramics were systematically investigated. The single NZP phase can be achieved in the wide temperature range of 900–1200 °C holding for 2 h by microwave-sintering technology. The addition of ZnO sintering aid would not noticeably change the crystal structure of NZP. Importantly, ZnO additive significantly promoted the densification and 1.0 wt% ZnO-added sample possessed the maximum relative density of 96.5% after sintering at 1100 °C, considerably higher than that of pure NZP sample. Besides, the Vickers hardness of the above sample could attain near 800 MPa, which is about four times as hard as the pure NZP ceramics without ZnO additive. It was suggested that the combination of microwave sintering with appropriate addition of ZnO sintering aid would provide a convenient and efficient method for rapid fabrication of dense NZP ceramics.
