采用脉冲电炉（FSPS）对纯ZrB2粉末进行了闪蒸烧结。在16 MPa的压力下，试样在35 s内致密化达95.0%。与传统的SPS （CSPS）相比，新开发的FSPS技术可以节省前所未有的能源和时间，分别约为95%和98%。比较了CSPS和FSPS制备的ZrB2单块体的显微组织、致密化行为和晶粒生长。所开发的方法可以广泛应用于高导电性陶瓷，如耐火硼化物和碳化物。
Pure ZrB2 powder was Flash sintered in an SPS furnace (FSPS). The samples were densified up to 95.0% in 35 s under an applied pressure of 16 MPa. Compared to Conventional SPS (CSPS), the newly developed FSPS technique resulted in an unprecedented energy and time savings of about 95% and 98% respectively. ZrB2 monoliths obtained by CSPS and FSPS were compared with respect to microstructures, densification behavior, and grain growth. The developed methodology might find application to a wide range of highly conductive ceramics as such refractory borides and carbides.
