51. Flash Spark Plasma Sintering ( FSPS) of Pure ZrB2.

Abstract

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. [ABSTRACT FROM AUTHOR]

53. Spark plasma sintering in a flash.

Abstract

The article reports on the development of a novel flash spark plasma sintering process for rapid heating and consolidation of materials as compared to electric-current-assisted sintering. Topics include the advantages of flash sintering such as densifying materials that are insulators even at room temperature, the use of flash sintering to materials outside of conductive ceramics, and the technique's potential for producing less expensive and more sustainable rare-earth-free permanent magnets.
