Abstract: Two processes to sinter monolithic hexagonal Barium AluminoSilicate (BAS) are compared in this study: Spark Plasma Sintering (SPS) and a new Ultra-Fast Pressureless Sintering (UFPS) technology developed by Galtenco Solutions®. For both, hexagonal BAS was sintered in its thermal stability range (between 1590 °C and 1760 °C). Results demonstrate that it is only possible to manufacture small parts (15 mm diameter/ 5 mm height) of hexagonal BAS with the SPS process. For larger or more complex shapes, a thermal gradient appears in the sample, leading to the partial melting of some of its body. On the other hand, the new UFPS technology enables the successful processing of large parts of hexagonal BAS with similar efficiency to SPS for small parts. This technology offers a better thermal control of the sintering and eliminates the thermal gradient issue that can be found in the SPS technique. [ABSTRACT FROM AUTHOR]
