A comparison between a new Ultra Fast Pressureless Sintering (UFPS) technology and Spark Plasma Sintering (SPS) for Barium AluminoSilicate metastable phase

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