“…SiC fiber reinforced SiC matrix composites (SiC f /SiC) have been extensively studied as a promising material for the blanket first wall and coolant channel [1,2]. A major research for high performance SiC f /SiC composites has been concentrated on the production of high purity SiC matrix and its densification into the fiber bundle [3][4][5]. The liquid phase sintering (LPS) process has an advantage for providing a high density of SiC materials, owing to the transformation of additive materials into some eutectics between SiC particles.…”
