High temperature characterization of LPS-SiC based materials with oxide additives

A high-strength SiCw/SiC–Si composite derived from pyrolyzed rice husks by liquid silicon infiltration

“…SiC ceramics matrix composites have been fabricated by various kinds of methods including conventional solid-state sintering [4], liquid-state sintering [5], hot pressing/hot isostatic pressing (HP/HIP) [6], liquid silicon infiltration (LSI) [7][8][9], polymer pyrolysis, and chemical vapor infiltration process (CVI) [1,10,11], etc. Among the above methods, LSI is an attractive method due to its relatively low fabrication temperature and short fabrication time [1,3,8].…”

Thermal shock properties of 2D-SiCf/SiC composites

“…Majority of R&D researches for the property evaluation of SiC f /SiC composites were also devoted to the establishment of baseline properties such as microstructure, bending strength, tensile strength, associated with the optimization of fabricating conditions [9][10][11][12]. Among the manufacturing processes of SiC f /SiC composites, liquid phase sintering (LPS) process can be recognized as an attractive method for providing the dense SiC matrix with a high crystalline [13,14]. In addition, the utilization of ultra-fine SiC powder with submicron or nano size for the fabrication of SiC f /SiC composites also was very effective * Corresponding author.…”

Microstructure and thermal shock property of liquid phase sintered Cf/SiC composites

“…The previous work showed that the infiltration technique of complex matrix slurry for the preparation of fiber preform was very effective for the densification of intra-fiber bundle region in SiC based composites [9]. Liquid phase sintering (LPS) process, which is associated with the transformation of sintering additives around SiC particles, is regarded as a promising method for the production of high crystalline SiC phases in the matrix [10,11]. The utilization of ultra-fine SiC particles can also promote the improvement of mechanical properties in C f /SiC composites through the strengthening of microstructure.…”
