C_0.3N_0.7Ti-SiC Toughed Silicon Nitride Hybrids with Non-Oxide Additives Ti₃SiC₂

“…3(e) suggests dominant phase of Si3N4 and SiC, which is associated with reaction described by Eq. (10). Additional O element may be originated from surface of raw α-Si3N4 powders.…”

“…[1][2][3][4][5][6][7][8][9] . As important multifunctional materials, Si3N4 ceramics have found wide range of successful application towards gas turbine engine components [10][11][12][13] , cutting tools [10,14] , radomes [2] , and even integrated circuit [15,16] , optical devices [17,18] , etc. However, due to the high degree of covalent bonding, Si3N4-based ceramics are very difficult to densify through the solid-state sintering process.…”

“…However, due to the high degree of covalent bonding, Si3N4-based ceramics are very difficult to densify through the solid-state sintering process. Therefore, effective approaches to ensure rapid consolidation and high mechanical performance of Si3N4-based ceramics are actively being explored, including gas pressure sintering (GPS) [10] , hot-pressing sintering (HPS) [19][20][21][22][23][24][25] , hot isostatic pressing sintering (HIP) [26] , spark plasma sintering (SPS) [25,27,28] , and microwave sintering [1,29] , etc. However, considering the requirement of high gas pressures for gas pressure sintering and extra current devices for SPS with a significantly higher furnace costs, HP sintering allows the dense and complex-shaped parts with medium cost.…”
