Figure 5.27 (a) Bulk density, (b) relative density and (c) average grain size vs sintering temperature for monolithic SiC prepared by SPS of Si, C, and B powder mixtures.

Major drawbacks of PDCs are large weight loss and shrinkage of ceramics during pyrolysis. During the nanocomposite fabrication, CNTs are dispersed in liquid-phase polymer under sonication, followed by pyrolysis of dried powder mixture. Yamamoto et al. [116] prepared SiC/SWNTnanocomposites by pyrolysis PCS precursor at 1400 C in vacuum. SiC nanoparticles of 14.6–22.4 nm were deposited onto SWNTs. An et al. [56] and Katsuda et al. [117] fabricated Si-C-N/ MWNT nanocomposites by using PSZ precursor. PSZ possesses amorphous network which transforms to amorphous silicon carbonitride ceramics upon pyrolysis at 1000–1100 C [118].
160j 5 Carbon Nanotube–Ceramic Nanocomposites Figure 5.28 (a) Bulk density; (b) relative density; (c) average grain size vs carbon nanofiber content, for SiC/VGCF nanocomposites prepared by SPS of Si, C, B and VGCF powder mixtures at 1800 C. Reproduced with permission from [114]. Copyright Ó (2007) Elsevier. 5.6 Nitride-Based Nanocomposites 5.6.1 Silicon Nitride Matrix It is recognized that silicon nitride is difficult to sinter and consolidate into a dense material using conventional sintering processes. The incorporation of CNTs into silicon nitride would further impair its sinterability. Balazsi et al. fabricated the Si3N4/ 1% MWNT nanocomposite using hot isostatic pressing and SPS [43, 119, 120]. For the hipping process, ball-milled composite powder mixtures were sintered at 1700 C under a pressure of 20 MPa for 3 h, and under 2 MPa for 1 h, respectively. In the case of SPS, ball-milled composite powder mixtures were consolidated at 1500 C under 100 MPa for 3 min, and at 1650 C under 50 MPa for 3 min, respectively.
