The possibility to fabricate highly dense (95.3–95.8% of theoretical density) composite ceramics CeO₂ – x α-SiC (x = 10, 20 vol %) as a promising mineral-like material for the inert fuel matrices (IFM) by Spark Plasma Sintering (SPS) has been explored. The kinetics of SPS of the CeO₂ – SiC composites in the heating-up conditions was found to have a multi-stage character. The introduction of the α-SiC particles resulted in a shift of the characteristic sintering temperatures towards higher values, allows forming the highly dense fine-grained structure, and leads to increasing of the thermal conductivity of the cerium dioxide – based ceramics.

的可能性，制造高密度（理论密度的95.3-95.8％）复合陶瓷的CeO ₂ - X α-SiC单晶（X  = 10，20体积％），其为希望的矿物类材料为惰性的燃料矩阵（IFM）由火花已经探索了等离子体烧结（SPS）。发现CeO ₂ -SiC复合材料在加热条件下的SPS动力学具有多阶段特征。α-SiC颗粒的引入导致典型的烧结温度向更高的值转变，允许形成高密度的细晶粒结构，并导致二氧化铈基陶瓷的导热系数增加。
