چکیده انگلیسی
SiC-Zr2CN composites were fabricated from β-SiC and ZrN powders with 2 vol% equimolar Y2O3-Sc2O3 additives via conventional hot pressing at 2000 °C for 3 h in a nitrogen atmosphere. The electrical and thermal properties of the SiC-Zr2CN composites were investigated as a function of initial ZrN content. Relative densities above 98% were obtained for all samples. The electrical conductivity of Zr2CN composites increased continuously from 3.8 Ã 103 (Ωm)â1 to 2.3 Ã 105 (Ωm)â1 with increasing ZrN content from 0 to 35 vol%. In contrast, the thermal conductivity of the composites decreased from 200 W/mK to 81 W/mK with increasing ZrN content from 0 to 35 vol%. Typical electrical and thermal conductivity values of the SiC-Zr2CN composites fabricated from a SiC-10 vol% ZrN mixture were 2.6 Ã 104 (Ωm)â1 and 168 W/m K, respectively.
