Four paste compositions were manufactured using two powder mixtures (Ti/Si/C and Ti/TiC/Si/C) with different stoichiometry. The pastes were screen printed onto Al2O3 substrates and sintered at 1400 ℃ in argon varying the dwell time from 1 to 5 h. The printed pastes containing TiC and excess of Si exhibited the lowest surface roughness and after 5 h sintering comprised of Ti3SiC2 as the majority phase. The electrical conductivity of this sample was found to range from 4.63×104 to 2.57×105 S·m-1 in a temperature range of 25-400 ℃. {URL}: https://www.sciopen.com/article/10.1007/s40145-020-0427-0 {Language}: en
