Synthesis of Ti2SnC from Ti/Sn/TiC powder mixtures by pressureless sintering technique

Ti/Sn/TiC powder mixtures were used to synthesise Ti2SnC powder by pressureless sintering in the temperature range of 950-1250 C in a vacuum. Ti2SnC began to form at 950 C, but its content increased with increasing temperature. High purity Ti2SnC was obtained by sintering the mixtures with deficient...

Description
Summary:Ti/Sn/TiC powder mixtures were used to synthesise Ti2SnC powder by pressureless sintering in the temperature range of 950-1250 C in a vacuum. Ti2SnC began to form at 950 C, but its content increased with increasing temperature. High purity Ti2SnC was obtained by sintering the mixtures with deficient Sn and TiC at 1200 C for 15 min. A reaction mechanism was proposed to explain the formation of Ti2SnC. The Ti2SnC powder was characterised by SEM and XRD. Using the above mixtures and process, Ti2SnC ceramic powder can be obtained on a larger scale. 9 refs.
