• Phase transitions in Bi4-xSmxTi3O12 single crystals in the Sm concentration range of $x\leq 0.61$ were studied. The phase transition near 670 °C was found to remain almost unchanged in the concentration range of $0\leq x\leq 0.61$. Below the transition temperature of 670 °C, dielectric anomaly showing phase transitions was found in BSmT-$x$, depending on the concentration $x$. It was confirmed that the triggered transition from the tetragonal phase to the monoclinic phase, observed in Bi4Ti3O12, splits into two phase transitions by adding Sm cations, i.e., from the tetragonal phase to the orthorhombic phase and further to the monoclinic phase. The temperature-concentration phase diagram of the BSmT-$x$ system was clarified.
