Abstract: The synthesis and characterization of ceramic composites based on the ZrO₂(MgO)–CaSiO₃ system were investigated, focusing on their phase composition, crystal structure, and lattice parameters. The results demonstrate that sintering temperature and increasing wollastonite content significantly influence the structural formation, complex phase composition, and phase transformations within the ZrO₂(MgO)–CaSiO₃ system. The phase composition of ZrO₂ and CaSiO₃ was analyzed across sintering temperatures ranging from 1000°C to 1650°C and wollastonite contents of 1–25 vol.%. The samples exhibited five distinct phases: tetragonal, cubic, and monoclinic phases of zirconium dioxide, along with monoclinic and triclinic phases of wollastonite. Notably, the interplanar spacings of the m-ZrO₂ and m-CaSiO₃ phases changed markedly within the 1200–1300°C sintering range. This is attributed to intensive interfacial interactions between zirconium dioxide and wollastonite, resulting in alterations to the structural state of the composites, phase composition, phase distribution, and lattice parameters of the zirconium dioxide and wollastonite phases.
