Ca2TiSiO6
Ca2TiSiO6 is a semiconducting perovskite titanate containing calcium, titanium, and silicon that exists in a metastable state.
About Ca2TiSiO6
Ca2TiSiO6 is a semiconducting member of the perovskite titanate family, characterized by its complex arrangement of calcium, titanium, silicon, and oxygen atoms. Its electronic nature makes it a subject of interest for researchers investigating potential functional materials within the broader titanate system.
While this compound exhibits structural diversity with multiple reported configurations, it is categorized as thermodynamically unstable relative to its constituent phases. This positioning highlights the synthetic challenges often associated with complex silicate-titanate perovskite derivatives.
Key Properties

How It Compares
Within the perovskite titanates class.
Within the diverse family of perovskite titanates, Ca2TiSiO6 serves as a complex structural relative to more stable, widely utilized members like CaTiO3 and BaTiO3. Unlike these archetypal ferroelectric and dielectric materials, Ca2TiSiO6 incorporates silicon into the lattice, placing it in a distinct subgroup alongside compounds like CaTiSiO5, where the interplay between the silicate and titanate frameworks dictates its unique, albeit metastable, structural profile.
