Organic-inorganic hybrid ferroelectrics are piezoelectric materials with high piezoelectric voltage constants g₃₃, and materials with morphotropic phase boundary compositions are expected to offer further performance improvements. In this study, powders of the TMCM_1-xTMA_x-FeCl₄ ferroelectric system, which is composed of [Me₃NCH₂Cl]FeCl₄ and [Me₄N]FeCl₄ as end members, were synthesized using a mechanochemical method enabling rapid single-phase synthesis. Furthermore, high-dense pellets were fabricated by hot pressing the synthesized powders, and their dielectric properties were evaluated.
