In this work, we explore factors affecting the accuracy of the master sintering curve (MSC) approach for analyzing the complete sintering profile of ceramic powders. We show that the instantaneous anisotropic shrinkage must

Texture-engineered ceramics enable access to a vast array of novel texture-property relations leading to property values ranging between those of single crystals and isotropic bulk ceramics. Recently developed templated grain growth and magnetic alig

Pb2+-doped (Sr1− xPbx)3Ti2O7 (SPT) ceramics were fabricated by a solid state reaction. The stability and lattice structure of Sr3Ti2O7 and Sr4Ti3O10 Ruddlesden–Popper (RP) phases were studied as a function of Pb2+ content and sintering atmosphere

A novel combination of low-field magnetic alignment (MA) and templated grain growth (TGG) was used to fabricate highly textured diamagnetic 0.72Pb(Mg1/3Nb2/3)O3–0.28PbTiO3 (0.72PMN–0.28PT) ceramics. Samples were produced by nonaqueous slip castin

Nucleation, texture development, and phase equilibria were observed during templated grain growth (TGG) of (Na0.5K0.5)0.98Li0.02NbO3 (NKLN) via in situ X-ray diffraction (XRD). Initially, NaNbO3 templates and NKLN matrix powder exist as distinct phas

In reactive templated grain growth (RTGG), oriented template crystals are used to seed both phase formation and crystallographic orientation in textured ceramics. This mechanism differs substantially from templated grain growth (TGG), in which textur

In this work, we report the electromechanical properties of 〈00l〉C-textured (K0.5Na0.5)0.98Li0.02NbO3 (KNLN) and (K0.5Na0.5)(Nb0.85Ta0.15)O3 (KNNT) ceramics produced by templated grain growth. Both materials show high texture quality (F00l=98% an

Perovskite microplatelets of the composition 0.4(Na1/2Bi1/2) TiO3–0.6PbTiO3 (0.4NBT–0.6PT) were synthesized by topochemical conversion of the Aurivillius phase PbBi4Ti4O15 in a NaCl/Bi2O3/PbO flux system. To facilitate morphologic control, we inv

This paper demonstrates the production of 〈00l〉-oriented CuO-doped (K0.476Na0.524)NbO3 (KNN) piezoelectric ceramics with a polymorphic phase transition (PPT) temperature greater than 180 °C by templated grain growth (TGG) using high aspect ratio
