“…With sintering temperature increasing from 1400 to 1500°C, the terrace lateral growth and flatness increase as shown in Figure C,D. These observations correlate well with the terrace‐ledge‐kink (TLK) model . This interesting phenomenon has obvious morphological consequences as it can be clearly noticed from the SEM observations.…”

Direct ink writing (DIW) has become a widespread additive manufacturing technique for material engineering, but its application in lead‐free Ba0.85Ca0.15Zr0.1Ti0.9O3 piezoelectric ceramics from aqueous systems has not been reported so far to our knowledge. The main obstacle is the high extent of hydrolysis reactions undergone by the starting powders when dispersed in water, hindering the attainment of stable water‐based colloidal suspensions. This paper reports on the preparation of stable aqueous inks from a deagglomerated and surface‐treated powder synthesized by solid‐state reaction and on DIW of macroporous lead‐free piezoelectrics. Based on zeta potential and rheological measurements, the optimal amounts of processing additives (dispersant, binder, and coagulating agent) were selected to transform the initial fluid suspension to a viscoelastic paste with sufficient stiffness and stability for the printing process. Dielectric and piezoelectric properties of samples sintered under different temperatures were also investigated.

“…From a microscopic perspective, atomic diffusion during crystallization is energetically preferred first at K‐faces and then at S‐faces, causing the K‐faces to gradually disappear with the development of the sintering process . The terraces grow perpendicularly to the lateral motion of ledges.…”

“…Thus, HTSCs, CMR manganites, HLH perovskites demand three different approaches to achieve a proper morphology (Figure 1). For important devices utilizing these three perovskites, thin films, heterostructures or sandwiched structures have to be deposited (Zhang et al, 1996;Shiohara and Goodilin, 2000;Tretyakov and Goodilin, 2000;Tretyakov et al, 2004;Snaith and Hacke, 2018). CMR manganites (Pomerantseva et al, 2004) operate with a relative change of resistance under applied magnetic fields and this demands lateral transport of weak electrical currents while intergrain boundaries become highly important due to the effect of tunneling magnetoresistance (TMS).…”

“…No real applications are known so far for single crystals of the noted perovskites although their effective grown techniques are developed successfully (Goodilin et al, 1997(Goodilin et al, , 1998Shiohara and Goodilin, 2000;Zhumekenov et al, 2018). Probably, some of them seem to be prospective for light-emitting devices, photodetectors and X-ray detectors (Wei and Huang, 2019;Murali et al, 2020).…”

Widely spread crystal lattices of perovskites represent a natural flexible platform for chemical design of various advanced functional materials with unique features. An interplay between chemical bonding, defects and crystallochemical peculiarities makes the perovskite structure a "LEGO designer" utilizing natural features of chemical elements of the renowned Mendeleev's Periodic Table (PTE) celebrating its 150-year anniversary. In this mini-review, crystal chemistry and bonding features, physical and functional properties, preparation methods and tuning functional properties with periodicity "tools" of the PTE will be exemplified for legendary families of high-temperature superconductive cuprates, colossal magnetoresistive manganites and hybrid lead halides for a new generation of solar cells.

Simple analytical kinetic model of single-layer crystal-mother-phase interface is proposed, which provides results that can be compared directly with thermodynamic Jackson model. Both models are based on zeroth order approximation known from lattice-gas models, in which solid and fluid growth units are treated as mixed randomly in the interface layer. It is shown that the kinetic and thermodynamic approaches can lead to very similar predictions about growth mechanism. The parameters characterising growth conditions, obtained from these models, are significantly different from those obtained from Monte Carlo simulations applied to study stable states of single-layer interface. Monte Carlo calculations describe crystal growth in detail and their results can predict characteristic parameters for real experiment. Observed differences seem to be strongly influenced by the use of zeroth order approximation.
