“…Conducting MC processing for longer than 3.6 ks actually decreased sinterability as milling time increased. Although there are several instances of research on the MC synthesis of perovskite crystals, they all reported that longer MC processing time increased sintered density, [8,9] which contradicts our observation of decreased density. There are two conceivable reasons for this density decrease: (1) nonuniform sintering due to the presence of tightly agglomerated coarse powder (Fig.…”

“…Recently much work has been done on the synthesis of composite oxide ceramic powders created by the mechanochemical (MC) method, and there are reports on the various interesting phenomena that arise. [7] In particular Wang et al [8,9] performed MC synthesis of mostly Pb-based piezoelectric ceramics, and successfully obtained single-phase, high-density perovskite sintered materials with short milling time. There is also a report that sintered materials with sub-micrometer crystal grain sizes have been obtained from PLZT powder synthesized using the MC method.…”

“…El método de activación mecanoquímica y mecanosíntesis fue, en principio, aplicado para la síntesis de aleaciones, aunque poco a poco, desde no hace mucho tiempo, se va desarrollando para la preparación de óxidos metaestable o con propiedades optimizadas para diversos fines (37,38). En los últi-mos tiempos, la técnica de activación mecanoquímica ha sido también aplicada para la obtención de cerámicas ferro-piezoeléctricas relacionadas con los PZT (39,40), comprobándose una gran mejoría, en cuanto a la pureza de los materiales preparados y sus respuestas eléctricas.…”

“…In the case of ceramics processing, MA was successfully utilized to produce the materials in powder form with a nanocrystalline structure and high compositional homogeneity [24][25][26][27][28][29][30]. By employing this method, not only the desired structure can be directly formed without any further processing, but also the calcination process which is typically required in the solid state routes can be reduced [31].…”
