How different is mechanical activation from thermal activation? A case study with PZN and PZN-based relaxors

Study of the Process of Mechanochemical Activation to Obtain Aurivillius Oxides with n=1

“…The formation of compounds by mechanochemical activation, which cannot be obtained by conventional solidstate reactions, and the absence of other phases usually involved in those reactions, have been reported recently in other systems (28). According to previous results, it seems that the natural trend of mechanoactivated oxides of the Aurivillius family is the formation of new, non-previously synthesized #uorite phases (25), like the Bi VO and Bi MoO #uorites in this study.…”

Using Infrared Spectroscopy to Identify New Amorphous Phases - A Case Study of Carbonato Complex Formed by Mechanochemical Processing

“…Therefore, the amorphous phase represents a transitional phase of the reaction. (Wang et al, 2000a(Wang et al, , 2000bKuscer et al, 2006). In order to understand mechanochemical reactions, it is thus indispensable to analyze more closely the transitional amorphous phase.…”

Progress in synthesis of ferroelectric ceramic materials via high-energy mechanochemical technique

“…Secondly, it takes place at room temperature in well sealed containers, thus effectively alleviating the loss of the volatile components, such as lead, bismuth and lithium. This is of particular interest to the synthesis of ferroelectric materials, since most ferroelectric ceramics contain either lead (Pb) [38][39][40][41][42][62][63][64][65][66][67][68][69][122][123][124][125][126][127][128][129][130][131], bismuth (Bi) [188,[191][192][193][194][195][196][197][198][199][200][201][202] or lithium (Li) [213] as the major component. Furthermore, due to their nanometer scale size and very high homogeneity, the mechanochemically derived ceramic powders demonstrate much better sinterability than those synthesized by the conventional solid-state reaction and wet-chemical processes.…”
