The aim of this review article on recent developments of mechanochemistry (nowadays
established as a part of chemistry) is to provide a comprehensive overview of advances …

The potassium sodium niobate, K0. 5Na0. 5NbO3, solid solution (KNN) is considered as one
of the most promising, environment-friendly, lead-free candidates to replace highly efficient …

Piezoelectric materials are an important functional material in the modern world because
they are capable of converting electrical energy into mechanical energy and vice versa …

The focus on piezoelectric ceramics based on the potassium sodium niobate system began
in 2004. After years of dedicated research, these materials can be considered one of the …

Synthesis and sintering of (K, Na) NbO 3 lead-free piezoelectric ceramics (KNN) were
carried out using conventional and microwave heating processes. Microwave calcination …

Coarsening and poor densification have hampered the progress to develop lead-free
piezoelectric ceramics based on K 0.5 Na 0.5 NbO 3 (KNN). Here, we present an aqueous …

Ferroelectric ceramics were discovered in the 1940s in polycrystalline barium titanate (von
Hippel et al., 1946; Wul & Goldman, 1945), since then, there has been a continuous …

A full set of elastic and electrical coefficients of (K, Na) NbO 3-based lead-free
piezoceramics with a nominal composition of Li 0.03 (K 0.48 Na 0.52) 0.97 (Nb 0.8 Ta 0.2) O …

Single phase nano-crystalline K 0.5 Na 0.5 NbO 3 (KNN) ceramic has been successfully
synthesized by the mechanochemical activation method. High energy ball milling was …

Interaction in the system of lithium carbonate–niobium pentoxide during mechanochemical
treatment in air and water has been studied. Prepared samples have been investigated with …
