This article aims to provide a comprehensive review of lead-free hybrid nano materials
based piezoelectric fillers. It narrates the basic concept of piezoelectricity and discusses the …

The emerging smart PVDF-based composites can compensate for the intrinsic property
deficiencies in either of their components. The properties of the composite are determined …

Abstract Dense (K, Na) NbO3 ceramics are successfully fabricated via the cold sintering
process at 350° C under a uniaxial pressure of 400 MPa for 4 h. Equimolar KOH and NaOH …

Through mixing the KMnO4 solution with K0. 5Na0. 5NbO3 (KNN) powders, cold sintering
process (CSP) was employed to fabricate high‐density Mn‐doped KNN green pellets and …

In view of industrial applications requiring high piezoelectric activity, KNN-based ceramics
face two key constraints: insufficient density and temperature sensitivity. To address these …

Abstract K 0.5 Na 0.5 NbO 3 (KNN) ceramics have been widely studied for high Curie
temperature (T c) and good electrical properties. The structural and electrical properties of …

Polycrystalline ceramics of KNbO 3 (KNO) were prepared via sol–gel (by acrylamide
polymerization), hydrothermal, and solid–state chemistry reactions. Pure orthorhombic …

Non-toxic lead-free potassium sodium niobate (K0. 5Na0. 5NbO3) ceramics were
manufactured by using solid-state reaction method. The influences of excessive alkali metal …

In this study, pure KNN and Ba/Sr co-doped KNN with and without nano-CuO (nCuO) as
sintering aid (0.5 mol%) were prepared by the solid-state method. The results showed that …
