The microstructure and ferroelectric properties of (K0.5Na0.5)NbO3–LiNbO3 lead-free piezoelectric ceramics

Microstructure and Nanoscale Piezoelectric/Ferroelectric Properties in La2Ti2O7 Thin Films Grown on (110)‐Oriented Doped Nb:SrTiO3 Substrates

“…Actually, the research toward new ecological ferroelectric lead-free phases proves to be essential for the industry. Among the number of lead-free compounds already studied and developed, we can cite: simple and complex perovskite such as BaTiO 3 (BT), Ba 1Àx Sr x TiO 3 (BST), KNbO 3 (KN) and K 1Àx Na x NbO 3 (KNN), LiNbO 3 (LN) and NaBiO 3 (NB), [5][6][7] tungsten bronze oxides such as Sr 1Àx Ba x Nb 2 O 6 (SBN) and Ba 2 NaNb 5 O 15 (BNN), [8,9] bismuth layer-structured ferroelectrics (BLSF) such as SrBi 2 Nb 2 O 9 (SBiN) [10] and Bi 4 Ti 3 O 12 (BIT) [11] and A 2 B 2 O 7 layered perovskite structures such as Sr 2 Nb 2 O 7 (SNO) [12] and Nd 2 Ti 2 O 7 (NTO). [13] This list is not exhaustive.…”

Effect of heating rate on the structure evolution of (K0.5Na0.5)NbO3–LiNbO3 lead-free piezoelectric ceramics

“…After drying, the mixed powder was calcined in an alumina crucible at 850°C for 5 h. The calcined powders were ball milled again for 12 h, then dried and pressed into disks of 12 mm in diameter and 1.2 mm in thickness using PVA as a binder. After burning off PVA, the pellets were sintered at 1080°C [25,26] with variable heating rates of 2, 3, 4, 5 and 6°C/min.…”

Hard Template Synthesis of Nanocrystalline NaNbO3 with Enhanced Photocatalytic Performance

“…Perovskite structured NaNbO 3 has a variety of unique ferroelectric [17], optical [18,19], and photocatalytic properties [20][21][22][23]. Extensive work has been devoted to prepare NaNbO 3 with various nanostructures [18,19,[22][23][24][25].…”
