A simple preparation procedure for the synthesis of sodium hexaniobate nanorods

Hydrothermal synthesis of NaNbO3 with low NaOH concentration

“…Alkaline niobates have attracted much scientific attention for their excellent nonlinear optical, ferroelectric, piezoelectric, electro-optic, ionic conductive, pyroelectric, photorefractive, selective ion exchange, and photocatalytic properties [1][2][3][4][5][6][7][8][9][10][11][12][13][14][15][16][17]. For example, lead-free potassium and sodium niobates are potential substitutes for lead zirconium titanate (PZT) as highperformance piezoelectric ceramics.…”

“…Cho synthesized (Na,K)NbO 3 thin films with chemical vapor deposition [2]. The synthesis of KNbO 3 has been widely investigated, while there are few papers on NaNbO 3 [3][4][5][6][8][9][10][11]16,18,23,24].…”

Hydrothermal synthesis of lead free piezoelectric materials

“…confirming the large presence of incorporated water/hydroxyl in the lattice; and signature bands in the 400-1000 cm −1 range -similar to previous works on sodium hexaniobate and are related to the Nb-O vibrational modes [171,175,244]. Comparing the normalized FTIR data, the larger (inverted) area under the curve for R = 13.3% samples compared to the R = 10% indicates that the former has more water/hydroxyl incorporation in the lattice.…”

“…Figure 44(a) shows normalized FTIR spectra taken from samples with majority hexaniobate phases (2 and 1 hour for 10% and 13.3% samples respectively). The spectra reveal the signature bands related to O-H stretching (3250 cm −1 ) and H 2 O bending (1600 cm −1 ) modes [171,175];…”

Hydrothermal synthesis and electrical properties of NaNbO3

“…Niobium(V) oxide is always the reagent used in high temperature synthesis [15][16][17]. Indeed NaNbO 3 particles were synthesized by using conventional mixed-oxide (CMO), molten salt synthesis (MSS), topochemical micro-crystal conversion methods (TMC) [18][19][20][21], and hydrothermal process [4,[22][23][24][25][26][27]. Liang et al reported the synthesis of micrometric truncated cuboids NaNbO 3 [4], NaNbO 3 were synthesized through calcining the Na 2 Nb 2 O 6 .…”
