Potassium niobate derived from a novel chemical solution

Molten salt synthesis of K4Nb6O17, K2Nb4O11and KNb3O8crystals with needle- or plate-like morphology

“…To the best of our knowledge the most recent phase diagrams in the systems Nb 2 O 5 -KNbO 3 and Nb 2 O 5 -NaNbO 3 are reported by Irle et al, 14 which also take into account the previous studies by Appendino et al 15 and Jaffe et al 16 Several routes have been used to synthesize compounds in this system, e.g. hydrothermal synthesis, [17][18][19] chemical synthesis 20,21 and molten salts synthesis (MSS). [22][23][24] MSS allows great flexibility in the adjustment of several synthesis parameters such as temperature, time, salt composition and weight ratio between salt and oxides in order to obtain the desired characteristics of the synthesis product.…”

Ferroelectric lithium tantalate thin film derived from peroxide

“…The reaction of H 2 O 2 aqueous solution with potassium niobate alkoxide has been analyzed in the preparation of potassium niobate peroxide precursor [13,14]. The reaction of H 2 O 2 aqueous solution with lithium and tantalum alkoxide should be similar.…”

Synthesis of KNbO3Films from K2NbO3F Solution on Oxide Substrates

“…KN crystal is also in famous that solid-state sintering is difficult for the synthesis. Thus chemical solution deposition was tried to synthesize KN by us [3,4]. In recent years, Sato group [5][6][7][8] and Komatsu group [9,10] reported KN with low temperature phase could be synthesized from K 2 NbO 3 F (KNF) aqueous solution.…”
