The sodium niobate NaNb3O8: A novel lamellar oxide synthesized by soft chemistry

Energy storage mechanisms in vacancy-ordered Wadsley–Roth layered niobates

“…These various distributions of peak intensities per reection character suggest a dependence of morphology on synthesis route (e.g., molten salt, solid state, hydrothermal). 30 In several repetitions of the synthesis, there were variations in the phase purity of intermediate hydrates that resulted in a minor fraction of unidentied phase(s) (# 5% by volume) in addition to NaNb 3 O 8 (Fig. 3c).…”

“…‡ The product was isolated using hot distilled water and vacuum-assisted ltration (using Whatman Grade 50 hardened low-ash lter paper). 30 The hydrated sodium niobate was heated at 3 min À1 to 140 , held for 3 h, and furnace cooled to room temperature, resulting in NaNb 3 O 8 . 30…”

Preparation and Characterization of Self-Cleaning Glass for Vehicle with Niobia Nanosheets

“…The binding energies of Nb 3d 3/2 and 3d 5/2 increased with increasing heating temperature. It is guessed that the binding energy of Nb-O increases since Nb-O bond lengths of NaNbO 3 (23) are shorter than those of NaNb 3 O 8 (24). The binding energy of Nb 3d 5/2 of the sample heated at 550 °C was in good agreement with NaNbO 3 (25).…”
