摘要： The lithium niobate solution of the invention is a lithium niobate solution containing lithium niobate having a molar ratio of lithium and niobium Li/Nb of 0.8 or more and 2.0 or less and ammonium ions, and the particle size (D50) of the lithium niobate in the lithium niobate solution according to dynamic light scattering is 100 nm or less. Moreover, the method for producing a lithium niobate solution of the invention has a step of producing an acidic niobium solution containing niobium, a step of obtaining a precipitate slurry containing niobium by inverse neutralization by adding the acidic niobium solution to ammonia water and a step of obtaining a lithium niobate solution by maintaining a mixture of the precipitate slurry containing niobium and lithium hydroxide at 20°C to 100°C with stirring.

摘要： The present invention relates to a method for manufacturing a crystalline oxidic compound comprising an alkaline metal and a valve metal, to a crystalline oxidic compound as obtained by the method, and to its use as a ferroelectric material; as a coating material for electrode materials in batteries, specifically in solid-state batteries; or in digital printing, especially on a polymeric substrate.
Herein, the method for manufacturing a crystalline oxidic compound comprising an alkaline metal and a valve metal comprises the following steps:
a) mixing an alcoholate of an alkaline metal and an alcoholate of a valve metal in a composition of an oxygenated organic solvent and hydrogen peroxide at room temperature;
b) adding an acid selected from at least one of nitric acid or hydrochloric acid at room temperature, whereby a solution is obtained;
c) drying the solution at an elevated temperature of 50 °C to 150 °C, whereby a powder comprising the at least one crystalline oxidic compound comprising the alkaline metal and the valve metal is obtained.
This manufacturing method operates at a low ambient working temperature, especially below 200 °C, and, thus, allows a direct manufacturing of crystalline oxidic compounds without interaction with a substrate and/or on a substrate which is not capable of tolerating higher temperatures during the manufacturing of crystalline oxidic compounds without deformation and/or deterioration. A further advantage of the low ambient working temperature is that a diffusion of elements from the at least one crystalline oxidic compound as coating material into the substrate can be avoided.
