Title:
METHOD FOR PRODUCING PRECIPITATED SUBSTANCES WITH CONTROLLED AMOUNTS OF DOPANT ELEMENT
Document Type and Number:
WIPO Patent Application WO/2011/148463
Kind Code:
A1
Abstract:
Provided is a method for producing precipitated substances, particularly metal compounds, the dopant element amounts of which have been controlled by the use of a device that processes fluid between the treatment surfaces of a processing part that can be made to approach/separate and which rotate relative to each other. Using the device that processes fluid between the treatment surfaces (1) and (2) of the processing part that can be made to approach/separate and which rotate relative to each other, the substance to be precipitated is precipitated by mixing a feedstock solution, wherein the substance to be precipitated is solublized in a solvent, with the precipitant solvent and with the dopant element or dopant element-containing substance solubilized in at least one solvent selected from the solvent of said feedstock solution, said precipitant solvent or a solvent other than that of said feedstock solution or said precipitant solvent. Precipitated substances with controlled dopant element amounts are obtained by controlling the solubility of the dopant element or dopant element-containing substance in the precipitant solvent.
