Title:

METHOD FOR PRODUCING CERAMIC PRECURSOR

Document Type and Number:

Japanese Patent JP2010202641

Kind Code:

A

Abstract:

To provide a method for producing a ceramic precursor obtained by more dispersing an addition component into the main component.

In the method for producing a ceramic precursor, the total or a part of a first raw material including component (a), being the main component, and a second raw material including component (b), being an addition component, is made into complex ligands 12 and 14, each surrounded by bridging ligands; the first and second raw materials are added to a solvent including at least one of water, methanol and ethanol so that the total amount of the first and second raw materials is more excessive than the solubility of the solvent, thereby forming a suspending fluid; and the first and second raw materials each added in an excess amount are eluted and become to be in a high concentration state, thereby depositing the ceramic precursor 20 from the solvent.
