Abstract
Official abstract text for this publication.
A method for producing a solid composition according to the present disclosure is a method for producing a solid composition that is used for forming a functional ceramic having a first crystal phase. The method for producing a solid composition includes: producing an oxide composed of a second crystal phase different from the first crystal phase; and mixing the oxide and an oxo acid compound.
First claim
Opening claim text (preview).
What is claimed is: 1. A method for producing a solid composition used for forming a functional ceramic that has a first crystal phase, the method comprising: producing an oxide composed of a second crystal phase different from the first crystal phase, the producing of the oxide being performed by subjecting a mixture containing a plurality of types of metal compounds as a raw material to a heat treatment; and mixing the oxide and an oxo acid compound. 2. The method for producing a solid composition according to claim 1 , wherein the oxide and the oxo acid compound are mixed such that 0.001≤XO/XP≤4.00, wherein a content of the oxide in the solid composition is defined as XP [% by mass] and a content of the oxo acid compound in the solid composition is defined as XO [% by mass]. 3. The method for producing a solid composition according to claim 1 , wherein the oxo acid compound contains, as an oxo anion, at least one of a nitrate ion and a sulfate ion. 4. The method for producing a solid composition according to claim 1 , wherein the second crystal phase is a perovskite type crystal, and the first crystal phase is a cubic garnet type crystal. 5. The method for producing a solid composition according to claim 1 , wherein the second crystal phase is a cubic type crystal, and the first crystal phase is a perovskite type crystal. 6. The method for producing a solid composition according to claim 1 , wherein the second crystal phase is a YFeO 3 type crystal, and the first crystal phase is a garnet type crystal. 7. The method for producing a solid composition according to claim 1 , wherein the oxide has a crystal grain size of 10 nm or more and 200 nm or less. 8. A method for producing a functional ceramic, comprising: producing a solid composition by the method according to claim 1 ; and heating the solid composition at a temperature of 700° C. or higher and 1000° C. or lower.
