Abstract
A solid composition according to the present disclosure is a solid composition to be used for forming a functional ceramic having a crystal phase, and contains an oxide constituted by a crystal phase different from the crystal phase of the functional ceramic at normal temperature and normal pressure, and an oxoacid compound. The oxoacid compound preferably contains at least one of a nitrate ion and a sulfate ion as an oxoanion. Further, the oxide preferably has a crystal grain size of 10 nm or more and 200 nm or less.
