Method for producing ceramic composite material, ceramic composite material, and light emitting device
Provided are a method for producing a ceramic composite material that has a high light emission intensity, a ceramic composite material, and a light emitting device. The method for producing a ceramic composite material, includes: preparing a green body containing a nitride fluorescent material having a composition represented by the following chemical formula (I) and aluminum oxide particles mixed with each other; and performing primary sintering the green body at a temperature in a range of 1,250° C. or more and 1,600° C. or less to provide a first sintered body:MwLn1xAyNz (I)wherein in the chemical formula (I), M represents at least one element selected from the group consisting of Ce and Pr; Ln1 represents at least one element selected from the group consisting of Sc, Y, La, Nd, Sm, Eu, Gd, Tb, Dy, Ho, Er, Tm, Yb, and Lu; A represents at least one element selected from the group consisting of Si and B; and w, x, y, and z each satisfy 0
