1. A ceramic article comprising three phases of:
an X-phase of a first oxide containing a first element;
a Y-phase of a second oxide containing a second element different from the first element; and a
Z-phase of a third oxide containing a third element different from the first element and the second element,
wherein the ceramic article is modeled by additive modeling,
wherein the first oxide is an oxide contained in the X-phase in a largest molar ratio, the second oxide is an oxide contained in the Y-phase in a largest molar ratio, and the third oxide is an oxide contained in the Z-phase in a largest molar ratio,
wherein the three phases form a eutectic structure with one another,
wherein an average particle diameter x of crystal grains forming the X-phase, an average particle diameter y of crystal grains forming the Y-phase, and an average particle diameter z of crystal grains forming the Z-phase satisfy relationships of z/x<0.5 and z/y<0.5, and
wherein the average particle diameter x and the average particle diameter y are each 5 μm or more.
