Abstract:
Boride particles represented by a general formula XB, (where X is at least one kind of metal element selected from Y, La, Ce, Pr, Nd, Sm, Eu, Gd, Tb, Dy, Ho, Er, Tm, Yb, Lu, Sr, Ca, and m is a number indicating an amount of boron in the general formula) are provided, wherein an amount of carbon included in the boride particles is 0.2% by mass or less, as measured by a combustion-infrared absorption method.
