摘要

PROBLEM TO BE SOLVED: To provide a boride microparticle for insolation shield which is not spontaneously ignited in the air even when it is atomized.;SOLUTION: The boride microparticle is represented by general formula XB_m (wherein X element is at least one kind selected from Y, La, Ce, Pr, Nd, Sm, Eu, Gd, Tb, Dy, Ho, Er, Tm, Yb, Lu, Zr, Ba, Sr, and Ca; and m is 4m6.3) and contains at least one kind of additive element selected from Sb, Zn, Mg, Sn, B, Zr, Mo, Al, and Si. Spontaneous ignitability of the boride microparticle is removed by the additive element.;COPYRIGHT: (C)2006,JPO&NCIPI
