Manufacturing method for a soft magnetic composite glass particles and soft magnetic composite material

摘要

eddy current loss is small, and to provide the glass particles can be produced a soft magnetic composite material of high strength. Glass particles for soft magnetic composite material total, for example, by mass% based on oxides, SiO ₂ and B ₂ O _{3 a} in more than 10%, B ₂ O ₃ 25% or less, made of crystallized glass containing ZnO 40 to 65%, an average particle size of 1~500nm a.
