COMBINED MAGNETIC MATERIAL AND ITS PRODUCTION

摘要

PURPOSE:To obtain a combined ferrite material having a small magnetic loss in a high-frequency band and excellent temp. characteristics by using a compsn. contg. at least two kinds of ferrites different from each other in the temp. coefft. of magnetic loss. CONSTITUTION:Powdery starting materials for at least two kinds of ferrites different from each other in the temp. coefft. of magnetic loss are separately granulated, mixed, compacted and fired preferably at a temp. below the highest one of the calcining temps. of the powdery starting materials.
