PURPOSE:To obtain an inexpensive magnetic oxide material capable of being sintered at a low temp. and undergoing a slight deterioration in the magnetic characteristics by adding glass contg. Li2O and SiO2 to ferrite contg. Li2O. CONSTITUTION:To ferrite contg. >=0.5mol% Li2O is added 0.1-5wt% glass contg. 3-50mol% Li2O, 10-97mol% B2O3 and <=70mol% SiO2. Especially, by adding glass contg. 10-28mol% Li2O, 34-66mol% B2O3 and 15-45mol% SiO2, the sintering temp. can be reduced to <= about 1,000 deg.C, and a remarkable low temp. sintering effect can be produced. When the glass is added by >5wt%, the sintering temp. is hardly reduced, and the magnetic characteristics are unfavorably deteriorated on the contrary. |
