Abstract
A low temperature sinterable oxide magnetic material prepared by adding 0.1 to 5% by weight of glass containing 3 to 50 mol % of Li.sub.2 O, 10 to 97 mol % of B.sub.2 O.sub.3 and 0 to 70 mol % of SiO.sub.2 to ferrite containing at least 0.5 mol % of Li.sub.2 O. Especially, when a glass containing 10-28 mol % of Li.sub.2 O, 34 to 66 mol % of B.sub.2 O.sub.3, and 15 to 45 mol % of SiO.sub.2 is used, the sintering temperature can be reduced to about 1,000.degree. C. or less.
