Abstract

1,139,223. Magnetic compositions. SIEMENS A.G. 13 Sept., 1966 [21 July, 1966], No. 40854/66. Heading H1H. A permanent magnet material comprises strontium ferrite SrOxFe 2 O 3 where x is is 4À1-6À5 containing 0À2-1À45% by wt. SrSO 4 and 0À2- 2À15% by wt. SiO 2 . Specific proportions of SrSO 4 and SiO 2 are given for particular values of x. The material may also include 5 or 10% by wt. Al 2 O 3 .
