Abstract

830,208. Magnetic compositions. GENERAL ELECTRIC CO. April 21, 1958 [May 7, 1957], No. 12547/58. Drawings to Specification. Class 38 (2). A magnetostrictive mixed crystal ferrite material comprises 40-60 mol. per cent iron oxide, 0.1-1.0 mol. per cent vanadium oxide, less than 18 mol. per cent zinc oxide, the balance nickel oxide. The oxides are ground together in water, dried, powdered, moulded with or without a binder and sintered in air at 1300- 1450‹ C., preferably 1350-1400‹ C. A suitable heating cycle includes heating in seven hours to 1350‹ C., holding for four hours, and cooling in eight hours. Values of coupling coefficient of materials of different composition but all containing 0.5 mol. per cent of V 2 O 5 are tabulated.
