Abstract

944,745. Magnetic compositions. STANDARD TELEPHONES & CABLES Ltd. July 6, 1962 [July 10, 1961], No. 26062/62. Heading H1H. A ferromagnetic ferrite material with high permittivity and suitable for loading a coaxial telecommunications cable is formed by mixing an additional oxide component with a starting mixture of metal oxides having the formula xFe 2 O 3 yNiO zZnO t CoO, where 52# x #60, 15 # y # 48, 0 # z # 33, 0 # t # 5, before sintering, the additional component comprising 0.05-5% by weight of one or more of SiOg, SnO a , ZrOg, Ta 2 O b . In examples oxides of Fe Ni Zn and Co are mixed with an additional oxide, ground and sintered at 1250‹ C. for 2 hours in Og, being then cooled in Og over 15 hours.
