description 911,642. Magnetic compositions. PHILIPS ELECTRICAL INDUSTRIES Ltd. May 28, 1959 [May 31, 1958], No. 18219/59. Class 38 (2). A ferromagnetic garnet derived from yttrium iron garnet Y 3 Fe 2 Fe 3 O 12 is given by the formula Y 3 - -a-b Ca a Ce b Fe 2-m-n Ti m Mg n Fe 3 -x-y Six Bey O 12 , where and In manufacture mixtures of metal oxides or oxide-yielding compounds are ground and presintered once or several times, reground and finally sintered in an atmosphere having an oxygen content higher than air. The sintering processes take place between 1200‹ C. and 1500‹ C.
