摘要：
AN HEXAGONAL FERRITE COMPOSITION FOR MICROWAVE DEVICES IS OBTAINED BY DOUBLE SUBSTITUTION OF A PART OF THE FERRIC IONS IN A CONVENTIONAL ALKALINE-EARTH FERRITE (MO, 6RE2O3) BY COUPLES OF 1/2 (TI4+, NI2+) AND MN3+ OR BY TRIPLE SUBSTITUTION ADDING AL3+ TO THE TWO GROUPS ABOVE. THE MANUFACTURING PROCESS INCLUDES SINTERING OF SINGLE-CRYSTAL FLAKES OF THE FERRITE MATERIAL THE DIMENSIONS OF WHICH ARE NOT LARGER THAN .5 MM.
