Материал получают смешиванием исходных порошков в вибромельнице и обжигом при 750°С в течение 5 ч. Брикет дроб т и в смесь ввод т окись висмута с последующим помолом и прессованием . Прессованные сердечники спекают при 1150-1250°С в атмосфере технического кислорода.The material is obtained by mixing the initial powders in a vibrating mill and firing at 750 ° C for 5 hours. The briquette is crushed and bismuth oxide is introduced into the mixture, followed by grinding and pressing. Pressed cores are sintered at 1150-1250 ° C in the atmosphere of technical oxygen.
