Embodiment 1
[0014] Embodiment 1: the manufacture method of the ferromagnetic core containing modified aluminum nitride, comprises the following steps:
[0015] (1) Pre-fired mixture: The molarity of the mixture A is Fe 2 o 3 78mol, MnO 16mol, ceramic powder 0.15mol, boron 0.07mol, titanium 0.05mol, aluminum hydroxide 0.30mol, modified aluminum nitride 0.17mol and bentonite 0.45 mol; Proportional component: 720ppm SiO 2 , 118ppm Nb 2 o 5 , 155ppm yttrium oxide, 115ppm tantalum oxide, 260ppm Al, 155ppm tin, 380ppm vanadium and 260ppm rubidium; Accurately weigh mixture A and mixture B respectively, use mixing tank to mix separately, and stir and mix at 4200 rpm for 2- After 3 hours, they are sent to the rotary kiln for pre-burning respectively, the temperature is controlled at 400°C, and the pre-burning time is 2-3 hours to obtain pre-fired mixture A and mixture B;
[0016] The preparation method of the modified aluminum nitride: mix 18kg aluminum nitride and alum in equal proportions,...
