method of producing a high and mittelpermeablen mn - zn sn ti ferroferrits for a wide temperature and frequency range

摘要

increasingly, e.g. for rf multiplexed systems up and mittelpermeable ferrite asked in a broad frequency and temperature range, especially in a frequency range from 20 khz to 1 mhz and in the temperature range from about 40 to about + 80 degrees celsius optimally e insetzbar.in the erfindungsgemaessen ferritkomposition has surprisingly shown that a combination of zinnoxyd and titanoxyd, in the above limitations, especially at higher frequencies, e.g.between 100 khz and 1mhz, and relatively high curietemperatur particularly favorable to the verlustbeiwerte and overall ferriteigenschaften at all, for the function of the structural element in a wide frequency and temperature range are necessary if the ferrite on impact anfangspermeabilitaeten from about 1000 to 1800 aussintert,with the sintering and / or abkuehlbedingungen to choose, that an optimal compromise between goodness and constance secures. are probably higher anfangspermeabilitaeten is chosen, the frequency range, the highest gueten are adjustable to lower frequencies, inevitably delayed....u.s.w
