En este trabajo se ha realizado la sintesis de precursores, oxidos mixtos, procesado de deramicos y dise\u00f1o de termistores nic basados en oxidos mixtos de mn-ni, mn-ni-li y fe-mn-ni con estructura espinela. Los oxidos mn3-xnix04 y fe2+5nixmn1-xs04 se han sintetizado a partir de soluciones solidas de formiatos. Los oxdis liymn3-x-yniy04 se sintetizaron por insercion con n-buli y por reaccion de li(hcoo)h2o y ni2mn1-z (hc00)22h2o. Los oxidos se sintetizaron en aire y\/o en atmosfera controlada entre 700 grados y 900 grados c dependiendo de la composicion de cada solucion solida. En todos los casos se observaron distribuciones estrechas de tama\u00f1os y morfolog\u00edas seudooctaedricas. los ceramicos se obtuvieron por adicion de solucion al 17% de pva y prensado a 4kbar posteriormente se sinterizan a 1100 grados y 1160 grados c (ni-mn y ni-mn-li) y 1200 grados y 1300 grados c (fe-mn-ni). Los ceramicos presentan elevadas densidades (93%-98%). las medidas electricas sobre los termistores mostraron que el minimo de resistividad para la serie mn-ni era aprox. 1600 cm (b=3900 k), mn-ni-li (0.05 mol li\/mol esp.) De 1700 cm (b=3800 k) y fe-mn-ni de 1300- 1600 cm (b=3800-4000 k).<\/p>\n
