Abstract
MATERIAL PARTICULADO PARA OBTENÇÃO DE COMPÓSITO MAGNÉTICO MOLE E PROCESSO DE PRODUÇÃO DE MATERIAL PARTICULADO PARA A OBTENÇÃO DE COMPÓSITO MAGNÉTICO MOLE. A presente invenção descreve um material particulado para obtenção de um compósito magnético mole (SMC), este material que compreende partículas ferromagnéticas revestidas por, ao menos, duas camadas de recobrimento sendo ao menos uma camada de nanopartículas óxidas e ao menos uma camada vítrea, ditas camadas de recobrimento promovendo uma maior continuidade, homogeneidade e adesão dos revestimentos isolantes sobre as partículas ferromagnéticas. A presente invenção refere-se ainda a um processo de produção de material particulado para obtenção de compósito magnético mole (SMC).
