Attempts are made to prepare the cermet-type ferrite, which is a new magnetic composite material composed of ferrites and magnetic alloys. The main conclusions from the present study are as follows.
(1) Sendust alloy and ferrites have no affinity of make complexes.
(2) The measurements of saturation flux density show a large value of about 8, 000 G. or more for the composite materials which are composed of carbonyl iron of 60wt.% or more and magnetite.
(3) Addition of B2O3 causes an enhancement of density, saturation flux density and resistivity.
