Abstract:
This invention relates to a formula of a VHF inductive chip material and its preparation method. There is not high performance low temp sintered ferrite materials at present so we have to use low dielectric ceramics as the medium instead to produce low inductance multi-chip inductors. The basis of the said material is a plane hexagon soft magnet ferrite matched with low temp combustion adjuvant processed by the solid phase reactance synthesis and the combustion adjuvant is applied with two times of doping VHF inductive material of excellent performance is got after ballmill, baking, preroast, ballmill, baking, granulation, formation sintering, realizing low temp sintering with temp below 900 deg.c.
