Abstract

The invention discloses a durable magnetic ceramic material. The durable magnetic ceramic material is prepared from 30-45 parts by weight of zirconium dioxide, 0.8-1.4 parts by weight of cobaltous sulfide, 1-4 parts by weight of ferriferrous oxide, 12-18 parts by weight of magnesium oxide, 10-20 parts by weight of titanium dioxide, 8-14 parts by weight of tin oxide, 2-4 parts by weight of polyethylene, 12-16 parts by weight of a curing agent, 10-15 parts by weight of carbonyl iron powder, 6-8 parts by weight of aliphatic polyurethane acrylate, 3-5 parts by weight of a coupling agent, 2-4 parts by weight of ferroboron, 1-2 parts by weight of holmium iron oxide, 1-2-2.3 parts by weight of cobalt and 2-4 parts by weight of iron oxide. The durable magnetic ceramic material has the advantages of high maximum magnetic energy product, high hardness, wear resistance, durability, excellent corrosion resistance, simple preparation processes and long service life.

Description

technical field [0001] The present invention relates to a durable magnetic ceramic material. Background technique [0002] Due to the low resistivity and high loss of metal and alloy magnetic materials, they are not suitable for high frequencies. Ceramic magnetic materials have high resistivity and can be applied in various forms ranging from commercial frequencies to millimeter waves, and have high high-frequency magnetic permeability, which is unmatched by other magnetic materials. There are many magnetic substances, but because the magnetic strength of ceramics is unmatched by other materials, a large number of them are used to make magnetic cores of inductors or transformers, and magnetic memory materials (such as coatings on soft and hard disks or magnetic tapes). film), various microwave components, and speakers, motors, etc. However, there are still many unsatisfactory magnetic ceramic materials on the market. At present, the magnetic temperature stability is poor, ...
