Technical Field

The invention relates to the field of soft magnetic material manufacturing, in particular to a soft magnetic powder material.

Background

Soft magnetic material, meaning that when magnetization occurs at Hc no greater than 1000A/m, such material is called soft magnet. Typical soft magnetic materials can achieve maximum magnetization with a minimum external magnetic field. The soft magnetic material is a magnetic material having a low coercive force and a high magnetic permeability.

With the development of science and technology, electronic components for electronics and communication put forward higher requirements on the coercive force and the magnetic conductivity of soft magnetic materials, and soft magnetic powder materials in the prior art cannot meet the special requirements of the existing electronic component industries for electronics and communication.

Disclosure of Invention

The invention provides a soft magnetic powder material to solve the technical problem that the soft magnetic powder material in the prior art cannot meet the special requirements of the existing electronic and communication electronic component industry.

The technical scheme adopted by the invention for solving the technical problems is as follows: the soft magnetic powder material comprises the following components in percentage by mass: 45-50% of ferric oxide, 10-15% of zinc oxide, 6-7.5% of calcium oxide, 5.5-6.5% of pure chromium, 5-7% of pure silicon and the balance of iron and additives.

Further: the purity of ferric oxide in the components is more than or equal to 99.9 percent; the purity of the zinc oxide is more than or equal to 99.5 percent; the purity of the calcium oxide is more than or equal to 98.5 percent.

Further: the additive comprises 500-800 ppm of calcium carbonate, 100-400 ppm of silicon dioxide and 100-400 ppm of polyethylene glycol.

The soft magnetic powder material has the beneficial effects that the soft magnetic powder material has low coercive force and high magnetic conductivity, and can meet the special requirements of industries such as automotive electronics, electronic components for communication, household appliances and the like.
