Abstract

A preparation process for a MnZn soft ferrite material having an ultra-low value loss and a high uQ. The manufacturing process is: (1) powder: (1.1) powder formulation; (1.2) powder moisture content technology; (2) spray granulation; (3) pre-sintering; (4) mixing grinding granulation; (5) forming; (6) sintering; (7) detection; (8) vacuum coating. The uQ product is increased from the current industry and market level of around six hundred and fifty thousand to around one million, thereby enabling the MnZn soft ferrite material to have superior performance.

Description

Technical field: [0001] The invention relates to the characteristics of an ultra-low value loss high μQ-MnZn soft ferrite material and a preparation method thereof, belonging to the high-end technical field of soft ferrite materials. Background technique: [0002] Soft magnetic ferrite is widely used in many fields such as household appliances, network communications, automotive electronics, aerospace, military and national defense. In recent years, its application fields have also been deepened, and the performance requirements for soft ferrites have also continued to increase and strengthen. [0003] High μQ materials and high Bs materials originally used for low magnetic flux density (weak current) and high magnetic flux density (strong current) have overlapped and merged with each other, and new materials including high u materials have emerged that combine all characteristics. Suitable for both IT electronics and power electronics. Its main features are two high, two ...
