Problems solved by technology

However, no matter what kind of improvement is made in the process of the inherent properties of the finished powder, it is difficult to achieve a large improvement in the performance of the product's magnetic permeability and saturation value.
Therefore, the effect is not ideal, and because of the addition of new process steps, the preparation process is more cumbersome. In addition, the subsequent coating of the original powder is always difficult to achieve the uniformity and effect of the original coating, and when the raw material is replaced, the original The coating process may not be fully used

Abstract

The invention belongs to the field of production raw materials of microelectronic products, and particularly discloses a method for improving metal soft magnetic characteristics. The improvement method comprises the following steps: weighing A-type powder, B-type powder and C-type powder, mixing the powders according to different proportions by weight to obtain mixed powder, and doping the mixed powder into metal soft magnetic powder; weighing an adhesive according to a weight ratio of 1.0-5.0% of the mixed powder; weighing a dispersing agent according to the weight ratio of 5.0-15.0% of the mixed powder; adding an adhesive and a dispersing agent into the mixed powder, and fully stirring the mixed powder to obtain finished product powder; and drying and curing the finished product powder.The powder A comprises an iron element, a carbon element and an oxygen element, the powder B comprises an iron element and a carbon element, and the powder C comprises an iron element, a silicon element and a boron element. The metal soft magnetic powder prepared by the method has the characteristics of high magnetic conductivity and high saturation value.

Description

technical field [0001] The invention belongs to the field of raw materials for producing microelectronic products, and in particular relates to a method for improving the soft magnetic properties of metals. Background technique [0002] With the rapid development of industries such as consumer electronics, automotive electronics, mobile communications and 5G, electronic components have also ushered in a wide range of demands, especially for microelectronics because they meet the requirements of miniaturization, precision and integration. Trend, so microelectronics products have a bright future. However, it is precisely because of these advantages of microelectronic products that the downstream application market is becoming more and more stringent on them, and the finished powder, as the source of electronic components, plays a decisive role in its performance. However, many properties of the finished powder depend to a large extent on the inherent properties of the constit...
