  • Magnetic Body, Curable Composition Comprising the Same and Manufacturing Method of the Magnetic Body
    Publication number: 20230154658
    Abstract: A magnetic body, a curable composition comprising the same, and a method for manufacturing the same are disclosed herein. In some embodiments, a magnetic body includes magnetic particles, and a surface treatment agent bonded to the surface of the magnetic particles, wherein the magnetic particles comprise crystals having a size in a range of 10 nm to 40 nm, wherein the magnetic particles have an average particle diameter in a range of 20 nm to 300 nm, and wherein the magnetic particles have a particle diameter variation coefficient in a range of 5% to 30%. The magnetic body may have an excellent calorific value, and at the same time, may maintain the calorific value uniformly. In the magnetic body, the calorific value characteristics may be freely adjusted. The curable composition of the present application can be easily cured by using a magnetic body that satisfies all the characteristics.
