Abstract
The present disclosure relates to a magnetic heating element, an induction heating-type adhesive including the same, and a method of preparing the magnetic heating element. The magnetic heating element according to an embodiment of the present disclosure has a composition with an atomic ratio represented by the following formula, (Ma1−x−yMbxFey)1Fe2−zMczO4, wherein: Ma is cobalt (Co), Mb is one or more of zinc (Zn), Copper (Cu), Manganese (Mn), and Magnesium (Mg), and Mc is one or more of samarium (Sm), yttrium (Y), cerium (Ce), europium (Eu), neodymium (Nd), and dysprosium (Dy); 0.01≤x<0.6, 0≤y≤0.4, x+y<1, 0≤z≤0.5; and the magnetic heating element has a grain size of 40 nm to 500 nm, and powder of the magnetic heating element has a particle size of 100 nm to 30 μm. Accordingly, the adhesive including the magnetic heating element may improve adhesive performance and provide high-speed bonding.
