Description

technical field [0001] The invention belongs to the technical field of 3D printing ceramics, in particular to a method for 3D printing magnetic ceramics, and further discloses the magnetic ceramics prepared by the method. Background technique [0002] Magnetic materials usually refer to substances that can directly or indirectly generate magnetism from transition elements such as iron, cobalt, nickel and their alloys. They are functional materials with a wide range of uses. Modern magnetic materials have been widely used in our lives. For example, permanent magnet materials are used as motors, core materials used in transformers, magneto-optical disks used as memories, and magnetic recording floppy disks for computers. It is closely related to all aspects of automation, automation, mechatronics, national defense and national economy. [0003] Magnetic materials can be divided into soft magnetic materials and hard magnetic materials according to the difficulty of demagnetiza...
