The invention provides a silicon ceramic material for a magnetic core, the magnetic core, a magnetic device and a preparation method. The silicon ceramic material comprises the following components: nano insulating particles, silane, organic acid, an auxiliary agent and a solvent, wherein the mass percent of the nano insulating particles is 10-25%; the mass percent of the silane is 20-30%; the mass percent of the organic acid is 1-5%; and the mass percentage of the auxiliary agent is 1-4%. Due to the excellent insulation and voltage resistance characteristics and the clamping of the high-temperature-resistant insulation particles, the magnetic resistance breakdown voltage characteristic of the magnetic ring is further improved, the magnetic loss of the magnetic ring is reduced, and the full-frequency impedance change is small under the impact of high pulse voltage. And the high-frequency application range of the nanocrystalline magnetic core is further widened. 本发明提供一种磁芯用硅合陶瓷材料、磁芯、磁性装置和制备方法，硅合陶瓷材料包括组分：纳米绝缘颗粒、
