Preparation method of coated high-dielectric low-loss microwave ferrite material
The invention discloses a preparation method of a coated high-dielectric low-loss microwave ferrite material, and belongs to the field of electronic materials. According to the coated high-dielectric low-loss microwave ferrite material disclosed by the invention, the inner core NiCuZn ferrite is based on the NiCuZn ferrite material, and the Ir element is adopted for performing performance regulation and control, so that the microwave loss of the material is reduced, and excellent low-loss ferrite is obtained; the shell is a carbon sphere prepared by adopting a hydrothermal method, has a relatively good dielectric constant, is coated outside the ferrite, is good in uniformity, and improves the dielectric constant of the material. The coated high-dielectric low-loss microwave ferrite material prepared by the invention has a high dielectric constant (epsilon '= 30-60) and low microwave loss (ferromagnetic resonance line width delta H = 120-180Oe) in a microwave frequency band (9.56 GHz), and meets the application requirements of circulators, isolators and phase shifters in the microwave frequency band.
