Low-loss microwave ferrite material for LTCF phase shifter and preparation method of low-loss microwave ferrite material
The invention discloses a low-loss microwave ferrite material for an LTCF phase shifter and a preparation method of the low-loss microwave ferrite material, and belongs to the technical field of electronic ceramic materials. The microwave ferrite material comprises a main material and an auxiliary material, wherein the auxiliary material accounts for 0.01-2wt% of the mass of the main material; the main material is prepared from the following components in percentage by weight: 11.65 to 12.33 mol percent of Li2CO3, 17.61 to 22.18 mol percent of ZnO, 8.22 to 13.31 mol percent of TiO2, 1.85 to 1.96 mol percent of Mn3O4, 0.93 to 59.79 mol percent of Fe2O3 and 0.08 to 0.09 mol percent of Bi2O3; and the auxiliary material is rutile type or anatase type TiO2 with the particle size of 5-50 nm. The low-loss microwave ferrite material for the LTCF phase shifter, prepared by the invention, not only has a relatively low sintering temperature (less than or equal to 910 DEG C), but also has a narrow ferromagnetic resonance line width (less than or equal to 90Oe) and low dielectric loss (lt; 3 * 10 <-4 >), high saturation magnetization (gt; 3700 Gauss), a high remanence ratio (gt; 0.85) and a high Curie temperature (gt; 300 DEG C). The prepared microwave ferrite not only meets LTCF process requirements, but also has excellent magnetic performance of key substrate materials required by microwave devices such as low-loss phase shifters and the like.
