Low-loss garnet microwave ferrite magnetic sheet and preparation method thereof
The invention belongs to the technical field of magnetic materials, and discloses a low-loss garnet microwave ferrite magnetic sheet and a preparation method thereof. The chemical formula of the low-loss garnet microwave ferrite magnetic sheet is Y<3-2a-b-c-d-e>Ca<2a+b+c+d+e)VGeSnTiZrInAlMnSiFe<5-a-b-c-d-e-f-g-h-k-sigma>O<12>, wherein a is more than 0 and no more than 1.55; b is more than 0 and no more than 1.4; c is more than 0 and no more than 0.6; d is more than 0 and no more than 0.6; e is more than 0 and no more than 0.6; f is more than 0 and no more than 0.6; gis more than 0 and no more than 0.6; h is more than 0 and no more than 0.1; k is more than 0 and no more than 0.1; and sigma is more than 0 and no more than 0.4. According to the low-loss garnet microwave ferrite magnetic sheet, a sintering aid SiO2 is added on the basis of an original low-loss microwave garnet microwave ferrite magnetic sheet for 4G communication, so the solid-phase reaction degree of a material is improved, porosity is reduced, material loss is further optimized, and the requirement of an isolator circulator for 5G communication on the microwave magnetic sheet is met.
