Garnet ferrite material applied to high-power phase shifter and preparing method thereof
The invention relates to a garnet ferrite material applied to a high-power phase shifter and a preparing method thereof. The garnet ferrite material is prepared from, by weight, 35-37% of Y2O3, 13-15% of Gd2O3, 1-3% of Al2O3, 1-3% of Mn2CO3 and 45-47% of Fe2O3; the method comprises the steps of weighing and mixing according to the weight ratio, primary ball milling, drying, screening, presintering, secondary ball milling, drying, pelletizing, pressing forming and sintering. Compared with a lithium ferrite material, the garnet ferrite material prepared by utilizing the method has the advantages of being high in density, small in porosity and small in effective line width and the like.
