The present invention provides a method for preparing a neodymium - doped yttrium - iron garnet-based ceramic solidified body, which comprises the following procedures: According to the chemical formula of Fe 2 O 3 : Y 2 O 3 : Nd 2 O 3 =5:3-x:x/2, take the dried hematite, Y 2 O 3 and Nd 2 O 3 powder and mix , to obtain a mixed powder; mix the mixed powder and eutectic salt according to a certain mass ratio, add an appropriate amount of ethanol for grinding to obtain a precursor, and put the precursor into a drying box for drying; The body is placed in an atmosphere furnace and heated to 900-1100° C., and kept for 3 hours. After cooling to room temperature, the sintered powder mixture can be obtained. The preparation method of the neodymium-doped yttrium iron garnet-based ceramic solidified body has low synthesis temperature and high synthesis rate. |
