Preparation method of bi-generation lizntimn spun ferrite substrate material

[0020] A preparation method of Bi-generation LiZnTiMn gyromagnetic ferrite substrate material, comprising the following steps:

[0021] Step 1: With Li 2 CO 3 , ZnO, TiO 2 , Mn 3 o 4 , Fe 2 o 3 and Bi 2 o 3 as raw material, according to Li 0.42 Zn 0.27 Ti 0.11 mn 0.1 Fe 2.1-x Bi x o 4 (x=0.002) The ratio of molecular formula is weighed, and preparation obtains initial powder;

[0022] Step 2: Perform wet ball milling for 4 hours according to the weight ratio of initial powder: deionized water: steel ball = 1:1.5:2.5, take out the obtained slurry and dry it at 90°C, put the dried powder Put it into a sintering furnace with an oxygen atmosphere, raise the temperature from room temperature to 840 °C at a rate of 2 °C / min and keep it for 2 hours, then cool down to room temperature naturally with the furnace to obtain a pre-sintered powder;

[0023] Step 3: Perform secondary ball milling on the calcined powder obtained in step 2, wherein the weight ratio of powder: ...
