Embodiment 1
[0034] A garnet ferrite material applied to a high-power phase shifter, the ferrite material is made of ingredients in the following weight ratios:
[0035]
Embodiment 2
[0037] A method for preparing a garnet ferrite material applied to a high-power phase shifter,
[0038] 1) Weigh the ingredients according to the following weight:
[0039]
[0040] The total weight is 3019 grams.
[0041] 2) One-time ball milling: add 3019 grams of ingredients weighed in step 1) into 1800ml of distilled water and 1800ml of alcohol and put them into a ball mill for 24 hours, at a speed of 75 rpm to mix the ingredients evenly, material (g): distilled water (m1): The ratio of alcohol (m1):ball (g) is 1:0.6:0.6:2.
[0042] 3) drying: drying the ball-milled ingredients in step 2) at 95°C.
[0043] 4) Sieving: Pass the dried powder in step 3) through a 30-mesh sieve.
[0044] 5) Pre-burning: the powder obtained in step 4) is pressed figure 1 According to the pre-burning curve, heat up and keep warm, uniformly heat up from room temperature to 200°C within 2 hours, from 200°C to 1200°C within 8 hours, keep at 1200°C for 5 hours, and then cool naturally with th...
