The invention provides a microwave dielectric ceramic, a preparation method thereof and a 5G base station, wherein the microwave dielectric ceramic is MO-doped Mg 0.964 Ca 0.336 TiO 3 The expression mode of the chemical composition is as follows: mg (magnesium) 0.964 Ca 0.336 TiO 3 -xMO (i); wherein MO is La 2/3 O、Al 2/3 At least one of O, ZnO, CeO, SmO, MnO and CoO; mg (magnesium) 0.964 Ca 0.336 TiO 3 The molar ratio to MO was: mg (magnesium) 0.964 Ca 0.336 TiO 3 : MO is 1: x; x is 0.001 to 0.05. The microwave dielectric ceramic provided by the invention is Mg 0.964 Ca 0.336 TiO 3 On the basis of the composite material, MO is doped, and the MO and the magnesium-calcium titanium matrix ceramic are compounded, so that the electrical property and the reliability of the ceramic can be improved, and the sintering temperature of the ceramic can be effectively reduced. |
