Abstract

The invention discloses microwave dielectric ceramic powder and a preparation method thereof, microwave dielectric ceramic and a microwave component. The microwave dielectric ceramic powder is the microwave dielectric ceramic powder with a dielectric constant of 20 and a ceramic quality factor value of more than 80000. The microwave dielectric ceramic powder comprises powder, and the powder comprises titanium dioxide, magnesium oxide, zinc oxide, calcium titanate, zirconium dioxide and a trace amount of additive MnSO4. H2O according to the weight part ratio of 270: 155: 40: 30: 5. Compared with a common ceramic raw material with a dielectric constant of 20, a higher Q value and a more stable temperature coefficient can be achieved, and QxFo [ceramic quality factor] is increased from original 58000 to 80000 or above. The invention further discloses a preparation method of the microwave dielectric ceramic powder, microwave dielectric ceramic applying the microwave dielectric ceramic powder and a microwave component.

Description
