Abstract
Disclosed are a method for preparing a ceramic material including a compound of a formula of A2BxOy and a ceramic material prepared by the method. The method includes: mixing a first oxide of AOm and a second oxide of BOn to obtain a mixture, ball-milling the mixture until a particle size of the mixture is not greater than 1 μm with a medium selected from a group consisting of ethanol, acetone, deionized water and a combination thereof, to obtain a powder, drying the powder at a temperature in a range of 60 to 80° C., and sintering the powder with a laser irradiation having a laser wavelength of 980 nm, an irradiation power ranging from 50 to 1500 W and an irradiation period of 3 s to 8 min to obtain the ceramic material.
