CERAMIC MATERIAL AND METHOD FOR PREPARING THE SAME
A ceramic material including Co0.5Ti0.5TaO4. The ceramic material is prepared as follows: 1) weighting and mixing raw powders of Co2O3, TiO2 and Ta2O5 proportioned according to the chemical formula of Co0.5Ti0.5TaO4, to yield a mixture; 2) mixing the mixture obtained in 1), zirconia balls, and deionized water according to a mass ratio of 1:4-6:3-6, ball-milling for 6-8 h, drying at 80-120° C., sieving with a 60-200 mesh sieve, calcining in air atmosphere at 800-1100° C. for 3-5 h, to yield powders comprising a main crystalline phase of Co0.5Ti0.5TaO4; and 3) mixing the powders obtained in 2), zirconia balls, and deionized water according to a mass ratio of 1:3-5:2-4, ball-milling for 4-6 h, and drying at 80-100° C.; adding a 2-5 wt. % of polyvinyl alcohol solution to a resulting product, granulating, sintering resulting granules at 1000-1100° C. in air atmosphere for 4-6 h.
