Temperature-stable ceramic capacitor dielectric material Sr4GdTiNb9O30 and preparation method thereof
The invention discloses a temperature-stable ceramic capacitor dielectric material Sr4GdTiNb9O30 and a preparation method thereof. The method includes the steps: ball-milling SrCO3, Gd2O3, TiO2 and Nb2O5 in advance; refining raw materials; distributing the Sr4GdTiNb9O30 according to chemical concentration ratio; preparing the ceramic capacitor dielectric material Sr4GdTiNb9O30 by the aid of a solid reaction method after pre-burning and secondary ball-milling procedures. By the method, excellent temperature-stable dielectric ceramic materials can be obtained, the method is simple, moderate in cost and suitable for mass production, energy is saved, and emission is reduced.
