Sintering annealing process for barium-cobalt-zinc-niobium system microwave dielectric ceramic
The invention discloses a sintering annealing process for barium-cobalt-zinc-niobium system microwave dielectric ceramic. The process comprises the following steps: putting an aluminum oxide sagger containing a barium-cobalt-zinc-niobium system microwave dielectric ceramic green body into a sintering furnace cavity for sintering to obtain microwave dielectric ceramic; cooling the microwave dielectric ceramic to an annealing temperature at a predetermined cooling rate, and annealing the microwave dielectric ceramic under the condition of the annealing temperature, wherein the preset cooling rate is 1.0-1.5 DEG C/min. The microwave dielectric ceramic obtained after sintering is cooled to the annealing temperature at the cooling rate of 1.0-1.5 DEG C/min, so that substances in the ceramic arerelatively fully transferred, and the ceramic orderliness is improved. The electrical performance of the obtained barium-cobalt-zinc-niobium system microwave dielectric ceramic is greatly improved.
