Title: Production of dielectric ceramic material
Inventor: CHIN SHIYOUMEI
IPC: H01B3/00
Filed: 1992-04-07
Abstract: PURPOSE:To provide the process for production of the dielectric ceramic material at a low sintering temp. CONSTITUTION:This process for production of the dielectric ceramic material consists in repetitively executing, a desired number of times, a stage for tentative calcining the raw material powder which can be made into the dielectric ceramic material and a stage for pulverizing the tentative calcined matter obtd. in this stage to form tentative calcined powder, the compaction molding the tentative calcined powder to a desired shape and sintering the green compact by heating. At least one time of the above-mentioned tentative calcining stages are executed at a high temp. of 0.75 to 0.85Tm and the raw material powder of the dielectric ceramics is brought into reaction to a dielectric phase in the stage of tentative calcination and the tentative calcined powder to be subjected to the compaction molding is made into superfine powder of submicron order. As a result, the sintering temp. is lowered by 200 to 300 deg.C and the formation of coarse crystal grains is prevented. In addition the selection of the electrode material to be mounted to the heating sintered body in a wide field taking the electrical conductivity into consideration is enabled by the lowering of the sintering temp.
