The invention relates to a production method of a low-
voltage and
voltage-sensitive ZnO
ceramic material with a laminar structure and a resistance that is produced by the ZnO
ceramic material, and the invention belongs to the technical field of the production of electrical apparatus elements and materials. One group of raw materials is the mixed material that consists of ZnO and any
oxide powder that is added into ZnO and selected from the oxides nano ZnO and
doping elements of Bi, Al, Fe, Eu, Pr, La, Ce, Nd, B, Si, Mn, Cr, Co, Pb and Ti; the other group of raw materials is the mixed material that does not have addition elements or comprises ZnO that is blended with part of the oxides that are selected from the oxides of Al, Ti, Mn, Cr and Co; the two groups of
powder materials are placed into a mold according to a certain proportion, then pressed, molded and gradually heated, and heat-preserved
colloid discharge and heated agglomeration are implemented, thus obtaining the low-
voltage and voltage-sensitive ZnO
ceramic material with the laminar structure; the
surface processing of the ZnO ceramic material is implemented, silver is burned on the surface of the ZnO ceramic material by electrodes, and the ZnO ceramic material is tested and encapsulated, thus obtaining the product. The low-voltage and voltage-sensitive ZnO ceramic material with the laminar structure has the advantages of simple technique, lower cost, good performance and wide application range, and the resistance that is produced by the ZnO ceramic material has good
repeatability, stability and consistency, as well as remarkably improved
electric parameter values.
