Abstract: A ceramic electronic component includes a ceramic sintered body and an electrode provided on a surface of the ceramic sintered body. The electrode contains Ag. The ceramic sintered body contain glass material made of borosilicate glass. The glass material has closed pores and open pores therein. The closed pores and the open pores have diameters decreasing as being located away from the surface of the ceramic sintered body. This ceramic electronic component can prevent delamination of the electrode from the ceramic sintered body during a process of firing a green sheet.

Abstract: Sulfonic acid ester derivatives represented by the general formula (4) or (5) are produced by reacting an amino alcohol derivative represented by the general formula (1) or (2) with an organic sulfonyl halide represented by the general formula (3), in a mixed solvent composed of an aprotic organic solvent and water in the presence of a non-water-prohibiting inorganic base. This procedure can be carried out in a simple, easy, safe and economical manner while reducing the load on the environment. Wherein n represents an integer of 0 to 5, A represents a phenyl group, which may be substituted, R represents a methanesulfonyl, ethanesulfonyl, p-toluenesulfonyl or p-nitrobenzenesulfonyl group and X represents a chloride, bromine or iodine atom.

Abstract: Powders of BaCO.sub.3, TiO.sub.2, ZnO, etc. are mixed to each other at a predetermined ratio of quantity, calcined in an atmospheric air at 90.degree.-120.degree. C., and pulverized to obtain a calcined powder having an average grain size from 1 to 3 .mu. m. 0.1 to 20 parts-by weight of a powder having an average grain size from 0.1 to 1.5 .mu.m comprising a glass having a transition point of not higher than 450.degree. C. obtained by mixing powders of Pb.sub.3 O.sub.4, SiO.sub.2, Na.sub.2 O, etc. to each other, melting and then pouring into water and pulverizing the thus obtained glass is admixed to the calcined powder. The mixture is dried, pelleted by adding a resin and the pellet powder is molded into a cylindrical shape, applied with CIP (Cold isotactic press), and the molding product after the treatment is sintered in an atmospheric air at 850.degree. to 1000.degree. C. to obtain a dielectric ceramic sintered at low temperature. The resultant dielectric ceramic has high denseness and high unloaded Q value while maintaining .tau.f within a practical range.
