  • Publication number: 20180277890
    Abstract: A solid electrolyte for all-solid-state lithium-ion secondary batteries, which is a sintered body having Li-La-Zr garnet phases having a garnet-type crystal structure, which is Li7La3Zr2O12, or Li7La3Zr2O12, partially substituted by at least one element selected from the group consisting of Nb, Al and Ta, and Li2+xC1?xBxO3 (0<x<0.8) phases, is produced by mixing raw materials comprising Li-La-Zr garnet and Li2+xC1?xBxO3 (0<x<0.8), molding the mixed raw materials, and sintering the resultant green body.

  • Patent number: 9190194
    Abstract: Provided is a semiconductor ceramic composition that is a lead-free semiconductor ceramic composition in which a portion of Ba in a BaTiO3-based oxide is substituted by Bi and A (in which A is at least one kind of Na, Li and K), the semiconductor ceramic composition having a region between a center portion and an outer shell portion within a crystal grain, in which when Bi concentration is measured in a radial direction within the crystal grain, the Bi concentration in the region is higher than both Bi concentration in the center portion and Bi concentration in the outer shell portion.

  • Publication number: 20150069308
    Abstract: Provided is a method for producing a lead-free, perovskite semiconductor ceramic composition which is capable of suppressing the temperature coefficient of resistance ? from becoming small, and obtaining stable characteristics. The method for producing a lead-free semiconductor ceramic composition in which a portion of Ba in a BaTiO3-based oxide is substituted by Bi and A (in which A is at least one kind of Na, Li and K), the method including: calcining a raw material for forming the semiconductor ceramic composition at 700° C. to 1,300° C.; adding an oxide containing Ba and Ti, which becomes a liquid phase at 1,300° C. to 1,450° C., to the calcined raw material; forming the same; and then sintering at a temperature of 1,300° C. to 1,450° C.

  • Publication number: 20060234021
    Abstract: A multi-layer ceramic substrate having an in-plane shrinkage ratio of 1% or less with 0.1% or less of unevenness, inorganic particles remaining on the external electrodes being 20% or less by mass as a percentage of one or more metals constituting inorganic particles per the total amount of one or more metals constituting the external electrodes and one or more metals constituting the inorganic particles, is produced by (a) preparing a slurry containing ceramic material powder and an organic binder to form low-temperature-sinterable green substrate sheets, (b) laminating the green substrate sheets after forming electrodes thereon, to produce an unsintered multi-layer ceramic substrate, (c) bonding a constraining layer comprising inorganic particles, which are not sintered at the sintering temperature of the unsintered multi-layer ceramic substrate and have an average particle size of 0.3 ?m or more, 0.
