Abstract: The invention provides spacers for separating and supporting a faceplate structure and a backplate structure in a flat panel display, and methods for fabricating these spacers. Each spacer is typically made of ceramic, such as alumina, containing transition metal oxide, such as titania, chromia or iron oxide. Each spacer can be fabricated with an electrically insulating core and electrically resistive skins. The insulating core can be a wafer formed of ceramic such as alumina, and the resistive skins can be formed by laminating electrically resistive wafers, formed from alumina containing transition metal oxide, to the outside surfaces of the insulating core. Each spacer can also have a core of electrically insulating ceramic composition made of a ceramic containing a transition metal oxide in its higher oxide states, and electrically resistive outside surfaces made of a ceramic containing a transition metal oxide in lower oxide states.

An alumina layer that is green containing an alumina that is not sintered at a temperature ranging from 800.degree. to 1000.degree.

The ceramic green sheet is sintered into a sintered ceramic substrate. A porous alumina layer is formed on a surface of the sintered ceramic substrate. The glass contained in the sintered ceramic substrate is caused to flow to the inside of the porous alumina layer so that the part of the porous alumina layer filled with the glass is bonded to the sintered ceramic substrate.

C. or more in an atmosphere containing 10% or less by volume of oxygen after sintering the dielectric ceramic. Using a BaO--TiO.sub.2 --Nd.sub.2 O.sub.3 --Bi.sub.2 O.sub.3 based composition (.epsilon..sub.r =92, Qf=5000 GHz) as a dielectric, a coaxial type dielectric ceramic is produced by granulating calcined powder of the dielectric and then compacting the powder, followed by sintering. A dielectric resonator of .lambda./4 is produced by coating the dielectric ceramic with Ag paste at a position other than either the upper or lower side and then burning the paste. Thereafter, the electrodes(1,4) are formed by burning the paste at 400.degree. C. or more in an atmosphere containing 10% or less by volume of oxygen.

Abstract: Components whose palladium metal-containing constituent is not subject to delamination and which exhibit very good dielectric properties are obtained by means of a method of manufacturing a ceramic electronic component. The ceramic electronic component is essentially composed of a dielectric oxide ceramic and at least one palladium-containing component, and is obtained by firing and sintering of a green body containing an organic binder with the firing process including a first step in which the binder is removed from the binder-containing green body by means of a water-gas reaction in a water vapor-containing, essentially oxygen-free, atmosphere at temperatures between 20.degree. and 880 .degree. C., and a second step in which the dielectric oxide ceramic is re-oxidized in an atmosphere having an oxygen content of 10 to 100% by volume at a temperature in the range from 880 .degree. C. to 900 .degree. C.

Abstract: The present invention provides a method for controlling a firing shrinkage of a ceramic green body. The method includes the steps of: subjecting a ceramic powder to a pretreatment by which a spherical diameter (Rs) of the ceramic powder is adjusted to be 1 .mu.m or less, wherein Rs is expressed by an equation of Rs(.mu.m)=6/.rho. S (.rho. is a true density (g/cm.sup.3) of the ceramic powder, and S is a BET specific surface area (m.sup.2 /s) of the ceramic powder.); subjecting the ceramic powder to heat treatment at a specific temperature calculated in advance; molding the ceramic powder to obtain a ceramic green body; and firing the ceramic green body. A temperature for the heat-treatment is calculated of the basis of a correlation between calculative rates for firing and arbitrary selected temperatures.
