    摘要： A process for producing a bonded article of ceramic bodies comprising steps of: machining the ceramic bodies to be bonded to form machined surfaces with average surface roughnesses (Ra) of not more than 0.2 .mu.m and flatnesses of not more than 0.2 .mu.m; applying solution containing a bonding aid on at least one of the machined surfaces; contacting the machined surfaces with each other to produce an assembly; and subjecting the assembly to a heat treatment to produce the bonded article. The roughnesses and the flatnesses may preferably be not more than 0.1 .mu.m. The bonding aid may preferably be a sintering aid applicable to at least one of the ceramic bodies. The ceramic bodies may preferably be one or more material selected from a group consisting of aluminum nitride and silicon nitride. The bonding aid may preferably be one or more bonding aid selected from a group consisting of a substance of yttrium and a substance of ytterbium. In the article, a layer rich in elements contained in a bonding aid is formed along the bonding interface of the article and ceramic particles are grown across the bonding interface.

    摘要： Oxygen sensor with a disc type solid electrolyte has the disc sealed in a shrinkable ceramic tube by the pressure which is developed and the surface glazing which takes place as the tube is fired. The tube is preferably formed of forsterite which can shrink about 25% during firing, thus causing the tube to become slightly bulged out in the region of the disc due to the interference fit produced by the shrinkage. The porous electrodes on the top and bottom surfaces of the disc are preferably omitted from a small region near one edge of the top and bottom surfaces but are continued as a stripe or band down the edge from a diametrically opposite portion of each surface, the stripes and unelectroded areas associated with the respective surfaces being spaced to prevent electrical shorting. The disc stripes are pressure bonded during firing of the tube to a pair of spaced lead stripes on the inside tube surface.
