  • Jig for calcining electronic component
    Patent number: 7601442
    Abstract: A jig for calcining an electronic component including a substrate 11 and a zirconia layer 12 coated on a surface of the substrate characterized in that the zirconia layer including one or more metal oxides forming a liquid phase is calcined for improving peel-off resistance and wear resistance to crystallize the liquid phase after the calcination. In the jig for calcining the electronic component, when the zirconia layer is formed by using an inexpensive method such as an application method, the zirconia layer is not peeled off from the substrate, and grains are not detached.

  • Electronic component burning jig
    Publication number: 20050257740
    Abstract: A jig for calcining an electronic component including a substrate and a zirconia surface layer formed on the substrate, wherein one of the skewness, the kurtosis, the central surface average roughness the wear resistance and the thermal shock resistance of the zirconia surface layer is specified to a certain range. Consequently, the jig for calcining the electronic component can efficiently conduct the calcination without deteriorating the properties of the electronic component to be calcined.

  • Electronic component burning jig
    Publication number: 20050252446
    Abstract: An electronic component burning jig comprising a base (11) and a zirconia layer (12) with which the surface of the base is characterized in that the zirconia layer containing one or more metal oxides forming a liquid phase is fired and the liquid phase (15) is crystallized after the firing to improve the separation resistance and wear resistance. Even when the zirconia layer is formed by a low-cost method such as coating, the zirconia layer is not separated from the base and no particle comes off the zirconia layer.
