Process and formulation to join ceramic forms while maintaining structural and physical characteristics across the bond surface
A ceramic bonding material including at least one fibrous material, a flux agent and a thickening agent wherein the ceramic bonding material fired at a set temperature to bond the two adjacent substrate faces.
SENSOR ELEMENT, GAS SENSOR, AND METHOD FOR MANUFACTURING SENSOR ELEMENT
A sensor element (10) having a laminate structure, and extending in an axial direction AX, the sensor element including a first and second ceramic layers (118B, 115) disposed apart from each other in a laminating direction; a third ceramic layer (118) intervening between the first and second ceramic layers in the laminating direction and having a hollow space (10G) formed therein; and an internal space which is the hollow space surrounded by the first ceramic layer, the second ceramic layer, and the third ceramic layer, wherein, at a periphery (10f) of the internal space, a fourth ceramic layer (181) containing as a main component a ceramic material different from that contained as a main component in the first and third ceramic layers intervenes between the first ceramic layer and the third ceramic layer which are exposed to the internal space. Also disclosed is a method for manufacturing the gas sensor element.
