Abstract:
An improved method of sealing a ceramic part to a solid part made of ceramic, metal, cermet or a ceramic coated metal is provided. The improved method includes placing a bond agent comprising an Al 2 O 3 and SiO 2 based glass- ceramic material and organic binder material on adjoining surfaces of the ceramic part and the solid part. The assembly is heated to a first target temperature that removes or dissolves the organic binder material from the bond agent and the assembly is subjected to a second induction heating step at a temperature ramp rate of between about 100°C and 200°C per minute to temperatures where the glass- ceramic material flows and wets the interface between adjoining surfaces. The assembly is rapidly cooled at a cooling rate of about 140°C per minute or more to induce nucleation and re-crystallization of the glass-ceramic material to form a dense, durable and gas-tight seal.
Abstract:
A transparent laminate structure is provided that includes two transparent layers, a transparent interlayer, and an inorganic barrier layer. The two transparent layers each have an inner face and a side edge. The transparent interlayer is between and laminates the inner faces of the two transparent layers to one another. The transparent interlayer also extends over the side edges of the two transparent layers and laminates the inorganic barrier layer to at least the side edges of the two transparent layers.
Abstract:
A method for making a thin, free-standing ceramic sheet may include drawing a carrier film proximate a casting head and across a casting bed of a tape caster at a rate from about 2 cm/min to about 500 cm/min. Depositing a thin film of ceramic slip less than about 150 μm on the carrier film with the casting head. The ceramic slip may comprises a ceramic powder with an ultimate crystallite size of less than about 10 μm dispersed in a fluid vehicle such that the ceramic slip has a ceramic solids fraction of greater than about 20 % by volume. The deposited ceramic slip may be dried on the carrier film thereby forming a green ceramic sheet on the carrier film. After the green ceramic sheet is dried, the green ceramic sheet may be sintered.
Abstract:
Provided is method for producing a multilayer structure, one method comprising the steps of: - providing a laminate of a first electrode or electrode precursor layer, an electrolyte layer, and a second electrode or electrode precursor layer; - folding the laminate at least once; and - sintering the stack; - wherein the number of layers in the multilayer structure is at least 5. Also provided is a method for producing a multilayer structure, comprising the steps of: - providing an electrolyte layer; - applying a blocking layer on one edge of the electrolyte layer; - providing an electrode or electrode precursor layer directly on the electrolyte layer on the side of the electrolyte layer where the blocking layer has been applied so as to obtain a laminate; - stacking at least two laminates such that the electrolyte layer of each laminate being stacked is applied on the electrode or electrode precursor layer of the stack on which it is stacked; and such that the blocking layer of each laminate being stacked is on the horizontally opposite side of the blocking layer of the laminate on which it is stacked; and - sintering the stack; - wherein the number of layers in the multilayer structure is at least 5. The present invention moreover provides a multilayer structure, obtainable by the above methods.
