摘要： The invention provides a method of making a composite beta-alumina artifact, such as a separator tube for an electrochemical cell, comprising two beta-alumina portions which are sealed together in a sealing zone, namely an inner portion and an outer portion which extends peripherally around the inner portion and embraces it in the sealing zone. The method comprises pressing the inner and outer portions from powders which, when sintered, shrink and form integral beta-alumina artifacts. The portions are then arranged so that the outer portion extends around the inner portion and embraces it in a sealing zone. The portions are then sintered to cause them to seal together hermetically in the sealing zone while converting each of the portions into a beta-alumina artifact. The portions are made so that the outer portion undergoes a greater degree of shrinkage during sintering than the inner portion and the portions are pressed so that the spacing between the portions where the outer portion extends around and embraces the inner portion is such that, upon sintering, the outer portion shrinks on to the inner portion to provide a hermetic peripheral seal between the portions.
摘要翻译：本发明提供一种制备复合β-氧化铝伪影的方法，例如用于电化学电池的隔离管，包括两个β-氧化铝部分，密封区域密封在一起，即在外围延伸的内部部分和外部部分围绕内部部分并将其包围在密封区域中。该方法包括将粉末的内部和外部部分压制成粉末，其在烧结时收缩并形成整体的β-氧化铝假象。然后将这些部分布置成使得外部部分围绕内部部分延伸并且将其包围在密封区域中。然后将这些部分烧结，使得它们在密封区中密封在一起，同时将每个部分转变为β-氧化铝伪影。制造这些部分使得外部部分在烧结期间比内部部分发生更大程度的收缩，并且部分被按压，使得外部部分围绕并包围内部部分的部分之间的间隔使得在烧结时，外部部分收缩到内部部分，以在这些部分之间提供密封的周边密封。

摘要： The invention provides a high temperature rechargeable electrochemical power storage cell which comprises an alkali metal anode which is molten at the operating temperature of the cell. The cell has a cathode and a separator which separates the anode from the cathode and which is a conductor of ions of the metal of the anode. The surface of the separator which is exposed to the anode is at least partly enclosed by and in contact with a layer of particulate material which acts as a wick for the molten alkali metal of the anode. The material of the particles of the layer is electronically conductive and chemically inert at the operating temperatures of the cell to the alkali metal of the anode and to the separator, and the particles thereof are coated by a surface coating. The alkali metal of the anode, when molten, exhibits a contact angle with respect to said coating which is less than the contact angle exhibited by the molten alkali metal with respect to the material of the particles which underlies their coatings.

摘要： The invention provides a method of making a flattened solid electrolyte, e.g. .beta.-alumina, envelope for use as an electrode holder in an electrochemical cell. A mouldable mixture of the .beta.-alumina with a binder is formed into sheet material and two panels of the sheet material are joined together along their peripheral edges to form the envelope. Spacing and reinforcing means is provided between the panels to space them apart and to reinforce the envelope. The edges of the panels are joined together using pressure, heat and/or solvent, after which are envelope is heated to cure the binder, volatilize the cured binder and sinter the solid electrolyte.

摘要： A method of making beta"-alumina comprises dispersing in a precursor of aluminum oxide a member of the group comprising sodium oxide and its precursors, and dispersing in the precursor of aluminum oxide a spinel stabilizer which is a member of the group comprising spinel-forming oxides and the precursors thereof, to form a mixture. The mixture is then heated to a temperature at which at least some of the precursor of aluminum oxide is converted to beta"-alumina. The precursor of aluminum oxide is one which, when calcined in air by itself, has a calcination product which, when subjected to X-ray diffraction, displays a predetermined X-ray diffraction trace. The X-ray diffraction trace is one whose peak with the highest intensity in the 2 (theta) range of 44.degree.-48.degree. and whose peak with the highest intensity in the 2 (theta) range of 63.degree.-69.degree. respectively have maximum intensities and integrated intensities which comply with equations (I) and (II):A/S is greater than 0.03 (I);andB/S is greater than 0.04 (II).
