A turbine blade and a method for its production. In order to protect the turbine blade from being damaged by particles carried in the gas, surfaces of the turbine blade are melted down to a predetermined depth in order to form a defined amorphous region on a crystalline structure of a base material. The surfaces are then cooled down at a predetermined temperature reduction rate per unit time.

A Deglor furnace includes heating elements each having a heater rod being surrounded by a protective tube. The protective tube is mounted on a ceiling of the Deglor furnace and is run through an opening in the ceiling into the interior of the Deglor furnace. Heat insulation of the ceiling which borders the opening is protected against corrosive gases from the interior by a shield.

Combustion plants and gas turbines have inner regions through which hot gases flow. A thermal insulation for the inner regions includes a fiber composite having a surface. A protection against destruction is disposed at the surface.

A heating element for a Deglor furnace includes a heating bar being surrounded by a protective tube. The protective tube is provided with a flange for mounting. The flange is formed by a separate ceramic ring or a metal clip and is permanently connected mechanically or chemically to an outer surface of the protective tube.

A high-temperature storage battery includes a housing and a stack of at least two storage cells disposed in the housing. Each of the storage cells has components loosely disposed on top of one another in the stack. The components include two reactant chambers, a planar ion-conducting solid electrolyte mutually separating the reactant chambers, and planar components serving as electrodes and bordering the storage cells toward the outside. At least one common resilient structural element presses the components of all of the storage cells together in a leakproof manner.

Individual rechargeable electric cell with an outer metal housing, an electrolyte tube open at the top arranged coaxially in the housing, liquid sodium in the tube, a current collector extending down through the open end of the tube into the sodium, an alpha-Al.sub.2 O.sub.3 ring at the open end of the tube, a first flexible flange which connects the current collector to the ring attached to the tube via an aluminum ring, a second flexible flange connected to the housing and to the alpha-Al.sub.2 O.sub.3 ring via another ring, and sulfur in the space between the housing and tubular electrolyte.
