The invention relates to a method for producing a product, to a crucible and to the use of a layer of crystalline silicon nitride, the product being formed from a material consisting mainly of carbon or of a ceramic material, the product being coated with surface layer by chemical vapor deposition (CVD), wherein the product is coated with a surface layer of at least semi-crystalline, preferably crystalline silicon nitride (SiN), the surface layer being formed on the product at a process temperature of more than 1100° C. to 1700° C.

Coated product and production method

A superconducting fiber of a superconducting fiber bundle includes a carrier fiber having an outer surface, and superconducting layers and separating layers alternatingly surrounding the outer surface of the carrier fiber and a method for producing the same.

Composite superconducting fiber

A superconducting fiber of a superconducting fiber bundle, in which a base layer of a carbide or oxide is applied to the outer surface of a carrier fiber and subsequently a superconducting layer is deposited on the base layer to which the superconducting layer adheres.

Superconducting fiber

A method for the application or impregnation of a highly adherent heat-barrier layer on a metal substrate comprising effecting chemical vapor-phase deposition of zirconium dioxide as a heat-barrier layer with infiltration by finely granular zirconium dioxide in a metal felt. The vapor-phase deposition with infiltration of the metal felt can take place, in particular, from zirconium chloride, preferably within a temperature range between 550.degree. C. and 750.degree. C.

Method of forming a heat-barrier layer on a metal substrate

A process for the production of a flexible superconductor comprising a carbon fiber having thereon a layer of niobium carbonitride, and an outer layer of a highly conductive metal. Initially, niobium is deposited on the fiber, and the niobium-coated fiber is then exposed to gaseous sources of carbon and nitrogen while the temperature is subsequently raised.
