Abstract: For the production of tube-shaped mouldings of high-temperature superconductor material based on oxides of bismuth, calcium, strontium and copper, a homogeneous melt of the oxide mixture is allowed to run in a predetermined stoichiometry at temperatures from 900 to 1100 DEG C into a casting zone rotating about its horizontal axis. The solidified moulding is taken out of the casting zone and heat-treated for 4 to 150 hours at 700 to 900 DEG C in an oxygen-containing atmosphere. A plant for producing tube-shaped mouldings consists of a rotatably mounted mould (4, 9) which is provided at least on one end face with an end ring 6 reducing its free cross-section, a casting chute 7 protruding into the interior of the mould (4, 9) and a crucible 8 which is arranged above the casting chute 7 and through which the casting chute 7 can be charged with melt.

Abstract: HOE 91/H 016 K Process for the preparation of fullerene In the process for the preparation of a C60/C70 mixture, known as fullerene, by vaporization of carbon under pressures of 0,05 to 3 bar, condensation of the gaseous carbon on cooled zones with the formation of a fullerene/carbon black mixture and separation of the fullerene from this mixture, the vaporization and condensation are carried out in oxygen-containing gases from the group comprising CO, CO2 and O2 or mixtures thereof.

Abstract: To produce tubular molded parts made of high-temperature superconductor material based on oxides of bismuth, calcium, strontium and copper, a homogeneous melt of the oxide mixture with a specified stoichiometry is allowed to run at temperatures of 900 to 1100.degree.C into a casting zone rotating about its horizontal axis. The solidified molded part is removed from the casting zone and it is annealed for 4 to 150 hours at 700 to 900.degree.C in an oxygencontaining atmosphere. A plant for producing tubular molded parts comprises a rotatably arranged mold (4, 9) which is provided at least at one end face with a front plate 6 which reduces its free cross section, a runner 7 extending into the interior of the mold (4, 9) and a crucible 8 arranged above the runner 7 which is capable of feeding the runner 7 with melt (cf. Fig. 2A).
