Abstract: A tubular target for cathode atomization does not have a backing tube and it is made of molybdenum or a molybdenum alloy. The target has an inner surface which is in contact at least in certain regions with a cooling medium, wherein at least one region of the inner surface is separated from the cooling medium by at least one protective device. By way of example, the protective device may be in the form of a polymer layer. The tubular target exhibits outstanding long-term stability.

Abstract: A crucible made of molybdenum or a molybdenum alloy having a molybdenum content of more than 95 at % for producing an oxide-ceramic single crystal. The inner side of the crucible is at least partially provided with a layer that contains at least one refractory metal and is formed with pores.

Abstract: A method for producing an electric lamp having a vitreous lamp bulb and a foil of molybdenum or a doped molybdenum alloy which is pinched in the lamp bulb includes post-treating the unfinished foil such that substantially non-contiguous, insular regions of material agglomerates are formed. The material agglomerates are formed of molybdenum, molybdenum alloys, titanium, silicon, an oxide, a mixed oxide and/or an oxidic compound, with a vapor pressure of in each case less than 10 mbar at 2000° C. The substantially non-contiguous, insular regions are formed on at least 5 percent and at most 60 percent of the area of the foil surface. In this way, the adhesive strength between the foil and the glass and therefore also the service life of the lamp are significantly improved.

Abstract: The invention relates to an oxidation inhibitor coating for high-melting metals selected from the group of molybdenum, tungsten, tantalum and niobium and/or alloys thereof. The oxidation inhibitor coating comprises 1 to 14% by weight boron, 0.1 to 4% by weight carbon and the balance silicon.
