    摘要： .beta.-zinc diphosphide monocrystals (.beta.-ZnP.sub.2) (whiskers) having a diameter of at least 7 mm are made. To this end, a quartz ampoule is filled up to 70-90% its volume with polycrystalline .beta.-ZnP.sub.2 ; the ampoule is sealed and drawn in upright position at a velocity of 0.5-2.5 mm/day during a period of 24-120 days through a kiln; the temperature outline from below to above in the kiln is defined by a lower inlet temperature of 580.degree.-780.degree. C., a mean maximum temperature of 800.degree.-950.degree. C. and an upper outlet temperature of 350.degree.-400.degree. C.; the ampoule coming from the furnace is crushed and .beta.-ZnP.sub.2 condensed into a monocrystal via the gas phase by sublimation into the upper ampoule portion is removed.

    摘要： The present invention provides a process for the currentless deposition oflectropositive metal layers on to appropriate less electropositive metals by contacting an object to be coated with a coating bath, wherein a coating bath is used which contains a metal complex obtained by reacting a monovalent electropositive metal halide with a base, which is capable of complex formation with the electropositive metal, and a hydrohalic acid.The present invention also provides a coating bath for the currentless deposition of electropositive metal layers on to less electropositive metals, wherein said bath contains an electropositive metal complex obtained by reacting a monovalent electropositive metal halide with a base which is capable of complex formation with the electropositive metal and a hydrohalic acid.Furthermore, the present invention provides an electropositive metal complex, obtainable by the reaction of a monovalent electropositive metal halide with a base which is capable of complex formation with the electropositive metal and a hydrohalic acid, followed by precipitation from the reaction mixture.
