Description
Znane sa rózne srodki oslabiania rozpy¬ lenia drutów % wolframu, wzglednie usuwar nia ciemnego osadu, ujawniajacego sie jako skutek Tozpylenia.Dq tych srodków nalezy np. stosowanie substancyj wywolujacych halogeny, które w praktyce znacznego cisnienia pary nie po¬ siadaja, lecz które jeszcze wystarczaja, aby w lampach wywolac atmosfere halogenowa.' Inny sposób jest ten, ze polaczenia halo¬ genów, nie posiadajace znaczniejszego ci¬ snienia przy niskiej temperaturze, naklada sie cienkiemi warstwami w. sposób odpowie¬ dni na druti zarowy przed lub po przymoco¬ waniu tegoz na drazku i pózniej poddaje sie ie wyparowaniu. Uzywa sie do tego sól, kryolit i t. p. Równiez fluorek wapna jak i inne rozpusziczaLne w wodzie substancje byly juz do powyzszego celu proponowane.Dalsze udoskonalenie wynalazku osiega sie puzez uzywanie boraitów. Z tych ostatnich wyróznil sie szczególnie borat potasu. Na¬ kladanie warstw najstosowniej odbywa sie w mieszaninie z malemi ilosciami fosforu bezksztaltnego, niiamowrcie rozpyla sie su- spenlsje fosforu bezksztaltnego w rozpuszczal¬ nym boracie np. na drazek trzymajacy druty.Nastepnie w zwykly sposób po przeto¬ pieniu drutu, wypróznia sie lampe z powie¬ li za, nie przepuszczajac przyton pradu elek¬ trycznego. Prad zas przepuszcza sie dopiero po zalutowaniu lampv\ przyczem borat i fos¬ for sie ulatniaja. PLVarious measures are known to reduce the atomization of tungsten% wires, or to remove the dark deposit, which appears as a result of Dusting. These measures include, for example, the use of halogen-inducing substances, which in practice do not have a high vapor pressure, but which are still sufficient. to create a halogen atmosphere in the lamps. ' Another method is that the connections of the halogens, which do not have any significant pressure at low temperature, are thinly layered in a manner that responds to the razor wires before or after attaching them to the bar and then evaporated. For this purpose, salt, cryolite, etc. are used. Also, calcium fluoride and other water-soluble substances have already been proposed for this purpose. A further improvement of the invention is achieved by the use of boraites. Of the latter, potassium borate stands out in particular. Layering is most conveniently carried out in a mixture with small amounts of formless phosphorus, and the suspenls of formless phosphorus are atomized in a soluble borate, for example on a stick holding the wires. But not letting a drop of electric current pass. The current is passed only after the lamps are soldered with borate and the phosphorus evaporates. PL
