Description

Dotad uzywano dla celów zapalowych stopów ceru z takiemi metalami lub meta- Ioidami, które wskutek wysokiego punktu topliwosci (okolo 1800°C) przy tarciu lub skrobaniu wytwarzaja iskry zarzace. Iskry te gasna bardzo szybko i moga byc uzywa¬ ne tylko do zapalania latwo palnych ply¬ nów lub par, lecz nie mozna ich stosowac bezposrednio do zapalania papieru, bawel¬ ny, tytuniu lub t. p. materjalów.Celem niniejszego wynalazku jest o- trzymanie stopu umozliwiajacego przez tarcie lub skrobanie, zapalenie wspomnia¬ nych cial (papier, bawelna, tyton lub tym podobne). Nowy wynalazek polega na tern, ze cer lub metal zmieszany z cerem zostaje stopiony z takiemi cialami, które tworza (przy mniej wiecej 800°C) latwo topliwe szklo krzemowe, przyczem pojedyncze czasteczki lacza sie z linnemi w formie plynnych zarzacych sie kropel szkla, posia¬ dajacych duza sile zapalowa przy równo¬ czesnym stosunkowo dlugim czasie dzia¬ lania.Przy wytwarzaniu wymienionych sto¬ pów ceru, uzywa sie takich polaczen, wy¬ twarzajacych gaz, które daja latwo topliwe szklo olowiowe, sodowe lub potasowe, np. krzem, potas, wapn, bor, sód, cynk, glin, o- lów lub tym podobne.Jako szczególnie dobrze dzialajacym okazal sie dodatek mieszaniny olowiiii krzemu, potasu i wapnia, tworzacy krople szkla olowiowego z cerem o duzej sile za¬ palowej.Miedzy temi zwiazkami okazaly sie ja-ko najkorzystniejsze te polaczenia, które przy mechanicznej obróbce, np. przez tar¬ cie lub skrobanie, tworza przy stopieniu latwo plynne szklo olowiowe, zawierajace mniej wiecej 75—90% tlenku ceru i mniej wiecej 10—25% krzemianu olowiowego* Jako przyklady wytwarzania stopów ceru podlug niniejszego wynalazku podaje sie nastepujace polaczenia: przyklad 1. przyklad 2. przyklad 3. 80 g ceru 82 g ceru 82 g ceru 4 g potasu 3 g potasu 3 g sodu 4 g wapnia 5 g olowiu 3 g wapnia 2 g boru 2 g boru 2 g boru 10 g krzemu 8 g krzemu 10 g krzemu PLUntil now, cerium alloys with such metals or metalloids have been used for ignition purposes, which, due to their high melting point (about 1800 ° C), generate governing sparks when rubbing or scraping. These sparks go out very quickly and may only be used to ignite flammable liquids or vapors, but they must not be used directly to ignite paper, cotton, titanium or the like. The purpose of the present invention is to keep an alloy capable of producing by rubbing or scraping, inflammation of said bodies (paper, cotton, tobacco or the like). The new invention consists in the fact that the complexion or metal mixed with the ceremony is fused with such bodies, which form (at about 800 ° C) easily fusible silicon glass, because individual particles are combined with linnemia in the form of liquid, interfering glass droplets. Which give a high ignition power with a concurrent relatively long operating time. In the production of the cerium alloys mentioned, such gas-producing combinations are used which give easily fusible lead, sodium or potassium glass, e.g. silicon, potassium , calcium, boron, sodium, zinc, aluminum, lead or the like. The addition of a mixture of lead and silicon, potassium and calcium, which forms lead glass droplets with a high flame power ceremony, proved to be particularly effective. The most advantageous combinations are those which, when mechanically processed, e.g. by friction or scraping, easily melt into a liquid lead glass, containing about 75-90% cerium oxide and about 10-25% lead silicate * The following combinations are given as examples of the preparation of cerium alloys under the present invention: Example 1 Example 2 Example 3. 80 g of cerium 82 g of cerium 82 g of cerium 4 g of potassium 3 g of potassium 3 g of sodium 4 g of calcium 5 g lead 3 g calcium 2 g boron 2 g boron 2 g boron 10 g silicon 8 g silicon 10 g silicon PL

Claims
