Description

Leuchtkörper für elektrische Erhitzung In Patent 6o9 i55 werden selektivstrahlende elektrische Leuchtkörper --beschrieben, bei denen der ganze Leuchtkörper oder wenigstens seine nach außen strahlenden Teile aus feinkörnigen nichtmetallischen Stoffen, @insbesondere Metalloxyden, besteht, deren. Korngröße etwa i tu, und darunter beträgt. Die Wirkung läßt sich nach der Erfindung dadurch .erhöhen, daß diese polykristallinen Körper in: porösem Zustande vorhanden sind, derart, daß die einzelnen Kristallilie sich nur iii möglichst wenigen `Punkten berühren. Die Feinheit des Korns braucht dann nicht so groß zu sein; statt dessen ist es zweckmäßig, mit möglichst einheitlichen Korngrößen zu arbeiten, weil bei Verwendung verschiedener Korngrößen die kleineren Körner die Zwischenräume zwischen den großen ausfüllen und so zur Bildung unerwünschter Berührungsflächen beitragen. Es sind dieselben Fälle denkbar, die in dem Hauptpatent beschrieben wurden, nur daß die aus feinem Korn aufzubauenden Bestandteile des Leuchtkörpers gleichzeitig poröse Struktur erhalten. Die porösen Schichten können entweder eine ganz lockere Struktur haben, etwa die eines leicht .abwischbaren Belages; sie können aber auch zu :einem fest zusammenhaltenden Körper gesintert sein. Die Porösität: der Schicht - kann z. B. durch Verwendung eines mit einer leicht verdampfbareu oder verbrennbaren Masse (Papierbrei) gemischten Oxyds erzeugt werden.Luminous body for electrical heating In patent 6o9 i55 are selective radiating electric filament --described in which the entire filament or at least its outwardly radiating parts made of fine-grained non-metallic materials, @in particular Metal oxides, whose. Grain size is about i tu, and below. The effect can .erhöhen according to the invention that these polycrystalline bodies are present in a porous state, in such a way that the individual crystalline parts only touch as few `points as possible. The fineness of the grain then needs not to be that big; instead, it is advisable to use the most uniform Grain sizes to work because when using different grain sizes the smaller ones Grains fill in the spaces between the large ones and thus contribute to the formation of undesirable Contact surfaces contribute. The same cases are conceivable as in the main patent were described, only that the components of the filament to be built up from fine grain at the same time preserved porous structure. The porous layers can be either one have a very loose structure, for example that of an easily wipeable floor covering; you can but also to: be sintered into a firmly cohesive body. The porosity: the layer - can e.g. B. by using one with an easily evaporable or Combustible mass (paper pulp) mixed oxide can be produced.
