Description

Insbesondere gegen alkalische Schmelzen beständiger Werkstoff Zusatz zum Patent 858376 Gegenstand des Patentes 858 3,76 ist ein insbesondere gegen alkalische Schmelzen beständiges Ofenfutter, das aus den Oxyden der Erdalkalien, wie Magnesiumoxyd oder Calciumoxyd, oder Gemischen :derselben und einem schützenden Überzug, im wesentlichen aus Erdalkalititanat, besteht.Material resistant in particular to alkaline melts Addition to patent 858376 The subject of patent 858 3 , 7 6 is a furnace lining which is particularly resistant to alkaline melts and which is essentially composed of oxides of alkaline earths, such as magnesium oxide or calcium oxide, or mixtures of the same and a protective coating of alkaline earth titanate.

Bei der weiteren Bearbeitung dieses Gebietes wurde nun gefunden, daß ein Werkstoff, der aus den Oxyden der Erdalkalien und einem schützenden Überzug, im wesentlichen aus Erdalkalititanat, besteht, nicht nur hervorragend als Ofenfutter, das insbesondere gegen alkalische Schmelzen beständig ist, verwendbar ist, sondern sich auch zur Herstellung anderer Gerätschaften, wie Tiegel, Platten, Rohre, Ofenaussetzsteine u. dgl., vorzüglich eignet. Zur Herstellung der gewünschten Gerätschaften kann man in der Weise vorgehen, daß man die aus Erdalkali geformten Geräte im Schmelzfluß mit einer Titanverbindung überzieht. Wie schon im Hauptpatent beschrieben, eignet sich Alkalititanat hierzu. Man kann jedoch auch die Geräte zunächst mit einer Titanverbindung bei gewöhnlicher Temperätur überziehen, z. B. durch Eintauchen in Titantetrachlorid, wobei sich auf der Oberfläche des Geräts Titandioxyd in feinverteilter Form niederschlägt, und anschließend das Gerät bis zum Schmelzbeginn erhitzen: Natürlich kann man die Titanverbindung auch in wäßriger oder organischer, z. B. alkoholischer Lösung auf die zu überziehenden Gegenstände aufbringen.In further processing of this area it has now been found that a material made from alkaline earth oxides and a protective coating, essentially made of alkaline earth titanate, is not only excellent as an oven lining, which is particularly resistant to alkaline melts, can be used, but can also be used to manufacture other equipment, such as crucibles, plates, pipes, and furnace stones and the like, excellently suited. To produce the desired equipment you can proceed in such a way that one of the devices formed from alkaline earth in the melt flow coated with a titanium compound. As already described in the main patent, is suitable Alkalitanat this. However, one can also use the devices initially with a titanium compound at ordinary temperature overlay, e.g. B. by immersion in titanium tetrachloride, with titanium dioxide being finely divided on the surface of the device Form, and then heat the device until it begins to melt: Of course you can also use the titanium compound in aqueous or organic, e.g. B. more alcoholic Apply the solution to the objects to be coated.
