Description

Verfahren zur Herstellung feuerbeständiger Gegenstände aus Rutil. Die Erfindung betrifft ein Verfahren zur Herstellung von feuerbeständigen Gefäßen und Gegenständen aus Rutil, die gleichzeitig gegen chemische Mittel widerstandsfähig sind. Der kutil (Titanoxvd) ist ein natürliches Mineral, das man für die Zwecke der Erfindung sehr fein mahlen muß, worauf man der lufttrockenen Masse ohne Zusatz von Bindemitteln die gewünschte Form erteilt und den Formling schließlich bei hoher Temperatur brennt. Hierbei verändert die Masse ihre Farbe und geht allmählich von Hellbraun in Dunkelbraun und selbst Dunkelrot oder Purpur über und nimmt ein kristallinisches Gefüge an. Schon bei einer Temperatur von Soo° C besitzt der Formling eine erhebliche Festigkeit und Härte: die so hergestellten Gefäße sind feuerfest und säurebeständig. Bei Anwendung einer höheren Brenntemperatur überzieht sich die ganze Oberfläche mit einer Glasur.Process for the manufacture of fire-resistant articles from rutile. The invention relates to a method for producing fire-resistant vessels and objects made of rutile, which are also resistant to chemical agents are. The kutil (Titanoxvd) is a natural mineral that can be used for the purpose the invention must grind very finely, whereupon the air-dry mass without any additive of binders given the desired shape and finally the molding at high Temperature burns. Here the mass changes its color and gradually disappears Light brown in dark brown and even dark red or purple over and takes on a crystalline Structure on. Even at a temperature of Soo ° C, the molding has a considerable amount Strength and hardness: the vessels made in this way are fireproof and acid-resistant. When using a higher firing temperature, the entire surface is covered with a glaze.

Wenn man auch schon Zirkon und Rutil zur Herstellung feuerfester, als Ofenbaumaterial zu verwendender Steine vorgeschlagen hat, so war dennoch die Eigenschaft des lufttrockenen Rutils;=- für sich allein ohne jeden Zusatz feuerfeste Gegenstände zu geben, die regen chemische Einwirkungen beständig sind, nicht bekannt. In manchen Fällen ist es vorteilhaft, Mischungen von gröberen und feineren Teilen von Rutil für die Formmasse zu verwenden, weil anscheinend dadurch die Festigkeit und Feuerbeständigkeit erhöht wird.Even if zirconium and rutile are used to manufacture refractory, suggested stones to be used as furnace building material, so it was Property of air-dry rutile; = - refractory on its own without any addition It is not known to give objects that are resistant to chemical influences. In some cases it is advantageous to mix coarser and finer parts to use rutile for the molding compound, because apparently this increases the strength and fire resistance is increased.

Die Erfindung findet auch bei der Herstellung von Ziegeln und Auskleidungsmaterialien für in der Glasindustrie gebrauchte Ofen und Töpfe Anwendung. Ebenso ist die Erfindung für die 1Ietaliindustrie von großem Werte, wo gegen chemische Beeinflussungen widerstandsfähige Gefäße gebraucht werden.The invention also applies to the manufacture of bricks and lining materials for ovens and pots used in the glass industry. So is the invention of great value for the metal industry, where resistant to chemical influences Vessels are needed.
