Description

Verfahren zur Herstellung titanoxydhaltiger Massen für keramische Zwecke Bei der Herstellung von keramischen elektrischen Isolierkörpern aus Titandioxyd wird das im Handel befindliche, fein gemahlene Titanweiß mit Zusätzen versehen, welche für die Erzielung eines elektrisch und keramisch hochwertigen Scherbens notwendig sind. Solche Zusätze können z. B. sein: Magnesiumoxyd, Calciumoxyd, Zirkonoxyd usw.Process for the production of titanium oxide-containing compounds for ceramic Purposes In the manufacture of ceramic electrical insulating bodies made of titanium dioxide the finely ground titanium white available on the market is provided with additives, which is necessary for the achievement of an electrically and ceramic high quality body are. Such additives can, for. B. be: magnesium oxide, calcium oxide, zirconium oxide etc.

Titanweiß hat aber infolge seiner Kornfeinheit eine große Brennschwindung von 2o bis 25%. Um diese zu verringern, ist bisher ein Teil dieses Titandioxyds bei Temperaturen von i2oo bis 140o° vorgebrannt und nochmals gemahlen worden; denn eine; gute Reaktion hängt sehr von der Kornfeinheit der Oxydkomponenten ab. Da der Feinmahlung im keramischen Betrieb aus wirtschaftlichen Gründen Grenzen gesetzt sind und eine Verwendung von Hydroxyden oder eine gemeinsame Ausfällung der Hydroxyde im Arbeitsprozeß einer keramischen Fabrik schwer durchführbar ist, so wird das Mischgut im keramischen Brand erst bei verhältnismäßig hohen Temperaturen reagieren.However, due to its fineness, titanium white has a large firing shrinkage from 2o to 25%. In order to reduce this, part of this has been titanium dioxide pre-fired at temperatures from 120 to 140o ° and ground again; because one; good reaction depends very much on the grain size of the oxide components. Since the Fine grinding in ceramic operations is limited for economic reasons are and a use of hydroxides or a coprecipitation of the hydroxides is difficult to carry out in the work process of a ceramic factory, so the mix only react in ceramic firing at relatively high temperatures.

Gemäß der Erfindung werden unter Vereinfachung des Arbeitsverfahrens die Aufbereitungskosten herabgesetzt sowie bessere Reaktionsbedingungen der Mischungen erzielt, wenn die Zusätze schon während des Herstellungsverfahrens des Titanweißes eingeführt werden und nicht erst bei der Aufbereitung des Versatzes in der keramischen Fabrik.According to the invention, while simplifying the working procedure the processing costs are reduced and the reaction conditions of the mixtures are improved achieved if the additives are used during the manufacturing process of the titanium white are introduced and not only during the preparation of the offset in the ceramic Factory.

Zu diesem Zweck wird eine Titansulfatlösung oder ausgefällte Metatitansäure mit dem oxydischen oder oxydbildenden Zuschlagstoff, z. B. mit Zirkonsulfat oder mit Zirkonoxyd, vermischt, um gemeinsam mit der Metatitansäure in den Calcinierofen zu gelangen. Dort wird das Gut bei einer Temperatur, die dem Zuschlagstoff angepaßt is@i entwässert. Die sonst für die Titanweißfarberr notwendige Feinstmahlung unterbleibt. Das Erzeugnis ist sehr gut durchgemischt und kann unmittelbar nach dem Verlassen des Calcinierofens keramisch aufbereitet und geformt werden. Der Zusatz von notwendigen Plastifizierungsmitteln, z. B. von rohem Ton, erfolgt nach dem Calcinieren.A titanium sulfate solution or precipitated metatitanic acid is used for this purpose with the oxidic or oxide-forming aggregate, e.g. B. with zirconium sulfate or with zirconium oxide, mixed together with the metatitanic acid in the calcining furnace to get. There the material is at a temperature that is adapted to the aggregate is @ i dehydrated. The fine grinding otherwise necessary for the titanium white color is omitted. The product is very well mixed and can be used immediately after leaving of the calcining furnace can be ceramically prepared and shaped. The addition of necessary Plasticizers, e.g. B. of raw clay, takes place after calcining.

Es ist bekannt, bei der Herstellung von Titanweiß für Farbzwecke sog. Kompositions-oder Mischpigmente mit anderen Oxyden, wie Zirkonoxyd, seltenen Erden, Zinkoxyd, Bariumsulfat oder Calciumsulfat, in der geschilderten Weise zu erzeugen. Diese Verbindungen dienen ausschließlich Anstrichzwecken und werden infolgedessen nach dem Verlassen des Calcinierofens sehr fein gemahlen.It is known in the production of titanium white for color purposes so-called. Composition or mixed pigments with other oxides, such as zirconium oxide, rare earths, Zinc oxide, barium sulfate or calcium sulfate, in the one described way to create. These compounds are and are used for painting purposes only as a result, it is very finely ground after leaving the calcining furnace.

Das hier beschriebene Verfahren unterscheidet sich in seiner Aufgabenstellung und Zielsetzung von der Farbenherstellung auf der Basis von Titanweiß, ferner auch durch den Verzicht auf Farbwirkung und durch die Verwendung des Drehofenproduktes ohne Feinstvermahlung.The procedure described here differs in terms of its task and the aim of producing paints on the basis of titanium white, as well by renouncing the color effect and by using the rotary kiln product without fine grinding.
