Description

Anwendung von Alkaliborat beider Zusammensetzung glasiger Stoffe. Zur Zusammensetzung -glasiger Stoffe, z. B. Glasuren, Emaillen, optische Gläser u. dgl., benutzt man Borax Na2B,07 1oH20 und zusammen mit diesem öder an dessen Stelle Borsäure H3 B 0,s als Flußmittel. In beiden Fällen wird eine verhältnismäßig große Menge von Kristallwasser eingeführt, dessen Entfernung nicht unerhebliche Mengen von Brennstoff kostet.Use of alkali borate in the composition of glassy substances. For the composition - glassy substances, e.g. B. glazes, enamels, optical glasses and the like, one uses Borax Na2B, 07 1oH20 and together with this or in its place boric acid H3 B0, s as a flux. In both cases, a relatively large amount of crystal water is introduced, the removal of which costs not inconsiderable amounts of fuel.

Gemäß der vorliegenden Erfindung wird-nun der Borax bzw. die Borsäure ersetzt durch ein Alkalipentaborat, und man kann dann mit Mengen auskommen, die erheblich weniger Kristallwasser enthalten.According to the present invention, the borax or boric acid is now used replaced by an alkali pentaborate, and you can then get by with quantities that contain considerably less water of crystallization.

Beispielsweise kann eine boraxhaltige Ofenglasur zusammengesetzt sein wie folgt 16,o kg Borax, 2,o - Soda, 5,o - Borsäure, 20,0 - Quarz, 74,0 - Mennige. Diese Bestandteile enthalten 9,8 kg Kristallwasser. Verwendet man \ atriumpentaborat von der Formel Na=Blo0,r roH=O, so ergibt sich zweckmäßig folgende Zusammensetzung: 14,6 kg Pentaborat, 3,8 - Soda, 20,o - Quarz, 74,0 - Mennige. Die eingeführte Kristallwassermenge beträgt 4,4 kg. Eine boraxhaltige Stengutglasur kann zusammengesetzt sein wie folgt 83,4 kg Feldspat, 12,5 - Kaolin, . 6o,o - Sand, 9,8 - Bariumkarbonat, 76,4 - Borax, 8,4 - Magnesia, =z4.,2 - Mennige. Die eingeführte Kristallwassermenge beträgt 36,o kg.For example, an oven glaze containing borax can be composed as follows 16.00 kg of borax, 2, o - soda, 5, o - boric acid, 20.0 - quartz, 74.0 - red lead. These components contain 9.8 kg of crystal water. If \ atrium pentaborate of the formula Na = Blo0, r roH = O is used, the following composition is expediently obtained: 14.6 kg pentaborate, 3.8 - soda, 20, o - quartz, 74.0 - red lead. The amount of water of crystallization introduced is 4.4 kg. A stencil glaze containing borax can be composed as follows 83.4 kg feldspar, 12.5 - kaolin,. 6o, o - sand, 9.8 - barium carbonate, 76.4 - borax, 8.4 - magnesia, = z4., 2 - red lead. The amount of water of crystallization introduced is 36.00 kg.

Bei Pentaboratanwendung ergibt sich folgende Zusammensetzung: 47,6 kg Pentaborat, 13,2 - Soda, 12,5 - Kaolin, 9,8 - Bariumkarbonat, 8,4 - Magnesia, 119,2 - Mennige. Die eingeführte Kristallwassermenge beträgt 144 kg.The following composition results when using pentaborate: 47.6 kg pentaborate, 13.2 - soda, 12.5 - kaolin, 9.8 - barium carbonate, 8.4 - magnesia, 119.2 - red lead. The amount of water of crystallization introduced is 144 kg.

Das Natriumpentaborat kann technisch in der in den Patenten 344222 und 356824 beschriebenen «'eise dargestellt werden. Dabei werden fein zerkleinerte Borerze unter Wasserzusatz in bekannter «'eise mit Kohlendioxvd oder Schwefeldioxyd bis zur Sättigung behandelt, und die erhaltenen Lösungen werden nach dem Filtrieren auskristallisiert.The sodium pentaborate can technically be found in the patent No. 344222 and 356824 can be shown. Finely chopped up Borer ores with the addition of water in the well-known manner with carbon dioxide or sulfur dioxide Treated to saturation, and the solutions obtained are after filtration crystallized out.
