Description

Chemisch widerstandsfähiges Glas Gegenstand der Erfindung ist ein Glas von hoher Widerstandsfähigkeit gegen chemische Einwirkungen von Säuren und Alkalien, das insbesondere für chemische Gerätschaften, metallüberzogene Gläser, Glasfasern oder aus solchen hergestellte Erzeugnisse und für andere Zwecke geeignet ist, bei welchen eine hohe Resistenz gegen chemische Einwirkungen von größerer Bedeutung ist als die Durchsichtigkeit des Materials.Chemically resistant glass The subject of the invention is a Glass of high resistance to the chemical effects of acids and Alkalis, which are used in particular for chemical equipment, metal-coated glasses, Glass fibers or products made from them and suitable for other purposes is where a high resistance to chemical influences is of greater importance is than the transparency of the material.

Dieses Glas enthält erfindungsgemäß 2 bis 2o °/o Mangandioxyd (Mn02). Es setzt sich im übrigen aus Bestandteilen zusammen, zu denen ein zur Aufrechterhaltung des höheren Oxydationsgrades des Mangandioxyds geeigneter Stoff gehört.According to the invention, this glass contains 2 to 20% manganese dioxide (MnO2). In addition, it is composed of components to which one is used to maintain The higher degree of oxidation of manganese dioxide belongs to a suitable substance.

Um einem Glas von sonst üblicher Zusammensetzung die aufgezeigten erfinderischen Eigenschaften zuteil werden zu lassen, ist dem Glassatz Mangandioxyd in einem Gewichtsverhältnis von 2 bis 2o °/o einzuverleiben. Dabei ist es von Wichtigkeit, daß das Mangan in der genannten Oxydationsstufe erhalten bleibt, was auf verschiedene Weise; insbesondere durch Aufnahme von Bestandteilen, wie z. B. einer kleinen Menge (bis zu 2 Gewichtsprozent) von Chromioxyd (Cr203) oder einer hierfür geeigneten Menge von Natriumnitrat in den Glassatz möglich ist. Gläser im Sinne der Erfindung können beispielsweise folgende Zusammensetzungen aufweisen: i. Si0........ etwa 65,o Gewichtsprozent Ca0 ....... - o,65 - M90 ...... - 0,35 - Zn0....... - i,o - A1203...... - 3,0 - B203....... - 6,o Na20 ...... - 13,0 - Mn02...... - io,o - Cr203...... - I,0 - 2; Si02........ etwa 55. Gewichtsprozent- Ca0 ....... - 3 - - Mg0 ...... - 2 - A1203...... - 2 - B203....... - 6 - Na20 ...... - 12 - MnO, ...... - 18 - Cr203...... - 2 - In order to give a glass of otherwise customary composition the inventive properties shown, manganese dioxide is to be incorporated into the glassware in a weight ratio of 2 to 20%. It is important that the manganese is retained in the oxidation stage mentioned, which is done in various ways; in particular by the inclusion of components such. B. a small amount (up to 2 percent by weight) of chromium dioxide (Cr203) or a suitable amount of sodium nitrate in the glassware is possible. Glasses within the meaning of the invention can, for example have the following compositions: i. Si0 ........ about 65.0 percent by weight Ca0 ....... - o.65 - M90 ...... - 0.35 - Zn0 ....... - i, o - A1203 ...... - 3.0 - B203 ....... - 6, o Na20 ...... - 13.0 - Mn02 ...... - io, o - Cr203 ...... - I, 0 - 2; Si02 ........ about 55. Ca0 ....... - 3 - - Mg0 ...... - 2 - A1203 ...... - 2 - B203 ....... - 6 - Na20 ...... - 12 - MnO, ...... - 18 - Cr203 ...... - 2 -
