Die Erfindung betrifft optische Gläser nach dem Patent 936 472.The invention relates to optical glasses according to patent 936,472.
In der Patentschrift 936 472 sind optische Gläser beschrieben, die zu mindestens 20 Gewichtsprozent aus Metaphosphaten der Erdalkalimetalle und zu mindest 9 Gewichtsprozent aus mindestens einem Oxyd eines zwei- bzw. dreiwertigen Elements und/oder einem OrthQphosphat der Erdalkalimetalle bestehen. Die Beispiele dieser Patentschrift zeigen Gläser, die durchweg neben Magnesiummetaphosphat und teilweise Borsäure als Glasbildner Orthophosphate der Erdalkalimetalle aufweisen.In the patent specification 936 472 optical glasses are described that at least 20 percent by weight Metaphosphates of the alkaline earth metals and at least 9 percent by weight of at least one oxide bivalent or trivalent element and / or an orthophosphate of the alkaline earth metals. the Examples of this patent show glasses that consistently in addition to magnesium metaphosphate and partially Boric acid have orthophosphates of the alkaline earth metals as glass former.
Es wurde nun gefunden, daß besonders widerstandsfähige Gläser zu erschmelzen sind, wenn die Gläser zu 35 bis 50 Gewichtsprozent aus einem Erdalkalimetaphosphat, zu 15 bis 40 Gewichtsprozent aus einem Erdalkalioxyd, zu 4 bis 20 Gewichtsprozent aus mindestens einem Oxyd der Elemente Zink und Cadmium, zu 4 bis 14 Gewichtsprozent aus Borsäure und zu 2 bis 25 Gewichtsprozent aus mindestens einem der folgenden Bestandteile bestehen:It has now been found that particularly resistant glasses are to be melted when the 35 to 50 percent by weight glasses made of an alkaline earth metaphosphate, 15 to 40 percent by weight of an alkaline earth oxide, 4 to 20 percent by weight at least one oxide of the elements zinc and cadmium, up to 4 to 14 percent by weight from boric acid and 2 to 25 percent by weight consist of at least one of the following components:
Aluminiumoxyd,Aluminum oxide,
Lanthanoxyd,Lanthanum oxide,
Zirkonoxyd,Zirconium oxide,
Titan dioxyd,Titanium dioxide,
Bleioxyd,Lead oxide,
Aluminiumorthophosphat,Aluminum orthophosphate,
Natriumorthophosphat undSodium orthophosphate and
Kaliumorthophosphat.Potassium orthophosphate.
Die Anteile an Aluminium- und Lanthanoxyd sollen dabei 12 Gewichtsprozent, die an Zirkonoxyd 5 Gewichtsprozent, die an Titandioxyd 1,5 Gewichtsprozent, die an Bleioxyd 10 Gewichtsprozent und die der genannten Orthophosphate 5 Gewichtsprozent nicht überschreiten.The proportions of aluminum and lanthanum oxide should be 12 percent by weight, that of zirconium oxide 5 percent by weight, that of titanium dioxide 1.5 percent by weight, that of lead oxide 10 percent by weight and the of the orthophosphates mentioned do not exceed 5 percent by weight.
Gläser aus den genannten Bestandteilen weisen sehr gute optische Werte auf, die zum Teil bereits aus den Katalogen der Glasherstellerfirmen bekannt sind.Glasses made from the components mentioned have very good optical values, some of which are already derived from the Catalogs of the glass manufacturing companies are known.

Gegenüber diesen bekannten Gläsern weisen sie jedoch eine wesentlich verbesserte Widerstandsfähigkeit gegenüber Säuren und Atmosphärilien auf. Das macht sich besonders günstig bei der Verarbeitung dieser Gläser bemerkbar, da der Ausschuß erheblich geringer wird. Es ist dabei zu bemerken, daß die Schäden, die bei der Bearbeitung an den bekannten Gläsern entstehen, im allgemeinen erst nach der Feinpolitur der Gläser festzustellen sind.Compared to these known glasses, however, they have a significantly improved resistance to acids and atmospheres. This is particularly beneficial when processing them Glasses noticeable because the rejects are considerably less. It should be noted that the damage caused arise when working on the known glasses, generally only after the fine polishing of the Glasses are to be determined.
Den Gläsern nach der Erfindung können in üblicher Weise geringe Anteile zur Stabilisierung, beispielsweise Kieselsäure, und zur Entfärbung, beispielsweise Arsentrioxyd, zugesetzt werden. Sie lassen sich ohne Schwierigkeiten nach den üblichen Methoden der Glasherstellung erschmelzen, abgießen und kühlen. Die geeignetsten Temperaturen sind leicht durch Probenahmen festzustellen.The glasses according to the invention can usually contain small amounts for stabilization, for example Silicic acid, and for decolorization, for example arsenic trioxide, are added. You can do without Difficulties melting, pouring and cooling according to the usual methods of glass production. the The most suitable temperatures can easily be determined by taking samples.
In den nachfolgenden Tabellen ist eine Anzahl derartiger Gläser angegeben, und zwar zeigt die Tabelle 1 Gläser, die aus Calciummetaphosphat, Borsäure, Bariumoxyd, Zinkoxyd und Zirkonoxyd sowie zum Teil ferner aus Lanthanoxyd und Aluminiumoxyd bestehen. Die optische Lage dieser Gläser entspricht der der niedrigbrechenden Lanthankrongläser.A number of such glasses is given in the following tables, namely Table 1 shows Glasses made from calcium metaphosphate, boric acid, barium oxide, zinc oxide and zirconium oxide as well as for Part also consist of lanthanum oxide and aluminum oxide. The optical position of these glasses corresponds to of the low-refractive lanthanum crown glasses.
