verwendete Tonerde und Tonerdesalze, treten, ebenso wie in den nach den Verfahren der genannten Patentschriften bereiteten Massen, quantitativ derart zurück, dass durch sie die massgebenden Eigenschaften des Zements, insbesondere die durchscheinende Beschaffenheit, nicht erzeugt werden. Dasselbe gilt von dem Verfahren des deutschen Patentes Nr. 162671, nach welchem zur Herstellung eines als Kittmittel verwendbaren Zements Phosphorsäuro oder deren saure Salze mit durch sie zerlegbare oder mit ihnen reagierende Berylium-

ist es aber gerade die in überwiegender Menge vorhandene Tonerde bzw. die Tonerdesalze, welche die durchscheinende Beschaffenheit des Zements bedingen.
Dieses Ergebnis wird stets erhalten, wenn man Aluminiumphosphat oder-borat für sich oder mit Tonerdehydrat gemischt in solchen Mengen mit einer Lösung von Phosphorsäuren mischt, dass eine plastische, zu einem steinharten Zement erhärtende Masse entsteht.

EMI2.1
The alumina and alumina salts used, as in the masses prepared according to the processes of the patents mentioned, recede quantitatively in such a way that they do not produce the decisive properties of the cement, in particular the translucent nature. The same applies to the process of German Patent No. 162671, according to which phosphoric acid or its acidic salts with beryllium, which can be decomposed by them or react with them, are used to produce a cement that can be used as a cement.
EMI2.2
But it is precisely the alumina or alumina salts that are present in the predominant quantity that determine the translucent nature of the cement.
This result is always obtained when aluminum phosphate or borate is mixed with a solution of phosphoric acids, either by itself or mixed with alumina hydrate, in such quantities that a plastic mass that hardens to a rock-hard cement is produced.
