Abstract

Die Erfindung betrifft eine Formstoffmischung für Gießereizwecke, bestehend aus Formsand, Natronlauge, Binder auf Alkali-Silikat-Basis und Zuschlägen, wobei die Formsandpartikel eine Korngröße von 0,1 - 1 mm aufweisen. Die Formstoffmischung enthält 0,1 - 10 Gewichts% Natronlauge bezogen auf das Sandgewicht und 0,1 - 5% Binder auf Alkali-Silikat-Basis mit einem Feststoffanteil von 20 - 70%, wobei die Natronlauge eine Konzentration von 20 bis 40 Gewichts% aufweist und wobei das Formstoffgemisch als Zuschlag 0,1 - 3 Gewichts% einer Suspension mit einem Feststoffanteil zwischen 30 - 70% an amorphem, kugelförmigem SiO2 enthält. Das amorphe, kugelförmige SiO2 ist in zwei Korngrößenklassierungen in der Suspension enthalten mit einer ersten Korngrößenklassierung A, beinhaltend SiO2 -Partikel mit einer Korngröße zwischen 1 - 5 Mikrometern und einer zweiten Korngrößenklassierung B, beinhaltend SiO2 -Partikel mit einer Korngröße zwischen 0,01 - 0,05 Mikrometern. Für die Volumenanteile der beiden Korngrößenbereiche A, B gilt folgende Verteilungsregel: 0,8 zu 1,0 bis 1,2 zu 1. Weiterhin betrifft die Erfindung einen Formling für Gießereizwecke sowie ein Verfahren zur Herstellung des Formlings.
