ABSTRACT:
Preformed silica shapes such as pins and spouts useful in the casting of molten aluminum are provided by which a high strength chemical bond is developed by adding 2 to 10 wt. % of an alkali phosphate-modified alumino-silicate binder to a fused silica mix. To this silica and binder mix, sufficient water is added to obtain a castable consistency. Then, a shape is cast, dried, and shipped for service.
