Beschreibung
Zusammenfassung:	Composition for making casting moulds and cores consists of finely divided yttrium oxide, an acid, an inert organic solvent and a supplementary refractory product chosen from yttrium oxide, zirconium oxide, molten yttrium oxide, molten zirconium oxide, molten stabilised zirconium oxide, and a molten homogeneous mixture of yttrium and zirconium oxides. L'invention est relative à des revêtements de moules qui sont relativement non réactifs avec le titane ou les alliages de titane au cours de la coulée et sont préparés à base de bouillies d'yttria contenant éventuellement d'autres matériaux réfractaires, un acide et un solvant organique inerte.
