An attempt has been made to eliminate easily reducible oxide components, such as SiO 2 , TiO 2 , alkaline oxides and Fe 2 O 3 and thereby exclude oxygen sources from casting fluxes. The new casting fluxes are based on CaO, Al 2 O 3 , MgO, SrO with limited amounts of alkaline and alkaline earth fluorides. Melting behaviour, viscosity, Al 2 O 3 solubility and wear of submerged nozzles is essentially the same as that of conventional casting fluxes. The new fluxes also tend to undergo glassy solidification.
