摘要 |
The casting-mold material designed to manufacture casting molds used in casting high melting-point substances. The casting mold formed from a powder component containing magnesium oxide and aluminum oxide and a liquid component. The powder component additionally contains a calcium aluminate and an alkali fluoride or an earth alkali fluoride and the liquid component contains a polyelectrolyte and a basic component, the latter determining the liquid component pH value between 10 and 14.
