MOLD MATERIAL MIXTURES CONTAINING METAL OXIDES OF ALUMINUM AND ZIRCONIUM IN PARTICULATE FORM |
摘要 |
The invention relates to mold material mixtures containing at least one aluminum oxide in the alpha phase and/or at least one aluminum/silicon mixed oxide, except for aluminum/silicon mixed oxides having a layered silicate structure, as a particulate metal oxide, in combination with refractory mold base materials and a water glass-based binder system. The mold material mixtures are used for the production of molds and cores for the foundry industry. |
