Abstract (en)
[origin: EP1215293A1] Process for the iron-free melting and/or storing of liquid magnesium and magnesium alloys comprises adhering sintered alumina plates to the inner wall of indirectly heated steel crucibles. Preferred Features: The plates have a thickness of 2-20, preferably 3-10 mm. The adhesive is a ceramic composition containing 85% Al2O3, 14.5% MgO and 0.5% SiO2, together with soda water glass in a ratio of 1: 1-6, preferably 4: 1. Zirconium-containing alloys can be produced.
