Use of Kazakhstan Nonferrous Metallurgical Slags for the Production of Slag Glass-Ceramics,

Abstract

Glass-ceramics were prepared from slag melts during crystallization at 700-1500C. It was shown that glass-ceramics crystallized at 700-800C had a uniform fine-grained structure and high glass content (30-40%) and those crystallized at 800-900C often had a non-uniform grain structure. Increase in crystallization temperature to 950-1050C favored the formation of uniform structure with a minimum amount of glass (10-15%). The native elements (S, Mn, Cu, Zn) present in the slag acted as crystallization centers and promoted precipitation of the 1st crystal phase and its stabilization.
