Thermal behavior of metallic aluminum in a Container glass melt

Abstract

The thermal behavior o f metallic aluminum was studied in the temperature ränge of 1100 to 1500°C in a Container glass melt. The dissolution of the metal was determined as a function of aluminum input, glass volume, melting time and the type of glass used. By analogy, melts containing magnesium cuttings were also investigated. With the aid of electron microscopy, it was possible to establish a reaction scheme of Oxidation and reduction processes. Only 2 to 3 % of the aluminum introduced causes the formation of silicon spheres. The main part will be oxidized through reactions with oxygen, hydroxide and polyvalent ions in the melt.
