Abstract

The equilibrium solubility of nitrogen in aluminosilicate melts, similar in composition to many blast furnace slags, has been measured, although the silica contents under investigation have been limited by experimental problems to between 30 and 38 mole pct. The solubility is a chemical rather than a physical phenomenon, it being necessary to impose severe reducing conditions to obtain significant quantities of nitrogen in solution. The dependence of solubility on slag basicity has been investigated, and a simple dependence upon nitrogen and carbon monoxide contents in the gas phase established. From the results, it is postulated that an exchange reaction takes place between nitrogen gas and bridging oxygen atoms in the aluminosilicate structure, and the results are discussed in relation to the structure of the melts.
