About the crystallization of the Hornblende in titanium-containing slags; a correction
Abstract
The presence of hornblende in slags is of great interest to mineralogists, petrologists and metallurgists. In the studied titaniferous slags, either no mineral is found that is similar to the previously described basaltic hornblende or is not amphibole at all, or it turns out that the mineral identified in the first study as basaltic hornblende is actually olivine, a member of the series of isomorphic compounds Mg₂SiO₄ — Fe₂SiO₄ (maybe with admixtures of some other orthosilicate molecules). This shows that all the assumptions that were made above when accepting the presence of amphibole in slags as a fact are incorrect: these titaniferous slags are more refractory and more viscous than the hypothetical slag with basaltic hornblende. With this article I would like to show the importance of the issue of the possibility of crystallization of amphiboles in slags and the need for special careful studies of crystalline formations in slags that are more or less similar to amphibole. It seems that in order to accurately establish the possibility of crystallization of minerals of this group in factory slags, those crystalline precipitates that are identified as amphibole must be examined with X‑rays.
