Cubic crystals

Abstract

In this article I present, however possible, a complete list of crystals of the cubic system obtained to date. Here we are really dealing with a number of substances that are exceptional in their properties, like exceptional forms of the cubic system among all the others. When the list is compiled, this exclusivity is in the chemical composition of the substances What is striking is the possibility of dividing them into those few headings that form the basis of my presentation. Other features of the chemical composition of substances in this series will be discussed at the end of the article. I needed to compile this list simply because from those described, I could single out those crystals that cannot be determined by the method of crystal chemical analysis.
