Abstract
Artificial Ullmanite NiSbS. A compound corresponding in chemical composition to the mineral ulmanite was obtained by Prof. N. S. Kurnakov and Art. J. Posternak (at the St. Petersburg Polytechnic Institute) and transferred to the Mineralogical Institute of the Mining Institute for crystallographic research. CoSbS compound. This compound was obtained (as well as NiSbS) by stud. I. Posternak, was given to me by Prof. N. S. Kurnakov. The walls of the voids in the alloy were dotted with irregularly arranged, thin-plate-like crystals with a strong metallic luster of steel-gray color.
