The only compound of antimony with hydrogen that is known with certainty is the gaseous antimony trihydride, or stibine, SbH 3. A solid substance, described as di-antimony dihydride, Sb 2 H 2, is stated to have been obtained by various electrolytic methods and by the reduction of antimony compounds by nascent hydrogen.
The global supply of antimony is dominated by one country which has led the European Union to classify antimony as a critical raw material. Other than the rare-earth elements antimony has the highest supply risk. Therefore, a feasibility study on the recycling of antimony and antimony compounds is of great importance. This research focuses on two types of antimony containing wastes: (1) metal ...

Antimony is chalcophile, occurring with sulfur and the heavy metals, lead, copper, and silver. Over a hundred minerals of antimony are found in nature. Stibnite (Sb 2 S 3) is the predominant ore mineral of antimony. The most important use of antimony metal is as a hardener in lead for storage batteries.
Thallium (I) The thallium(I) halides are stable. In keeping with the large size of the Tl + cation, the chloride and bromide have the caesium chloride structure, while the fluoride and iodide have distorted sodium chloride structures. Like the analogous silver compounds, TlCl, TlBr, and TlI are photosensitive.
