Thallium(I) carbonate (Tl2CO3) is a chemical compound. It can be used for the manufacture of imitation diamonds, in chemical analysis to test for carbon disulfide, and as a fungicide. Like other thallium compounds, it is considered extremely toxic, with an oral median lethal dose of 21 mg/kg in mice. Due to its toxicity, it is listed in the United States List of Extremely Hazardous Substances as of 2007.[2]
Safety
Conditions/substances to avoid are: acids, magnesium with hydride, aluminium, hydrosulfuric acid, phosphorus pentoxide.
Preparation
Thallium carbonate is created by the saturation of hot aqueous thallium(I) hydroxide with carbon dioxide.
