Thallium(I) carbonate is the inorganic compound with the formula Tl2CO3. It is a white, water-soluble salt. It has no or very few commercial applications. It is produced by treatment of thallous hydroxide with CO2.[3]
Safety
Like other thallium compounds, it is 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.[4]
