Thallium(I) carbonate is the inorganic compound with the formula Tl₂ CO₃. It is a white, water-soluble solid. It has no or very few commercial applications. It is produced by treatment of thallous hydroxide with CO₂.[2]

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.[3]

gollark: I'm surprised.

gollark: Why not just reverse-engineer and patch the installer‽

gollark: nvidia bad. That is all.

gollark: Well, on Linux, their drivers work perfectly.

gollark: Well, the name for the laser network was *originally* THOR, and I had to go to a LOT of effort to make the acronym work, but that array was destroyed when some iteration of CN went down.
