What is Thallium(III) Oxide Like?
Thallium(III) oxide looks like a white powder. It is quite heavy for its size. This compound is also very dangerous and should be handled with extreme care. It is a semiconductor, which means it can conduct electricity under certain conditions, but not as easily as a metal. When it mixes with acids, it forms other thallium compounds that are also harmful. You won't see it dissolve if you put it in water.
How is Thallium(III) Oxide Made?
Scientists can make thallium(III) oxide by a process called oxidation. This involves adding oxygen to another compound called thallium(I) oxide. It's like how rust forms on iron when it reacts with oxygen in the air.
What is Thallium(III) Oxide Used For?
One possible use for thallium(III) oxide is in solar cells. These are devices that turn sunlight into electricity. Scientists are always looking for new materials to make solar cells more efficient.
