Titanium dioxide (TiO2) has a very high melting point and boiling point. Here's a breakdown:

* Melting Point: 1843 °C (3349 °F)

* Boiling Point: 2972 °C (5382 °F)

Important Note: These are the values for pure TiO2. The melting and boiling points can be slightly different depending on the specific crystal structure of TiO2 (rutile, anatase, or brookite) and any impurities present.
