What Is The Boiling Point Of Na2O?

Sodium oxide (Na2O) is an ionic compound that does not have a boiling point. Ionic compounds do not exist as discrete molecules, but rather as a crystal lattice held together by strong electrostatic forces between positively and negatively charged ions. When heated, these compounds undergo a process called sublimation, in which they transition directly from a solid to a gas phase without passing through a liquid phase. Therefore, it is not appropriate to assign a boiling point to Na2O.
