Not to be confused with thermionic emission.
Thermal ionization, also known as surface ionization or contact ionization, is a physical process whereby the atoms are desorbed from a hot surface, and in the process are ionized.
Thermal ionization is used to make simple ion sources, for mass spectrometry and for generating ion beams.[1] Thermal ionization has seen extensive use in determining atomic weights, in addition to being used in many geological/nuclear applications.[2]
