In this study, the Li<SUP>+</SUP> ion emission characteristics of β-eucryptite were investigated. The β-eucryptite Li<SUP>+</SUP> ion source does not exhibit outgassing in an ultra-high vacuum system, even at a high filament temperature, and the purity of the emitted Li<SUP>+</SUP> ion beam is very high. The emitted current densities functions are in good agreement with the Richardson equation and Child-Langmuir model. The energy for Li<SUP>+</SUP> ion to be extracted from a solid to a vacuum was measured to be 1.1 eV. This value means that Li<SUP>+</SUP> ion can be easily extracted from solid to vacuum, i.e., β-eucryptite is a good Li<SUP>+</SUP> ion source. Finally, this study suggests a half-life time and ion current equation as a function of source temperature, source potential, and working time. The suggested equations can be used widely in various fields, including in the design and construction of a Li<SUP>+</SUP> ion source (ion gun), especially for an ion scattering spectroscopy study.
