Abstract

The mechanism of eliminating platinum inclusions in laser glass by POCl₃ gas bubbling is discussed from the thermodynamic aspect in the preset paper. It is deduced from calculated reaction free energy that platinum inclusion is ionized after POCl₃ gas bubbling in the existence of water and oxygen. After reaction platinum inclusion is dissolved as platinum (II) metaphosphate in the laser glass matrix.
