The LiPO3-RbPO3 system was investigated by differential thermal analysis, X-ray diffraction and infrared spectroscopy. The system forms two linear polyphosphate compounds: Li2Rb(PO3)3 and LiRb(PO3)2. The first one melts in a peritectic reaction at 552°C and the second one melts congruently at 613°C. It is established that both compounds are mixed polyphosphates with chain structure. Their reticular distances and IR characteristics are given here.
