Fluorophosphate glasses of the composition 5Ba (PO3) 2- (38-x) AlF3-57RF2-xNdF3 were obtained, where R = Ba, Ca, Sr, Mg, Pb; x = 0.5, 3, 5 mol%. It was found that the introduction of lead fluoride reduces the glass transition and crystallization temperatures. It has been shown that for all systems containing MgF2, the formation of a uovite phase is characteristic. The UV-cutoff has shifted from 200 nm to 250 nm.
