cze	Studium draselno-zinečnatých borofosfátových skel	Byla připravena a studována skla v kompozičních řadách K2O-(50-x)ZnO-10B2O3-40P2O5 a xK2O-(50-x)ZnO-20B2O3-30P2O5 (x =0, 10, 20, 30, 40 a 50 mol% K2O). Při záměně draslíku za zinek klesá měrná hmotnost, teplota skelné transformace a chemická odolnost skel, zatímco jejich molární objem roste. Strukturní změny byly studovány pomocí 11B a 31P MAS NMR a Ramanovy spektroskopie.
eng	Study of Potassium-Zinc Borophosphate Glasses	Potassium-zinc borophosphate glasses were prepared and studied in two compositional series xK2O-(50-x)ZnO-10B2O-40P2O5 and xK2O-(50-x)ZnO-20B2O3?30P2O5 with x =0, 10, 20, 30, 40 and 50 mol% K2O. The replacement of zinc by potassium decreases the density and increases the molar volume of these glasses, whereas glass transition temperature and chemical durability decrease with increasing potassium content. Structural changes were studied by 11B and 31P MAS NMR and Raman spectroscopy.	Glasses; Raman spectroscopy; Nuclear magnetic resonance
