Thermal properties and crystallization kinetics of Er:LiY(PO.sub.3./sub.).sub.4./sub. glass
Rodová, Miroslava ; Cihlář, Antonín ; Král, Robert ; Sveshnikov, Alexey ; Nitsch, Karel
This contribution deals with study on thermal properties of phosphate glass with a nominal composition of Er:LiY(PO3)4 when searching new scintillation glasses.
Analysis of crystallization kinetics of Li-Y phosphate glass under non-isothermal conditions
Nitsch, Karel ; Rodová, Miroslava ; Sveshnikov, Alexey
Crystallization kinetics of erbium doped LiY(PO3)4 glass was studied experimentally using DSC under non-isothermal conditions. Based on the experimental data the applicability of Johnson-Mehl-Avrami model was tested for description of crystallization kinetics of above mentioned glass.
Preparation and thermal properties of glassy LiY(PO.sub.3./sub.).sub.4./sub..
Rodová, Miroslava ; Král, Robert ; Nitsch, Karel
Glass with composition of LiY(PO3)4 was prepared by quenching of molten mixture of lithium carbonate, yttrium phosphate and P2O5. Crystallization kinetics was experimentally studied using non-isothermal DSC and data obtained were evaluated by means of Johnson-Mehl-Avrami and Matusita models.
Glass formation conditions in supercooled molten zinc chloride
Rodová, Miroslava ; Kožíšek, Zdeněk ; Nitsch, Karel
Solidification of ZnCl2 melt was studied experimentally by methods of thermal analysis and theoretically by construction of TTT curves.
Studium strukturní relaxace cérem dopovaných sodno-gadolinitých skel pomocí TMA
Rodová, Miroslava ; Chromčíková, M. ; Nitsch, Karel ; Liška, M.
Structural relaxation of Ce-doped Na-Gd phosphate glasses was studied experimentally using TMA under non-isothermal conditions and the process was described by Tool-Narayanaswamy-Mazurin model.
Crystallization study of Na-Gd phosphate glasses by non-isothermal DTA
Nitsch, Karel ; Kožíšek, Zdeněk ; Rodová, Miroslava
Crystallization kinetics of glass with nominal composition of Ce:NaGd(PO.sub.3./sub.).sub.4./sub. were studied using non-isothermal DTA in order to study its thermal stability.
Růst a charakterizace krystalů Pb(Cl,Br).sub.2./sub
Rodová, Miroslava ; Cihlář, Antonín ; Nitsch, Karel ; Polák, Karel ; Sedmidubský, D.
Lead chloride (PbCl.sub.2./sub.)and bromide (PbBr.sub.2./sub.) single crystals are materials with excellent acousto-optical and luminescent properties. The similar properties can be expected from the crystals prepared from Pb(Cl,Br).sub.2./sub. system
Elektrická vodivost přechlazených tavenin halogenidových solí
Sveshnikov, Alexey ; Demo, Pavel ; Kožíšek, Zdeněk ; Nitsch, Karel ; Rodová, Miroslava
One of the long standing open problems of materials science and technology is how to produce a macroscopic crystal of required physical and chemical properties under a limited number of conditions adjustable and controlable from the outside. For example, purity of a starting material or temperature imposed on the freezing system may play the role of such controlling parameters
