In an alternative embodiment, a heavy metal fluoride glass composition range (in mol percent) comprises (16-30)BaF2.(8-26)Hf F4.(6-24) of (0-24)InF3, (0-24)GaF3 and (0-19)AlF3.(1-16)CdF2.(6-24)YbF3.(4-26)ZnF2. A preferredheavy metal fluoride glass produced in accordance with the present invention comprises a composition (in mol %) and comprises about 26BaF2.18Hf F4.7InF3.5GaF3.10CdF2.18YbF3.16ZnF2. A preferred heavy metal fluoride glass has maximum thickness of most preferably about 3 mm. Another preferredheavy metal fluoride glass comprises a composition (in mol %) and comprises about 26BaF2.18Hf F4.12AlF3.10CdF2.18YbF3.16ZnF2.

Ultra optical glasses are proposed for attaining noble glazes of high reflection and shine. In addition, these glasses can be used as semi-mirrors and optical instruments. In this reseach attempts were devoted mainly to introduce a glass system with the highest possible refractive index in which the highest reflection is desirable. Thus different amounts of heavy metal oxides modifiers, such as...

Industrial activities and high traffic density are the most important heavy metal pollution sources in urban areas. Roadside dust created by atmospheric deposition can be one of the best indicators for heavy metal contamination levels. The present study reports the spatial distribution patterns and degree of heavy metal pollution (Cd, Cr, Ni, Pb, Zn, and As) in 50 roadside dust samples from urb...
متن کاملDesigning heavy metal oxide glasses with threshold properties from network rigidity.
Here, we show that a new class of glasses composed of heavy metal oxides involving transition metals (V2O5-TeO2) can surprisingly be designed from very basic tools using topology and rigidity of their underlying molecular networks. When investigated as a function of composition, such glasses display abrupt changes in network packing and enthalpy of relaxation at Tg, underscoring presence of fle...
