The Latest Issue Of "Glass And Ceramics" For 2014
Has published the 8th issue of a monthly research journal "Glass and Ceramics" for 2014. Contents of the August issue:
Yellow up-conversion luminescence of transparent glass-ceramics with erbium ions
synthesized transparent glass ceramics containing nanocrystals of lead fluoride β-PbF2 with erbium ions Er3 + (average diameter of 8.5 nm) by a secondary source of heat treatment oxyfluoride glass system SiO2 - GeO2 - PbO - PbF2, doped Er2O3. Investigate its thermal and structural properties, optical absorption and up-conversion luminescence. The resulting glass-ceramics as a promising phosphor produces an intense yellow glow when excited in the infrared range of the spectrum.
Interaction with fiberglass cement stone
The results of investigations of processes of interaction fiberglass used to disperse the reinforcement of concrete with cement stone. It has been established that the interaction is dependent upon the chemical composition of the fiber cement composition and hardening condition. It is shown that for steamed better to use concrete instead of basalt fiber fine powder basaltic glass. In this case, the compressive strength of the cement stone can be increased to 2 times.
