چکیده

A series of borotellurite glass system doped with copper oxide was synthesized using the method melt quenching. The density decreases whereas its molar volume increases in respect to concentration. amorphous nature prepared glasses proven utilisation XRD spectra. Meanwhile, samples' elastic properties are determined from measurement longitudinal and shear velocities ultrasonic technique. modulus, bulk modulus Young's has shown an irregular trend that fluctuates within certain limits. Moreover, FLUKA Monte Carlo code is implemented determine shielding features at gamma energy 0.3565, 0.6616, 0.8348 1.3325 MeV. Linear attenuation coefficients acquired XCOM found be good agreement relative difference <1%. sample B2O3TeO2CuO1 (with highest percentage TeO2) best material this study.

Luminescence Properties of Oxyfluoride Glass and Glass Ceramic Doped with Y3 + Ions

 Oxyfluoride glass ceramics containing CaF2nano-crystals doped with Y3+ ions were prepared by one-step crystallization of SiO2- Al2O3- CaO- CaF2 glasses at different temperatures. X- ray diffraction (XRD) results have revealed that CaF2 was the only precipitated crystalline phase in glass ceramic samples. According to the XRD results, a glass ceramic was selected as the best sample in order to ...

Microstructure, mechanical and thermal properties of chalcogenide glasses and glass-ceramics based on Se-As-Ge system nucleated by Sn

In particular, chalcogenide glasses and glass-ceramics are new materials that exhibit good transparency in infrared region (0.8-12µm). We can overcome the main weakness of these glasses by improving the hardness through controlling crystallization. In this paper, we report results of a study on chalcogenide glasses in the ternary system of As-Se-Ge with nominal composition of Snx (Se...

THE COMPARISON OF MECHANICAL PROPERTIES OF SINTERED ?. QUARTZ SOLID SOLUTION AND GAHNITE GLASS – CERAMICS IN ZNO-AL2O3-SIO2 SYSTEM

The effect of precipitation of ?.qss. and gahnite phases during heat treatment of glass frits in the ZnO-Al2O3-SiO2 system on the mechanical property of resulting glass-ceramic specimens were investigated. It was shown that gahnite glass-ceramics had higher bend strength and toughness values than ?.qss. ones. The results are attributed to the higher modulus of elasticity as well as higher therm...

Simulation of Hydrogenated Boron Nitride Nanotube’s Mechanical Properties for Radiation Shielding Applications

Radiation shielding is an obstacle in long duration space exploration. Boron Nitride Nanotubes (BNNTs) have attracted attention as an additive to radiation shielding material due to B’s large neutron capture cross section. The B has an effective neutron capture cross section suitable for low energy neutrons ranging from 10 to 10 eV and hydrogen is effective at slowing down high energy neutrons....
