Development and Evaluation of the Optical Properties of Optical Glass Produced from Otamiri Silica Sand

ABSTRACT This work investigates the optical properties of glass prepared using Otamiri Silica sand mixed with analytical grade oxides as a function of their composition. Three batches were prepared with Phosphorus as the main variable of the SiO2-Na2OB2O3-CaO-ZnO glass system. The glass was melted in a ceramic crucible with a lid and the glasses melted after two hours of firing in a monolithic charcoal furnace. The effect of varying SiO2 and P2O5 on optical properties was determined using a S...

Mechanical and Microstructural Analysis of Equal Channel Angular Pressing of Almg3 Alloy with Additional 30o Twist Angle

ABSTRACT Equal channel angular pressing (ECAP) has over the years been used as a severe plastic deformation method to refine the grains and improve the strength of various metals. Even though this has been largely successful, research over the years has tried to increase the amount of strain induced in the materials used during this process so as to further increase the strength. In this research, an additional 30o twist angle was incorporated into the outlet channel of one of the ECAP dies u...

Synthesis and Characterization of Tin Iv Oxide (Sno2) Nanoparticles for Energy Applications

ABSTRACT Electrochemical capacitors (ECs) or Super capacitors (SCs) are energy saving devices which have excellent properties that include high power density, long cycle life, low temperature sensitivity and low maintenance cost. However, these devices have lower energy densities than conventional batteries. To improve on its energy density, SnO2 which is a metal oxide was considered as an electrode material because of its chemical inertness and thermal stability. SnO2 nanoparticles were synt...

The Effect Of Particle Size And Particle Size Distribution On The Modulus Of Rupture Of Some Nigerian Clays

ABSTRACT  The  effects  of  particle  size  and  particle  size  distributions  of  three clay samples, on their modulus of rupture were studied. The three clay samples were collected from natural clay deposits  at  Nsu;  Ohiya-  Umuahia;  and  Awo-Omamma  all  in south  eastern  Nigeria.  The  particle  size  analysis  of  the  clay samples was done...
