Here we demonstrate progress on electrodeposition of photoactive silicon films from an environmentally friendly molten CaCl2 electrolyte, which is the first step of a new route to a practical low-cost silicon solar cell. We report electrodeposition of severalmicron thick silicon films on a graphite substrate in a bath of molten CaCl2 containing SiO2 nanoparticles. The best silicon deposits was ...

The oxidation of a carbon anode with air and CO2 occurs during the electrolysis of alumina in Hall-Héroult cells, resulting in a significant overconsumption of carbon and dusting. Boron is well known to decrease the rate of this reaction for graphite. In this work, the application of boron oxide has been investigated to evaluate its inhibition effect on the air oxidation reaction, and to provid...

This Investigation studies the Mechanical and Tribological behaviour [ i.e dry sliding behaviour] of Al matrix composites reinforced with SiC and Gr particulate up to 10%, to study the effect of reinforcement, Load, Sliding speed and Sliding distance on stir cast Al-SiC and Al-Gr Metal matrix composites. Parametric studies indicate that the hardness, tensile strength of Al-SiC composite is grea...

The calcined petroleum cokes are used in production of aluminum anode-grade, graphite electrode, needle-grade, titanium dioxide pigments. Petroleum coke (green and calcined) is produced by the high pressure thermal decomposition of heavy petroleum process streams and residues. Green coke undergoes additional thermal processing to produce calcined coke. Various properties of calcined cokes from ...
