Boron Removal from Metallurgical-Grade Silicon by Slag
To enhance the removal of B from metallurgical-grade Si (MG-Si) by the CaO-SiO2-CaCl2 slag refining technique, Ar gas was injected during the refining process. The effects of the refining time, Ar gas flow rate, and the blowing-pipe immersion depth on the removal of B from MG-Si were studied. The results show that the injection of Ar gas To contact a faculty, please view our faculties page or call the University's main switchboard on 020 8417 9000.

September The formation of a boron-rich layer (BRL) is a common phenomenon during the fabrication of boron (B) emitter due to different solubility of B in the silicon oxide layer and the silicon substrate. In our work, we employ alumina oxide (Al 2O 3) layers as reaction barriers to avoid the production of the silicon oxide layer and eliminate the BRL.Promotion of boron diffusion and gettering by

Development of a boron-free filler metal for brazing nickel
A new material for boron-free brazing of nickel-based superalloys is described that utilizes a transient liquid-phase bonding (TLPB) mechanism. Commercially available AMS 4764 powder (52.8Cu–37.5Mn–9.7Ni) was mixed with pure Ni powder to increase Ni content in the filler metal. This alloy is a good candidate for TLPB in Ni Geothermal fluids consist of hot water, steam and gases in water-dominated reservoirs. They contain various dissolved major elements such as sodium, potassium, calcium, silica, bicarbonate, carbonate, chlorine, sulphate and minor elements such as boron, fluorine, lithium, iron, arsenic, mercury and bromine at different concentrations in Prediction of geothermal originated boron contamination by
