The simultaneous electrodeposition of lead and lead dioxide
The simultaneous electrodeposition of both Pb and PbO2 from Pb(NO3)2 solutions onto a Ni substrate has been investigated with particular reference to the influence of different organic addition agents on the nature of the Pb and PbO2 deposit, the porosity of the Pb deposit and the current …

The oxidation kinetics of liquid lead and lead alloys
"Liquid lead and lead-silver alloys were investigated to determine the rates and products of oxidation in pure oxygen at temperatures of 350 to 600°C. The kinetic data were determined using a Cahn electro-balance. Liquid lead was found to follow a cubic rate of oxidation between 350 and 400°C. A …

Lead silicate solubility and the control of lead contamination in drinking water
The intake of lead into the human body has become an area of major concern because high levels of lead are harmful and can cause physiological damage, especially in children. It has been suggested that adding NaSiO₃might control Pb²⁺ contamination of drinking water supplies (c.g., Thresh 1922). …
