The extraction of hydrogen from white and high-silicon cast iron (Si∼14%) at 1000°, 1250° and 1650°C has been studied. The extracted hydrogen was separated from other gases by the aid of a palladium tube: this apparatus is capable of measuring both the evolution rate and total volume of hydrogen. Hydrogen diffused rapidly through the palladium tube at 800°, and most of the methane decomposed into carbon and hydrogen, the latter being able to diffuse through the tube. The diffusion rate of CO and N2 were negligible. It is showen that the vacuum heating technique at 1000°C can be applied to the determination of hydrogen in white and high-silicon cast iron. Addition of small amount of titanium (1.37%) or tellurium (0.3%) had no effect on the results.
