Abstract
Data presented in metal-hydrogen phase diagrams are summarized for metals that normally do not form hydrides. At high temperatures, all systems of this sort are characterized by a gas-eutectic equilibrium. The gas-cutectic transformation is analyzed in detail. It is shown that this transformation generates various gas-solid structures. Porous materials produced as a result of gas-eutectic reactions have numerous advantages over traditional materials. We call this family of new porous materials gasars.
