Use of Hydrogen for the Production of Materials with Regulated Porosity

We investigate structural features of new porous materials (gasars) produced with the use of hydrogen. We show that the dimension of the pores and their number and form can be controlled through technological parameters. We note that both ordered and disordered structures are formed in gasars. An ordered structure formed due to gas-eutectic crystallization is called a gasarite. We found bubble and dendritic gasarites and analyzed structural features and conditions of their formation. We selected large, medium, fine, and ultrafine pores in gasarites of various kinds. Structural specific features of gas-eutectic materials enable one to predict their properties and determine conditions of production.
