Abstract
Abstract There are disclosed gels composed of hydrated phyllosilicates combined with a lattice expanding agent selected from the group consisting of a primary aminocarboxy acid, lysine orotate, and glycylglycine. Both organic and inorganic additions, as well as ion exchange products, are disclosed. The gels, with or without the additions, may be polymerized and may be formed or shaped. Also disclosed are methods for generating the gels and for treating the gels generated.
