ABSTRACT:
Lamellar-structured highly microporous silicate compositions are provided which can be used as insulative articles and insulation material. The silicate is in the form of lamellae selected from the group consisting of mica and vermiculite. The silicate lamellae form the microporous structure, by forming the pore walls with the lamellae. Processes are described which prepare these compositions by removing the water from flocculated or unflocculated aqueous dispersions of chemically delaminated silicates while the arrangement of the lamellae in the dispersion is largely preserved, resulting in the highly microporous lamellar structure.
