Claims38
A rigid inorganic foam product consisting essentially of prills of foam of one or more layer minerals, each prill being of cellular structure.
A rigid inorganic foam of cellular structure consisting essentially of a mixture of layer minerals.
A rigid inorganic foam of cellular structure consisting essentially of montmorillonite.
A rigid inorganic foam of cellular structure consisting essentially of sepiolite.
A rigid inorganic foam of cellular structure consisting essentially of a ball clay and/or a fire clay.
Rigid inorganic foam prills having a cellular structure and consisting essentially of one or more layer minerals.
A suspension of two or more layer minerals in an aqueous solution of a surface active agent.
A suspension of one or more layer minerals selected from kaolinite, or a kaolin-containing clay, montmorilloite and sepiolite in an aqueous solution of a surface active agent, wherein the surface active agent is one capable of forming a stable foam from the layer mineral(s).
A dry powder comprising two or more layer minerals and a surface active agent.
A dry powder comprising kaolinite or a kaolin-containing clay, montmorillonite or sepiolite and a surface active agent.
