ABSTRACT:
A thermal insulating material of an expanded, shell-less silica-hydrate has a small bubble structure to enhance the thermal insulating characteristics of the material. Also described is a process for the production of the expanded, shell-less silica-hydrate through selective heating of the silica-hydrate in a moist environment.
