Inorganic dissolution promoter, amorphous high-concentration aqueous solution inorganic compound, solvent-free inorganic foam, noncombustible organic-inorganic foam, and heat-curable composition

摘要

The invention provides an inorganic dissolution accelerator used for obtaining a water-soluble inorganic compound(s), high in concentration and containing a large solid content, which accelerator is prepared by making one or more compounds selected from fluorides, mineral acids, mineral "ous" acids and salts thereof, and boric acid compounds, all either natural or synthetic, coexist with an alkali metal and/or substance containing an alkaline metal, and is able to transform metals and inorganic substances present in water, either natural or synthetic, containing as the main component silicon Si, aluminumAl, and/or boron B, into amorphous highly water-soluble inorganic compounds having the solubilities equal to, or larger than those well known in the art.
