<p>A soluble thermally cellulated, ceramic mold member, having gas evolved cells dispersed in a soluble crystalline matrix, the matrix consisting predominantly of at least one crystal phase selected from the group consisting of borates and phosphates of alkali metals, of divalent metals and of aluminum, and boron phosphate, and having at least one solubilizing agent selected from alkali metal compounds, divalent metal compounds and charred acrylic resin. A mixture capable of being thermally foamed to a cellulated body, the mixture consisting essentially of at least one phosphorous-containing compound, at least one boron-containing compound, at least one solubilizing agent selected from the group consisting of alkali metal compounds, divalent metal compounds and acrylic resins, at least one organic binder and a gas-evolving agent.</p> |
