Abstract
Methods of forming by polymerization reaction a silicate gel which exhibits intumescence upon application of heat and various products formed from the resulting ceramic foam materials. Specific formulations and processing steps best suited to particular applications are set forth, together with examples of various types and configurations of the resulting products. These include structural materials, such as sheets of wall board, very low density insulation materials, articles useful as a protective barrier from heat or flame, vitreous materials useful as heat resistant tiles or as abrasive wheels or blocks for grinding or polishing, and ceramic foam materials incorporating silica gel and processed solely with microwave heat.
