Beschreibung
Zusammenfassung:	This invention relates to the manufacture of silica-containing bonding materials capable of imparting improved green-body strength to ceramic articles such as refractory bodies which are to be subsequently sintered and to composite bodies made from such materials as asbestos, fiber glass, sawdust, and wood shavings. More specifically, this invention is founded primarily upon the discovery that when certain organic compounds and/or MgO treated in a particular manner are added to true solutions, colloidal solutions, or suspensions of silicates containing at least 1 mole of silica per liter in solution and/or colloidal solution and having a pH greater than about 10, a reaction will occur reducing the pH and polymerizing the silica. The resulting silica network structure bonds very strongly to inert or essentially inert filler materials, forming bodies having uniquely desirable characteristics.
