ABSTRACT:
A process for producing a water glass-based material and the inorganic material itself is disclosed. The process involves providing an amount of water glass and causing a solid content of the water glass to react with a coagulant. The reaction is created in one of three possible general ways. Firstly, the water glass and coagulant can be reacted by heating the mixture to a temperature in the range of 80.degree. C. to 600.degree. C. Secondary, the water glass and coagulant can be reacted by providing an alkaline substance in combination with them. Thirdly, the water glass and coagulant can be reacted by providing the coagulant in the form of porous particles which include polyvalent ions capable of coagulating the water glass. All three methods of reacting the coagulant and water glass can include one or more heating steps. The material produced is particularly resistant to heat, water and the combination of heat and water. The material provides a strong adhesive and can be utilized to shape molded objects since it remains in a moldable state for a long period of time after the components are mixed together.
