ABSTRACT:
A foamed ceramic product and method for making same is disclosed. The foamed ceramic is characterized by a high compressive strength, high insulating properties and low fluid permeability when compared against conventional materials. This foamed ceramic is made by mixing a clay mineral with a foaming agent comprising a combination of sulfate and sulfide compounds, heating to a temperature of about 1,000.degree. C. where controlled foaming occurs and then cooling the resulting foamed product.
Additionally, there is disclosed a foamed ceramic product and method for making same which is characterized by its fire resistant properties as a result of creating micro cracks therein which permit controlled fluid permeability. This foamed ceramic product is made by controlling the phase constituents and heating and cooling temperatures to induce stresses which result in such micro cracks.
