Abstract
The present invention relates to a method for manufacturing a ceramic foam and the ceramic foam thus obtained, using raw material obtained from mining tailings, a fluxing agent, and glycerol as the sole foaming agent.
Claims16
A method for making ceramic foams, CHARACTERIZED in that it comprises the stages of:
- providing a raw material coming from mining tailings, wherein said raw material includes SiO2 in a proportion of at least or about 70% m/m, and Fe2O3 in a proportion of less than or about 10% m/m;
- mixing said raw material with a fluxing agent and glycerol as the sole foaming agent until a homogeneous mixture is obtained;
- sintering the homogeneous mixture obtained;
- and
- cooling the homogeneous mixture to obtain the ceramic foam.
