Claim 1: Process for obtaining the CaO-based material, characterized in that it contains carbon nanotubes and comprises the following stages: a) solubilize between 0.005 and 0.05 g, preferably 0.005 g, of carbon nanotubes with 20.0 mL at 200 .0 mL of distilled water, preferably 20.0 mL; b) stirring for 15 to 20 minutes, preferably 20 minutes; c) add to the solution obtained in step "b", 10.00 to 50.00 g of calcium oxide; d) stirring for 10 to 15 minutes, preferably 15 minutes; e) transferring the compound obtained in step "d" to the ultrasound bath, for 25 to 30 minutes, preferably 30 minutes; f) transferring the compound obtained in step "e" to silicone molds containing hemispherical cavities of 6 to 8 mm. in diameter, preferably 8 mm. diameter; g) transferring the material obtained in "f" to the oven at a temperature of 60 to 80ºC, preferably 80ºC, for a time of 9 to 12 hours, preferably 12 hours for drying the material; h) demoulding the hemispherical granules obtained in step "g" and heating in an air atmosphere in a temperature range of 400 to 500ºC, preferably 500ºC, for a period of time of 20 to 30 minutes, preferably 30 minutes, then heating up to 700 to 800°C, preferably 800°C, for 20 to 30 minutes, preferably 30 minutes, thus removing carbon nanotubes; i) cooling the material obtained in step "h" to room temperature. |
