Abstract

In this work was studied the partial substitution in the design of a refractory mix of the fine crystalline graphite for prefabricate nanoparticles of the seam source of graphite, improving the refractory properties of the material, getting a better resistant to the chemical attack by the slag and steel liquid metal. The raw materials and nanoparticles of crystalline graphite were characterized by X-ray diffraction (XRD), Sherrer equation, and scanning electron microscopy (SEM). The nanoparticles size determines the crystalline of the graphite used in the mixes obtained after different steps of mechanic milling. The nanoparticles of materials were added to the mixes in different proportions. The commercial raw materials used for this investigation were: commercial silicon carbide high purity (97% SiC), calcined bauxite (85% Al2O3), alpha calcined alumina, and crystalline graphite (94% C). Additionally, six different sizes of graphite nanoparticles were selected. The particle size of the initial commercial graphite was 0.044mm and the final nanoparticles obtained in this investigation by mechanic milling was 18 nm. The measurement of the particle size of the nanoparticles was made by the Scherrer equation, XRD and SEM.
