A method for obtaining a composite material based on basalt with a copper filler by spark plasma sintering has been developed. It was found that the sample sintered at 1080 °C and a pressure of 3,8 kN has a crystalline structure with a uniform distribution of copper, high density and reflectivity, which makes it promising for artistic applications. In contrast, the sample obtained at 1300 °C without pressure has an amorphous structure and increased porosity. The research results have prospects for the application of this material in the artistic field, including the creation of mosaics, decorative panels, as well as use in jewelry.
