This invention relates generally to oil and gas industry, more particularly, to production of proppant, the ceramic granulated propping agents used for hydro fracturing treatment of carbonaceous formations aimed to stimulation of oil and gas production from wells. This invention provides the structure of a proppant including two components, wherein one of components comprises one or several phases belonging to the AI<SUB>2</SUB>O<SUB>3</SUB> - B<SUB>2</SUB>O<SUB>3</SUB> system: chemical compounds, solid solutions, eutectic mixtures; the second phase comprises one or several phases belonging to AI<SUB>2</SUB>O<SUB>3</SUB> - B<SUB>2</SUB>O<SUB>3</SUB> - SiO2 system: triple and quadruple chemical compounds, solid solutions, and eutectic mixtures; a proppant comprising one or several phases of several possible and belonging to AI<SUB>2</SUB>O<SUB>3</SUB> - B<SUB>2</SUB>O<SUB>3</SUB> system: chemical compounds, solid solutions, eutectic mixtures; a proppant comprising one or several phases of several possible and belonging to AI<SUB>2</SUB>O<SUB>3</SUB> - B<SUB>2</SUB>O<SUB>3</SUB> - SiO<SUB>2</SUB> system: triple and quadruple chemical compounds, solid solutions, and eutectic mixtures. This invention provides the method of proppant production including the separate or joint grinding and mixing of aluminum-bearing and boron-bearing initial components, granulation by dry or wet method, drying and firing with formation of one or several phases in the classes of chemical compounds, solid solutions, and eutectic mixtures, which composition belongs to AI<SUB>2</SUB>O<SUB>3</SUB> - B<SUB>2</SUB>O<SUB>3</SUB> system, and a also triple and quadruple chemical compounds, solid solutions, and eutectic mixtures belonging to AI<SUB>2</SUB>O<SUB>3</SUB> - B<SUB>2</SUB>O<SUB>3</SUB> - SiO2 system, wherein the proppant firing is carried out at the temperature of 200 - 1550 °C.
