A process for producing fused alumina-zirconia grits includes mixing raw materials suitable to produce grits with the following chemical composition, in % by weight: ZrO₂+HfO₂: 10-60%, Al₂O₃: 38-90%, SiO₂: 0.8%, and Impurities: 1.2%. The process also includes adding carbon and aluminum metal to the mixture of raw materials to obtain a charged batch containing, in % by weight,: Carbon: 0.4-1% Aluminum metal: 0.5-2.5%. The process further includes melting the charged batch in an electric arc furnace with a voltage of 175-205 V and a delivered specific electrical energy of 2.5 to 4 kWh per kg of charge.
