Preparation method for aluminum-magnesium spinel
The invention discloses a preparation method for aluminum-magnesium spinel. The method comprises the following steps of 1 mixing, wherein reaction raw materials are prepared and mixed evenly to obtain mixed raw materials; 2 charging and sealing, wherein the mixed raw materials are charged in a crucible, and the crucible is sealed; 3 sintering, the sealed crucible is placed in a high-temperature furnace to be roasted to obtain blocky products; 4 crushing and screening, wherein the blocky products are crushed and screened to obtain final products. According to the preparation method for the aluminum-magnesium spinel, the preparation temperature of the aluminum-magnesium spinel can be significantly lowered, the raw material source is convenient to obtain, the using amount of additives is little, the product purity is high, the preparation technology is simple, the energy consumption is little, the preparation cost is low, and the method is suitable for refractory materials of metallurgical production.
