The method of image analysis revealed how non-equilibrium solidification conditions (contact with air, with a mold, without contact) affect the macrostructural parameters of glass-crystalline spinel-pyroxene materials. It was revealed that nonequilibrium conditions determine the zoning of the structure. A mechanism has been formulated that determines the microzoning of the structure, which consists in the fact that in the process of crystallization a critical size of spinel arises, upon reaching which it acquires its own & # 171; zone of influence & # 187; - a certain volume of the melt, proportional to its size, which forms a shell around the spinel due to epitaxial growth
