Data for: Growth-microstructure relationship in MgO-MgAl2O4 eutectic fabricated by micro-pulling down method with MgAl2O4 seed crystals

Numerical results of the image analysis. Perpendicular cross-sections of directionally solidified MgO-MgAl2O4 eutectic were cut perpendicular to the growth direction and polished. Images, in the form of scannning electron microscopy micrographs were processed using ImageJ 1.52g.
