To obtain large transparent ceramic samples, we optimized the drying step process using COMSOL Multiphysics®. Indeed, green body's drying in a climate chamber is the critical step when large size and complex shape samples are needed. Then we obtained 75 mm diameter and 10 mm thickness highly transparent spinel ceramics.
