👉 Piezocrystallization is a process in which a material, such as quartz or silicon carbide, undergoes a transformation from an amorphous state to a crystalline state. This transformation occurs due to a phenomenon called phase change, where the atomic structure of the material changes while it remains at room temperature. In piezocrystallization, the material is exposed to high pressure and temperature (e.g., 20-50 MPa and 180°C
