What is it about?
This work focuses on the use of laser heating to control the crystallization process in eutectic composition glasses, specifically the Li2SiO3–CaSiO3 system. The study investigates how varying the scanning speed of the laser affects the microstructure of the resulting glass-ceramics. The authors aim to demonstrate that the crystallization behavior follows a relationship similar to the Jackson–Hunt model, which describes the average spacing between solid phases during solidification. The findings highlight the potential of laser technology to create materials with tailored properties for applications in optics, electronics, and other fields.
