Investigating laser sintering in Y3Al5O12 ceramics

This study investigates the experimental parameters of the laser sintering process of Y3Al5O12 ceramics. Ceramic powders were produced using the polymeric precursor method and sintered using a CO2 laser as the heating source. The samples were characterized using differential thermal analysis, thermogravimetric analysis, X-ray diffraction, and scanning electron microscopy techniques. The results showed that parameters such as powder calcination temperature, dwell time, and laser power density rate are crucial in obtaining dense ceramic bodies. Furthermore, developing and using a sample holder made of the same material composition to be sintered showed significant advances in the laser sintering process.
