Crystallization of barium disilicate glass at high pressure

Glasses that undergo the high-pressure crystallization process can present different phases after sample recovery, in the same way that high-pressure crystalline phases can present several phase transitions, depending on the pressure levels applied. To date, studies that address the in situ crystallization of glasses are scarce, and the characterization of the structure formed in situ and its transformations during decompression are being studied. This work aims to address this gap by employing the Multi Anvil system in conjunction with in situ analysis of the formed structure and sample recovery to investigate the phases retained at atmospheric pressure. Furthermore, we will seek to further analyze the mechanical properties. The results should provide information about the processes involved in high pressure, helping to understand the formation and control of the structures formed. As well as identifying reversible and irreversible processes.
