Valorization of phosphogypsum waste through acid geopolymer technology: synthesis, characterization, and environmental assessment

2023, Journal of Alloys and CompoundsCitation Excerpt :Ferroelectric LiNbO3 crystal decomposes from 300 °C, which leads to a significant decrease in resistivity and limits its operating temperature to below 600 °C [6–9]. Non-ferroelectric α-quartz crystal and AlPO4 crystal undergo an α-β crystalline phase transition at 573 °C and 588 °C, respectively [7,10]. On the other hand, the GaPO4 crystal grown by the hydrothermal method is an excellent material for manufacturing high-temperature sensors.

2014, Journal of Crystal GrowthCitation Excerpt :In the case of crystal growth, C/S is greater than 1 and the solution is slightly supersaturated, whereas the C/S ratio is slightly less than 1 for the dissolution process [19]. This method was applied to grow AlPO4 [12] and GaPO4 [18,21] crystals in acidic H3PO4 and H2SO4 solutions and to develop a controlled etching process for generating surfaces without defects to obtain piezoelectric resonators with high quality factors Q [24,25]. Hydrothermal growth methods principally depend on the nature of the solvent and the growth temperature.

2012, Computational Materials ScienceCitation Excerpt :However, the low piezoelectricity and phase transition at 573 °C [8] limits its application. So, materials scientists developed other members of quartz family such as AlPO4, GaPO4, GeO2 and GaAsO4 [9–12], which have higher piezoelectricity and higher transition temperature than α-quartz. Interestingly, BaZnO2 possesses the same structural symmetry with α-quartz (space group P3121, point group 32) [13], and may be another promising new candidate in this family.
