Abstract Ammonia hydrates are important components in planetary interiors, among which ammonia hemihydrate (AHH) exhibits remarkable stability under high pressure. In this study, we report for the first time the elastic properties of the recently discovered quasibcc ammonia hemihydrate (AHH-$q$bcc) at high pressures, using externally heated diamond anvil cells combined with Raman spectroscopy and Brillouin scattering. We synthesized single crystals of AHH-$q$bcc in the diamond anvil cell (DAC). Subsequently, we measured its full elastic tensor up to 17.6 GPa at room temperature via Brillouin scattering. The results show that the elastic constants increase linearly with increasing pressure. Based on the obtained elastic constants, we calculated the bulk modulus, shear modulus, Poisson's ratio, and velocity anisotropy. The results reveal significant anisotropy in wave velocities and Poisson's ratio on the (110) crystallographic plane of AHH-$q$bcc. Compared to ice VII, AHH-$q$bcc has a lower bulk modulus and shear modulus, yet exhibits a higher compressional wave velocity and a similar shear wave velocity. Our findings provide important constraints for understanding the internal structure and seismic velocity profiles of icy planets.

Online attention
Altmetric calculates a score based on the online attention an article receives. Each coloured thread in the circle represents a different type of online attention. The number in the centre is the Altmetric score. Social media and mainstream news media are the main sources that calculate the score. Reference managers such as Mendeley are also tracked but do not contribute to the score. Older articles often score higher because they have had more time to get noticed. To account for this, Altmetric has included the context data for other articles of a similar age.
