Abstract:
A study has been made of the compounds formed in the system SrO-Al₂O₃-H₂O under varying conditions of temperature and pressure. The hydrates prepared included S. AHg and SAHn, both of which have been known for some time, and S.A.H. which was recently reported by other workers. Several new hydrates were prepared hydrothermally: SAH, SgAH and S.A.H. SAH and S.A.H. had been described previously as SyiH. and Sj-A. respectively. The compounds prepared were investigated by X-ray diffraction methods, optical microscopy, differential thermal analysis, thermograviroetric analysis, static thermal analysis, infra-red spectroscopy and density measurement. Single crystal X-ray methods were used to determine the space group, cell dimensions and cell contents cf the new compounds prepared. An attempt was made to determine the structure of SAH, as the structure of the isomorphous barium compound has been only partially solved. However, the available crystals were too small to give good intensity data. The structure of S"A, which is isomorphous with Cl whose structure hss long been a problem, was also studied. Again, poor intensity data prevented a complete solution. The inversion of SA at high temperatures to a structure resembling that of BA was studied, using differential thermal analysis and X-ray techniques. Finally, a comparison was made of the methods of preparation and structures of the aluminate hydrates of the three alkaline earths calcium, strontium and barium.
