Phenomenology of corundum crystal formation in supercritical water fluid
This paper describes a solid phase transformation of aluminium hydroxide into oxyhydroxide (boehmite), and then into well formed fine crystals of corundum (*a-Al2O3) in the medium of a supercritical water fluid at a temperature of 450'C and a pressure of 30 MPa. Using electron microscopy the de...

| Zusammenfassung: | This paper describes a solid phase transformation of aluminium hydroxide into oxyhydroxide (boehmite), and then into well formed fine crystals of corundum (*a-Al2O3) in the medium of a supercritical water fluid at a temperature of 450'C and a pressure of 30 MPa. Using electron microscopy the development and processing of corundum crystal formation from incipient crystals to crystal growth and their perfecting is traced. |
