Radiochemical diagnostics of thermal hydrolysis of aluminum trichloride

“…In our work we used crystalline In the first series, a porcelain boat with a 4 35-mm bed (bed weight m 1 = 1.5 g) of labeled AlCl 3 crystals was placed in a closed chamber with a water vapor pressure of 1.5 + 0.5 kPa. Then, the boat with the crystals was transferred into a tubular reactor heated to T = 473 K, which was purged with air at partial water vapor pressure p = 1.0 31.5 kPa [3]. The gaseous HCl liberated from the reactor was absorbed in a trap packed with solid alkali.…”

“…In the third series, an aliquot of tritium water was placed in a Petri dish over which (in a closed volume) a boat with AlCl 3 containing no 36 Cl was kept for 4 h. Then, AlCl 3 was thermally hydrolyzed by the above procedure; the content of 3 …”

“…Therefore, detailed study of the process and, especially, of the mechanism of recently discovered [3,4] self-organization of microparticles of X-ray amorphous aluminum oxide in the course of gas-phase thermal hydrolysis is of particular importance. In the process, tubular particles (microtubes) of the composition Al 7 O 10 Cl .…”

A New Method for the Synthesis of Alumina Nanotubes from Polymer Composite Materials

“…In nanotube-based electronics, the importance of Al 2 O 3 nanotubes is increasing, for these tubes will be useful in the fabrication of catalyst, templates, and nanocapacitors . Several methods for preparing these Al 2 O 3 nanomaterials have been proposed, − e.g., using Al 4 O 4 C as a raw material, coating of CNTs with aluminum isopropoxide by the sol−gel method, electrochemical anodizing of Al films, and heating of partially hydrolyzed AlCl 3 powders . Generally, for the fabrication of nanomaterials based on the self-organization of metal-alkoxide-derived precursors, the syntheses are conducted in aqueous or nonaqueous solvents to disperse the reactants .…”
