Abstract

The high-temperature (950-1050°C) crystallization behavior of x-ray amorphous Al2O3 and its reaction with lithium carbonate in the range 500-700°C were studied using Al2O3 samples prepared by five different procedures: thermal decomposition of Al(NO 3)3·9H2O, Al2(C 2O4)3·nH2O, aluminum hydroxides synthesized via Al3+ precipitation from aluminum nitrate and aluminum chloride solutions by a 20% excess of a concentrated NH 4OH solution, and sol-gel-prepared aluminum hydroxide. The results demonstrate that the preparation procedure has a significant effect on the crystallization behavior and solid-state reactivity of x-ray amorphous aluminum oxide.
