Effect of Precursors on the Hydrothermal Synthesis of KAl(OH)_2CO_3 Powder
Source abstract
Abstract
KAl(OH)2CO3 powders with different morphology were synthesized by the hy-drothermal method using AlCl3·6H2O, Al(NO3)3·6H2O, Al2(SO4)3·12H2O as the precursors at 120℃ for 24h. The results show that Al(NO3)3·6H2O is the best precursor for the synthesis of KAl(OH)2CO3. The KAl(OH)2CO3 powder synthesized in the hydrothermal aqueous with NO3-concentration of 1.2mol/L possesses particle sizes of less than 20nm, slenderness ratio of less than 5 , and good size distribution.
