| Popis: | The mechanism of synthesis of yttrium-aluminum garnet Y3Al5O12 (YAG) from a mixture of yttrium and ammonium carbonates NH4Y(CO3)2∙H2O with aluminum and ammonium hydroxycarbonates NH4AlCO3(OH)2 is shown to be different from the mechanism of synthesis from a mixture of hydrated yttrium and aluminum oxides. Calcination of a mixture of hydrated oxides leads to the formation of both Y3Al5O12 (YAG) and the impurity phases Y4Al2O9 and YAlO3, whereas monophase YAG is formed after a mixture of carbonates undergoes calcination. The difference in the mechanism of YAG synthesis is probably due to the difference in particle sizes formed after carbonates and hydrated oxides undergo calcination. |
