Abstract
Thermal treatment of alpha -Si sub 3 N sub 4 , Nd sub 2 O sub 3 , and SiO sub 2 up to 1450 degrees C results in oxidation of Si sub 3 N sub 4 and formation of SiO sub 2 . The latter reacts with Nd sub 2 O sub 3 , leading to the formation of Nd polysilicates with different compositions. The activation energy of oxidation is determined.
