Potassium Cerium Selenates

Anhydrous KCe(Se04)2 forms by dehydration of the hexahydrate at 220°C, G6mez Madrazo et al. [4], or of the tetrahydrate at 63 to 130°C, Giolito, lonashiro [6]. The pycnometrically determined density is 4.02 g/cm at 25°C [4]. For behavior on further heating, see below. 

The dihydrate forms by heating the hexahydrate at 100°C. Its pycnometrically determined density is 3.60 g/cm at 25°C, Gomez Madrazo et al. [4].
