Samarium Hydr oxides

Samarium has only one stable oxidation state (-1-3) within the electrochemical window of water, but it forms several relatively stable compounds with oxygen and hydrogen, which differ in their degree of hydration and in their crystallographic structure. These compounds absorb atmospheric CO2. Nominal degree of hydration indicated by a chemical name/formula reported in the literature does not necessarily reflect the actual degree of hydration. PZCs/IEPs of SiUjO, (nominally) are presented in Tables 3.743 and 3.744. 

Solid-to-liquid ratio (0.1 % by volume) was below standard level used in electroacoustic measurements (Chapter 2).
