    Non-colloidal thorium (thorium nitrate) injected in rats concentrated in a non-soluble form in bone marrow macrophages, hepatocytes and Kupffer cells. These deposits of thorium associated with phosphorus can be explained by the formation of thorium phosphate in lysosomes that remain in tissue for a long time.

    Thorium | Article about thorium by The Free Dictionary

    Th0 2 is obtained by the thermal decomposition of thorium nitrate, thorium oxalate, or thorium hydroxide. Above 200°C, thorium reacts with hydrogen to form powdery hydrides having such compositions as ThH 2 and ThH 3. At 700°–800°C in a vacuum, all bound hydrogen may be removed from thorium. When thorium is heated in nitrogen …

    The solutions of pure thorium nitrate, free from potassium nitrate, were made up of known molality, and the concen- tration of thorium nitrate was determined by analysis. Conductivity measurements were made with a Philips conductivity bridge. The readings were corrected by subtracting the blank value obtained under the same conditions but …
