    Thorotrast is a suspension of radioactive thorium dioxide first produced in Germany in 1928 and used as a contrast agent until the 1950s. Its principal use was for cerebral angiography: 90% of the estimated 50,000100,000 patients treated received it for this purpose.

  • Fabrication of Thorium and Thorium Dioxide

    Fabrication of Thorium and Thorium Dioxide

    Thorium based nuclear fuel is of immense interest to India by virtue of the abundance of Thorium and relative shortage of Uranium. Thorium metal tubes were being cold drawn using copper as cladding to prevent die seizure. After cold drawing, the copper was removed by dissolution in nitric acid. Thorium does not dissolve being passivated by nitric acid.

    Raman spectroscopic investigations were carried out on proposed nuclear fuel thorium dioxide–uranium dioxide (ThO2–UO2) solid solutions and simulated fuels based on ThO2–UO2. Raman spectra of ThO2–UO2 solid solutions exhibited twomode behavior in the entire composition range. Variations in mode frequencies and relative intensities of Raman modes enabled estimation of composition ...

    Thorium As Nuclear Fuel: the good and the bad

    Thorium fuel is a bit harder to prepare. Thorium dioxide melts at 550 degrees higher temperatures than traditional Uranium dioxide, so very high temperatures are required to produce highquality solid fuel. Additionally, Th is quite inert, making it difficult to chemically process. This is irrelevant for fluidfueled reactors discussed below.
