Radioactive characterization of the main materials involved in the titanium dioxide production process and their environmental radiological impact

Posted on by admin

Abstract A study about the distribution of several radionuclides from the uranium and the thorium series radionuclides along the production process of a typical NORM industry devoted to the production of titanium dioxide has been performed. With this end the activity concentrations in raw materials, final product, co-products, and wastes of the production process have Read more about Radioactive characterization of the main materials involved in the titanium dioxide production process and their environmental radiological impact[…]

Thermal characterization of new fire-insulating materials from industrial inorganic TiO2 wastes

Posted on by admin

Abstract Two wastes, red gypsum (RG) and unattacked ilmenite (known as tionite), from the titanium dioxide production industry have been used to study the possibility of manufacturing new fire-isolating materials, and for that they were characterized for mineralogical composition and thermal behavior. Tests have demonstrated that these wastes could be used for fire insulation. Thermogravimetry Read more about Thermal characterization of new fire-insulating materials from industrial inorganic TiO2 wastes[…]

Physico-chemical and radioactive characterization of TiO2 undissolved mud for its valorization

Posted on by admin

Abstract In order to find a potential valorization of a waste generated in the industrial process devoted to the production of TiO2 pigments, and as an essential and basic step, this waste must firstly be physically and chemically characterized. Moreover, the content of radioactivity is taken in to account due to it comes from a Read more about Physico-chemical and radioactive characterization of TiO2 undissolved mud for its valorization[…]
