What is Thorium Dioxide (ThO2) used for?
Thorium dioxide adhibitum est in ceramicis calidis, in mantellis gasis, cibus nuclei, flamma spargit, uascula, vitrum opticum non-silicia, catalysis, filamenta in lampadibus incanescentibus, cathodes in tubis electronicis et electrodes arcuum liquescentes.Nuclei fuelsThorium dioxide (thoria) in reactoribus nuclei adhiberi potest ut globulos escarum ceramicarum, typice continentur in baculis cibus nuclei vestitis zirconium admixtis.Thorium non est fissile (sed "fertile", uranium fissile fetum sub bombardario neutro 233);AlloysThorium dioxidum in tungsten electrodes stabiliens in TIG glutino, electronico tubulis, et machinarum turbine gasorum aircraft adhibetur.CatalysisThorium dioxidum prope nullum valorem catalyst commerciale habet, sed huiusmodi applicationes probe exploratae sunt.Catalysta in Ruzicka est magna synthesis anuli.Radiocontrast agentiumThorium dioxidum prima medicamentum in Thorotrast fuit, agens radiocontrast semel commune pro angiographia cerebri adhibita, tamen raram formam cancri (angiosarcoma hepatis) multis annis post administrationem reddit.Vitrum fabricareThorium dioxide vitreo addito adiuvat auget eius index refractiva et dissipatio decrementi.Talis vitrea applicatio in lentibus qualitates invenit pro cameras et instrumentis scientificis.
