THORIUM

(Th) – radioactive chemical. element III gr. periodic table, atomic number 90, mass number 232. Discovered by Berzelius in 1828. Natural Th is an almost pure isotope of Th 232 . Currently, isotopes with mass numbers from 223 to 235 are known, of which the long-lived ones are: Th 228 (T_1/2= 1,91 years), Th 229 (T_1/2 = 7540 years), Th 230 (T_1/2 = 8,10 4 years), Th 232 (T_1/2 = 1,42 10 10 years). The Th isotope is often used for research purposes 234 (T_1/2 =24,1 days) is a β-emitter isolated from uranium preparations. Natural Th is the most commonly used isotope of Th. 232 . According to chemistry properties, it is a typical tetravalent element, due to which it is almost not affected by the redox environment. Th is characterized by the formation of complex compounds with coordination numbers of 8 and 6, of which the most stable are fluoride and sulfate. Most Th compounds are poorly soluble in aqueous solutions (ThO₂,THF₄,Th(C₂O₄)₂ etc.), therefore its migration ability in nature is insignificant. Contains in the earth’s crust. on average 8·10 -4 (wt.% or wt. conc., %) Th. Forms minerals – monacite (thorium and rare earth phosphate), thorite (thorium silicate) and thorianite (thorium and uranium oxide). These minerals are found together with feldspars, quartz, beryl, and zircon in pegmatite veins, greisen, and granites. Monazite is concentrated in placers. The main raw material for the production of Th is monazite. Th is widely used in nuclear engineering and power engineering. A. D. Iskanderova.
