  4. Thorium (Th), radioactive chemical element of the actinoid series of the periodic table, atomic number 90; it is a useful nuclear reactor fuel. Thorium was discovered (1828) by Swedish chemist Jöns Jacob Berzelius. It is silvery white but turns gray or black on exposure to air
  5. Thorium may be three times more abundant on Earth than uranium, it is difficult to estimate, and can also be used in nuclear reactors. In addition, thorium and uranium deposits do not necessarily occur at the same places, thus countries with large potential uranium resources may well have very little thorium and vice-versa
  6. 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 high-quality solid fuel. Additionally, Th is quite inert, making it difficult to chemically process. This is irrelevant for fluid-fueled reactors discussed below

(Thor, Scandinavian god of war) Discovered by Berzelius in 1828. Much of the internalheat the earth produces has been attributed to thorium and uranium. Because of its atomicweight, valence, etc., it is now considered to be the second member of the actinide seriesof elements. Sources. Thorium occurs in thorite and in thorianite Although thorium (90 Th) has 6 naturally occurring isotopes, none of these isotopes are stable; however, one isotope, 232 Th, is relatively stable, with a half-life of 1.405×10 10 years, considerably longer than the age of the Earth, and even slightly longer than the generally accepted age of the universe Most widespread minerals containing Thorium; This list of minerals containing Thorium is built from the mindat.org locality database. This is based on the number of localities entered for mineral species and is therefore slanted towards minerals interesting to collectors with less coverage of common rock-forming-minerals so it does not give an undistorted distribution of Thorium mineral species The Lich is a difficult Hardmode boss, that can be summoned after obtaining Hallowed Bars, Souls of Night and Pumpkins.The Lich can be fought right after killing at least one Mechanical Boss, but it is highly discouraged due to the difficulty of the encounter Th - Thorium Introduction Thorium is a member of the actinide series of elements, along with U and the human-made elements such as Pu. The element has an atomic number of 90, an atomic mass of 232, one main oxidation state (+4) and one naturally occurring isotope (232Th). Like U, it is a radioactive elemen

232 Th is the predominant isotope of natural thorium. If this fertile material is loaded in the nuclear reactor, the nuclei of 232 Th absorb a neutron and become nuclei of 233 Th. The half-life of 233 Th is approximately 21.8 minutes. 233 Th decays (negative beta decay) to 233 Pa (protactinium), whose half-life is 26.97 days Thorium was discovered by J ö ns Jacob Berzelius in 1828. Its name is derived from Thor, the god of war in the Scandinavian mythology. Thorium chemistry is dominated by the tetravalent thorium ion (Th 4+). Its ionic radius is very similar to that of the trivalent cerium ion (Ce 3+) Other articles where Thorium-232 is discussed: fissile material: the fertile materials uranium-238 and thorium-232, respectively. A fertile material, not itself capable of undergoing fission with low-energy neutrons, is one that decays into fissile material after neutron absorption within a reactor

Thorium Metal (Th) Precautions: Powdered thorium metal will often ignite spontaneously in air (it is pyrophoric) and should be handled carefully. Natural thorium decays very slowly compared to many other radioactive materials, and the alpha radiation emitted cannot penetrate human skin

Thorium reactors work by breeding Th-232 through Protactinium-233 (27.4 day half life) and into Uranium-233, which is fissile. Pa-233 is a pretty strong neutron absorber, so the MSBR (basically the LFTR) has to extract it from the core once it is produced and let it decay to U-233 away from the neutrons Thorium is also found in the minerals thorite (thorium silicate) and thorianite (mixed thorium and uranium oxides). The isotope thorium-230, a decay product of uranium-238, is found in uranium deposits as well as in uranium mill tailings. How Is It Used? The principal use of thorium has been in the preparation of the Welsbach mantle for. With a standard reduction potential of −1.90 V for the Th4+/Th couple, it is somewhat more electropositive than zirconium or aluminum. Finely divided thorium metal can exhibit pyrophoricity, spontaneously igniting in air. When heated in air, thorium turnings ignite and burn with a brilliant white light to produce the dioxide

Isotopes of Thorium. All isotopes of thorium are unstable. Th-232 is the most stable and abundantly existing isotope with half-life approximately equal to the age of universe and about three times the age of the earth.

The toxicity of thorium metal has not been quantified. Thorium may be a skin, eye, and mucous membrane irritant, as well as a nephrotoxin. Thorium metal usually does not constitute an external radiation exposure hazard since it emits mainly alpha-radiation at a low energy level This is a mixture of powder and lumps of actual thorium metal. It's radioactively quite hot, and because thorium emits high energy particles, the radiation is not stopped by the miserable sixteenth inch of lead equivalent in our Hot Box display case. I made a special lockable container, called The Can to hold this and the uranyl nitrate Thorium is found in various minerals like monazite and thorite. It is used in making strong alloys, in ultraviolet photoelectric cells. It is a common ingredient in high-quality lenses. When bombarded with neutrons thorium creates uranium-233, a nuclear fuel. The price of 99.8 % pure thorium powder is 464.20 € for 10 g Among TENORM, thorium is prevalently (99%) present in the form of thorium-232 (232 Th) as thorite and thorianite, whereas after mining activities, 232 Th is usually concentrated as thorium dioxide (ThO 2) (Table 12.1). After most of the thorium is removed from the rocks, these are called depleted ore or tailings
