May 01, 2019· Thorium Dioxide. on today's (May 1, 2019) front page at Wikipedia (english), a photo of some lenses with varying levels of yellowing, and a link to Thorium Dioxide article Thorium dioxide Wikipedia Interesting to me because the Takumars are instantly identifiable in the image, even before you enlarge it to read the fronts.
On the Practical Use of Lightbridge Thoriumbased Fuels ...
Thorium's improved properties provide a more stable vehicle for storage of used fuel as well. Thorium dioxide will not oxidize in water like uranium dioxide, and therefore retains a larger percentage of the radioactive isotopes even in the breach of a storage container.

Incandescent Gas Lantern Mantles
The thoriumcontaining incandescent mantle was invented in 1884 by Carl Auer von Welsbach, an Austrian chemist, and it is sometimes referred to as a "Welsbach mantle" or "Auerlicht." This invention resulted in the first commercial use of the element thorium. Today, these mantles are ...
Breeder reactor Wikipedia
A breeder reactor is a nuclear reactor that generates more fissile material than it consumes. Breeder reactors achieve this because their neutron economy is high enough to create more fissile fuel than they use, by irradiation of a fertile material, such as uranium238 or thorium232 that is loaded into the reactor along with fissile fuel.

Thorium(IV)oxid – Wikipedia
Thorium(IV)oxid kann als Katalysator bei der Decarboxylierung von Carbonsäuren eingesetzt werden. Gefahren. Thorium(IV)oxid wirkt reizend auf Haut und Augen. Bei Verletzungen kann es in den Körper gelangen und toxisch wirken, beim Einatmen kann es sich in der Lunge ablagern und diese bestrahlen.
ENVIRONMENTAL QUALITY Part XV. Radiation Protection
89. Thorium contained in any finished aircraft engine part containing nickelthoria alloy, provided that: a. the thorium is dispersed in the nickelthoria alloy in the form of finely divided thoria (thorium dioxide); and b. the thorium content in the nickelthoria alloy does not exceed 4 percent by weight. 9.

What is Thorium? (with picture)
Jul 05, 2019· Before the advent of electric lighting, thorium mantles were frequently used as a light source; when heated with a flame, certain thorium dioxide alloys will glow with a dazzling white light. This glow is unrelated to radioactivity and comes from the chemical interactions with cerium and oxygen. Unless swallowed or otherwise taken into the body ...
Why not thorium? –
Making thorium dioxide is expensive, in part because its melting point is the highest of all oxides, at 3,300° C.

A thoriumbased fuel cycle for light water reactors will reduce the plutonium generation rate and enhance the proliferation resistance of the spent fuel. However, priming the thorium cycle with {sup 235}U is necessary, and the {sup 235}U fraction in the uranium must be limited to below 20% to minimize proliferation concerns.

Editor's note: Some chemicals in this database contain more information than others due to the original reason this information was collected and how the compilation was accomplished. While working with material safety data sheets (MSDS), I found that manufacturers sometimes used obscure names for constituent chemicals and I didn't always have a good idea of what I was dealing with.
