What color is thorium?

When pure, thorium is a silvery white metal which is air-stable and retains its lustre for several months. When contaminated with the oxide, thorium slowly tarnishes in air, becoming grey and finally black. Thorium oxide has a melting point of 3300°C, the highest of all oxides.

What texture is thorium?

Pure thorium metal is an air-stable silvery white which can retain its luster for months. Pure thorium is soft, very ductile, and capable of being drawn, swaged, and cold-rolled.

Why is thorium Colourless?

Owing to thorium(IV)'s lack of electrons in 6d and 5f orbitals, the tetravalent thorium compounds are colourless.

Is thorium transparent translucent or opaque?

Its lustre is vitreous, resinous to greasy and is transparent in thin splinters. A distinct cleavage is present and the fracture is conchoidal in form. It is a brittle mineral with a hardness of 4.5 to 6. The specific gravity is high between 6.6 and 7.3.

What color is thorium oxide?

Thorium dioxide (ThO₂), also called thorium(IV) oxide, is a crystalline solid, often white or yellow in colour.

Thorium and the Future of Nuclear Energy

Does thorium glow in the dark?

So no... radioactive elements do not glow in any color you can see.

Is thorium a green energy?

Palgrave Macmillan, 2012, 272 pp.

What does pure thorium look like?

It is silvery white but turns gray or black on exposure to air. It is about half as abundant as lead and is three times more abundant than uranium in Earth's crust.

How rare is thorium?

Thorium is found in small amounts in most rocks and soils. Soil commonly contains an average of around 6 parts per million (ppm) of thorium. Thorium occurs in several minerals including thorite (ThSiO₄), thorianite (ThO₂ + UO₂) and monazite. Thorianite is a rare mineral and may contain up to about 12% thorium oxide.

How radioactive is thorium glass?

A radioactive lens that contains thorium will give off approximately 0.01 millirem (mrem) per hour.

Can I touch thorium?

* Thorium Nitrate emits radioactive particles which can be breathed in or swallowed, or can penetrate the skin. * Thorium Nitrate can irritate the skin causing a rash or burning feeling on contact.

Why isn't thorium widely used?

Thorium doesn't work as well as U-Pu in a fast reactor.

While U-233 an excellent fuel in the slow-neutron regime, it is between U-235 and Pu-239 in the fast spectrum. So for reactors that require excellent neutron economy (such as breed-and-burn concepts), Thorium is not ideal.

What color does thorium glow?

When heated in air, thorium turnings ignite and burn with a brilliant white light to produce the dioxide.

Is thorium a rare earth mineral?

Rare earth minerals are processed primarily from ores and minerals that naturally contain uranium and thorium.

What rock is thorium found in?

Thorium is relatively enriched in acid igneous rocks, especially in granites. The most common thorium mineral is monazite. In uranium ore deposits, thorium is concentrated in thorite and thorianite. In magmatic carbonate-enriched rocks (carbonatites), thorium is associated with rare earth elements (REE) in bastnaesite.

What are some cool facts about thorium?

Where is thorium found in the USA?

More than 200 thorium-rich veins in the Beaverhead Mountains form the Lemhi Pass district, Idaho and Montana. This district is thought to contain the largest concentration of thorium resources in the United States and is the site of renewed thorium exploration activity.

Which country has most thorium?

Is it illegal to own thorium?

Where as thorium releases alpha rays, which can be blocked by human skin, and are as such no (generally) dangerous. That's why its perfectly legal to own a chunk of thorium (though I'd assume you'd be put on some lists if you start buying the stuff), and not uranium.

How poisonous is thorium?

And there is research evidence that inhaling thorium dust increases the risk of lung and pancreatic cancer. Individuals exposed to thorium also have an increased risk of bone cancer because thorium may be stored in bone.

How many years of thorium is left?

Thorium nuclear waste only stays radioactive for 500 years, instead of 10,000, and there is 1,000 to 10,000 times less of it to start with.

Is thorium a rock or a metal?

Thorium (chemical symbol Th) is a naturally occurring radioactive metal found at trace levels in soil, rocks, water, plants and animals. Thorium is solid under normal conditions.

Is thorium flammable?

ICSC 0337 - THORIUM. Highly flammable if powdered. Finely dispersed particles form explosive mixtures in air. NO open flames, NO sparks and NO smoking.

Can thorium reactors be weaponized?

Can Thorium be Weaponized? Although some wonder if thorium can be used in nuclear weapons and are concerned about the possibility of a thorium bomb, thorium actually can't be weaponized because it doesn't produce enough recoverable plutonium, which is required for building nuclear weapons.

How much does thorium cost?

The salts cost roughly $150/kg, and thorium costs about $30/kg. If thorium becomes popular, this cost will only decrease as thorium is widely available anywhere in the earth's crust.
