what are diamonds made of? what kind of enviorment are diamonds found in?where in the world are dimonds found?

Question

other than jewlery, what are diamonds used for?


i need answers ASAP!!!!!!!!!(AS SOON AS POSSIBLE!!!!!!!!!!!!!!)


THANX!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!

Answer 1

diamonds are made of carbon.
A diamond is a transparent crystal of tetrahedrally bonded carbon atoms. Diamonds have been adapted for many uses because of the material's exceptional physical characteristics. Most notable are its extreme hardness of diamond, its high dispersion index, and high thermal conductivity.

There form under extreme heat and pressure.
Diamonds are formed by prolonged exposure of carbon bearing materials to high pressure and temperature. On Earth, the formation of diamonds is possible because there are regions deep within the Earth that are at a high enough pressure and temperature that the formation of diamonds is thermodynamically favorable. Under continental crust, diamonds form starting at depths of about 150 kilometers (90 miles), where pressure is roughly 5 gigapascals and the temperature is around 1200 degrees Celsius (2200 degrees Fahrenheit).

Where are they found?
Historically diamonds were known to be found only in alluvial deposits in southern India; India led the world in diamond production from the time of their discovery in approximately the 9th century BCE to the mid-18th century CE, but the commercial potential of these sources has been exhausted. The first non-Indian diamond source was found in Brazil in 1725. While no commercial diamond production exists in the US, Arkansas is the only state to have a verifiable source of diamonds. Today, most commercially viable diamond deposits are in Africa, notably in South Africa, Namibia, Botswana, the Democratic Republic of Congo, Angola, Tanzania and Sierra Leone [5]. There are also commercial deposits being actively mined in the Northwest Territories of Canada, Siberia (mostly in Yakutia territory, for example Mir pipe and Udachnaya pipe), Brazil, and in Northern and Western Australia. Diamond prospectors continue to search the globe for diamond-bearing kimberlite and lamproite pipes.

What are they used for?
The dominant industrial use of diamond is in cutting, drilling, grinding, and polishing. Most uses of diamonds in these technologies do not require large diamonds; in fact, most diamonds that are gem-quality except for their small size, can find an industrial use. Diamonds are embedded in drill tips or saw blades, or ground into a powder for use in grinding and polishing applications. Specialized applications include use in laboratories as containment for high pressure experiments (see diamond anvil), high-performance bearings, and limited use in specialized windows.

Answer 2

Diamonds are made of carbon. Each carbon atom is bonded to four other carbon atoms.

Diamonds are found in and around old "kimberlite pipes." These are places where volcanic explosions took place long ago -- during the explosion, the temperature and pressure were enormous, enough to make the diamond crystals.

Kimberlite pipes, and thus diamonds, are found mainly in Africa. You'll find them in lesser quantities in other parts of the world too.

Diamonds are used to coat cutting and grinding tools.

At some future date, artificial diamonds may be the substrate for a new kind of semiconductor. Artificial diamonds are, at present, too expensive for that.

Answer 3

diamonds are made from carbon and the carbon has been under many tons of pressure for many tens of thousands of years...
and carbon, can be from trees or from dinosaurs...
and they are a lot of them i Africa but are found in many other places in the world, some have been found on a beach, and the people thought they just had a ROCK a real rock, looking smooth and white, not clear and shinny...someone saw it and said hey I think that's a diamond and it was a large one..
they use diamond dust and small diamonds to slowly cut the diamonds to polish them to make all the sides
diamonds that are not up to jewelry standards are use in all kinds of machine shops and used to sharpen other tools and knives..you may even have a diamond knife sharpener in your kitchen...

good luck

Answer 4

Made from: crystallized carbon
Found: Just about everywhere on earth (quality varies)
They are often mined although in some places they are found in rivers and streams, mostly in Africa. Micro diamonds are found in coal; these are currently of no commercial value.
Uses: Drill bits, saw blades, grinders, other industrial cutting tools.

Answer 5

diamonds are made of carbon. pure carbon. they are formed when carbon meets extremes of heat and pressure, therefore they are usually found underground. Africa is a chief exporter of diamonds, as they have diamond mines all over the place

Answer 6

diamonds are made from heating and compressed coal they are found in mines throught africa and israel diamonds are aslo used as a cutting tool for cutting glass plains

Answer 7

diamonds are used as cutting tools also. They are mined in Africa

Answer 8

made of carbon . .under extreme pressure

found in environments where there has been extreme geological pressure

most diamonds are found in south africa . .

Answer 9

diamonds are made of carbon
i think there found in caves somewhere in the world...i'm not sure...but i am sure that their made of carbon
diamonds are used to cut stuff cause its really hard

Answer 10

they are carbon based, they are found in africa, russia has lots of mines and south america, they are used for industrial purposes, cutting tools, lasers, etc.
