Annual demand for impact diamonds may be 1 billion carats, expert says

Scientists say impact diamonds have absolutely unique technology features
KRASNOYARSK, April 12. /TASS/. Development of the Popigai deposit of impact diamonds in the Krasnoyarsk Region’s north will offer new raw material to the global industry. An annual demand for it in various sectors may be up to 1 billion carats. Development of the resources, which formed after a meteorite hit the Earth 36 million years ago, will require common efforts of the Krasnoyarsk Region and Yakutia, experts told TASS.

Presently, the global industry uses natural technical and artificial diamonds; most of them are made in China. The annual global consumption of synthetic diamonds is 15-16 billion carats. Scientists say impact diamonds (which develop from graphite rocks at the time an asteroid hits the Earth) have absolutely unique technology features. For example, they can process materials twice or 2.5 times quicker than synthetic or natural technical diamonds. Their wear resista ....

Diamonds need voltage

Diamond, like graphite, is a special form of carbon. Its cubic crystal structure and its strong chemical bonds give it its unique hardness. For thousands of years, it has also been sought after as both a tool and as a thing of beauty. Only in the 1950s did it become possible to produce diamonds artificially for the first time.
Most natural diamonds form in the Earth s mantle at depths of at least 150 kilometres, where temperatures in excess of 1500 degrees Celsius and enormously high pressures of several gigapascals prevail - more than 10.000 times that of a well-inflated bicycle tyre. There are different theories for the exact mechanisms that are responsible for their formation. The starting material is carbonate-rich melts, i.e. compounds of magnesium, calcium or silicon which are rich in both oxygen and carbon. ....
