Symmetrical diamond anvil cell {SYMMETRICAL DIAMOND ANVIL CELL}

The present invention relates to a symmetrical diamond anvil cell, and more particularly, to a symmetrical diamond anvil cell that can be used by anyone and can acquire information on more high pressure properties.

In general, diamond anvil cell is a device for generating a positive pressure and high pressure by compressing the samples contained between a pair of anvils that act as a spectroscopic window. In addition, the high pressure generation region, which plays an important role in recent research and development work, is greatly influenced by the design of the diamond anvil cell and the strength of the materials used.

Conventionally, Brigman, a professor at Harvard University who invented the famous Brigman Enville, found that pressures of about 100 Kbar could be obtained by pressing thin samples between flat pedestals. Brigman also found that if harder materials such as synthetic diamond were used as anvil, much higher pressure could be obtained.

Afterwards, Mao and Bell developed Mao-Bell high-pressure cells, where 0.3 carat of natural diamond was polished to cut the top of the culet. Using a pair of brilliant-cut (16-side) diamond anvils with an area of 0.25 mm2, a 500 Kbar pressure was generated, and further studies have been conducted to generate higher pressures.

Recently used diamond anvil cells are polished by brilliant cut and placed between two diamond anvils with a curet face, placing a gasket containing a sample inside and pressing the two diamond anvils to obtain a static pressure of approximately 600 Kbar. It is. The advantage of the diamond anvil cell is that the sample can be observed through two optically transparent diamonds, and the properties of the sample under high pressure can be measured using a laser method such as spectroscopy or X-ray diffraction.
