Abstract
The present invention is generally related to high pressure cells used for high pressure and spectroscopic studies. More particularly, the present invention is directed to the use of moissanite in a high pressure cell or a high pressure press as the anvil and/or gasket material. Additionally, the invention relates to the methods of applying pressure to a sample in a high pressure cell and the method for applying pressure to multiple samples in a high pressure cell.
Claims8
A high pressure cell for studying a sample of a material at high static pressure, wherein said cell comprises:
- first and second moissanite anvils each having a beveled surface between a side surface and culet surface, wherein each culet surface is circular and configured as a spectroscopic window for examining the sample;
- a gasket positioned between said anvils such that the beveled surface and the culet surface of each anvil are in contact with the gasket;
- a pocket in the gasket for receiving the sample positioned between the culet surfaces of the first and second moissanite anvils.
A high pressure cell for studying a sample of a material at high static pressure, wherein said cell comprises:
- first and second moissanite anvils each having a beveled surface between a side surface and culet surface, wherein each culet surface is configured as a spectroscopic window for examining the sample and a beveled surface of at least one anvil is at an angle of about 1°-30° with respect to the culet surface of the at least one anvil;
- a gasket positioned between said anvils such that the side surface, beveled surface and the culet surface of at least one anvil are in contact with the gasket;
- a pocket in the gasket for receiving the sample positioned between the culet surfaces of the first and second moissanite anvils.
