The variation characters of Raman spectra of C-O band-liberation peak ν1 097 of dolomite at the experiment pressure of 100～1 000 MPa and temperature of 298 K were studied using hydrothermal diamond anvil cell(HDAC).

Review of Diamond Anvil Cell for in-situ High-Temperature and High-Pressure Spectroscopic Study;

The Raman spectroscopy of Na_(2)SO_(4) solution was conducted in a diamond anvil cell at temperatures from 30 to(400 ℃) and pressures from 90 to 2400 MPa.

This paper measures the Raman peak displacements of the four vibration modes of S—O bonding and the hydroxyl-stretching vibration modes in the gypsum at high pressures using diamond anvil cell.

Using synchrotron radiation and diamond anvil cell(DAC) in high pressure research station of Beijing Synchrotron Radiation Facility(BSRF),energy dispersive X-ray powder diffraction(EDXD) of the natural enstatite collected from Damapin in Hebei Province,have been in situ measured under room temperature and high pressure(0~31.

The paper introduces the technology improvement on medium frequency furnace for traditional hot pressing diamond bit,such as control on starting scan,medium frequency power supply,automatic adjustment for impedance and temperature control on closed-loop.
