Resistive heating diamond anvil cell

The e - y transition boundary was determined by measuring the resistance changes during the transition in a high-compression belt apparatus (Bundy, 1965) and in an internally heated diamond-anvil cell (Boehler, 1986 Mao et al, 1987). The boundary was also determined by in situ X-ray diffraction measurements in an internally heated diamond-anvil cell (Boehler, 1986 Dubrovinsky et al, 1998), in a laser-heated diamond-anvil cell (Shen et al, 1998), and in a multi-anvil apparatus (Funamori et al, 1996 Lfchida et al, 2001). The boundaries determined by Mao et al. (1987), Shen et al (1998), and Lfchida et al (2001) are in good agreement, but are all at —75 K higher temperature (or —2 GPa lower pressure) than the boundary determined by Funamori et al. (1996), Boehler (1986), and Bundy (1965). 

For diamond anvil cells, heating comes in two distinctive forms, resistive and laser, with the former being more convenient although the upper temperature is considerably less than that obtainable with lasers. Both techniques were pioneered by W.A. Bassett and his coworkers [196, 197]. Two recent reviews [198, 199] provide an excellent introduction to HP-HT methods.
