Abstract
A Drickamer‐type apparatus has been made in which the highly‐stressed tip regions of the Carboloy pistons are of dense sintered diamond. Experiments indicate that this apparatus is capable of attaining static pressures of over 400 kilobar on a newly revised scale. The results show that the 1970 revised pressure scale of Drickamer needs further revision downwards for the range above about 150 kilobar. A pressure scale based on electric resistance transitions up to 400 kilobar is proposed. Resistance vs press force curves are shown for Bi, Fe20Co, Fe40Co, CdS, GaP, BP, NaCl, and graphite.Keywords
