History[edit | edit source]

Assembly Types[edit | edit source]

Much of the material below comes from Kawazoe, Takaaki. "Multianvil Apparatus".


First stage anvils[edit | edit source]

Kawai-type[edit | edit source]

In the Kawai-type multianvil apparatus (multianvil 6-8 system; Kawai and Endo, 1970), sample pressure is generated by successive compression: 　(1) Hydraulic ram(s) drive six first-stage anvils (via guide blocks). 　(2) The six first-stage anivls compress eight second-stage anvils. 　(3) The second-stage anvils compress an octahedral cell assembly.
