History edit

Assembly Types edit

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


First stage anvils edit

Kawai-type edit

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.
