Abstract
This article reviews required properties for cylinder material for piston-cylinder high pressure apparatuses, and show that zirconium-based bulk metallic glass (Zr-BMG) has outstanding properties as a cylinder material. The piston-cylinder made of the Zr-BMG cylinder sustains pressures up to ～2 GPa, which is estimated by the pressure dependence of superconducting temperature of lead. The Zr-BMG cylinder is particularly useful for neutron scattering experiments owing to its remarkable transparency for neutron, and also potentially useful for SQUID measurements owing to its relatively low magnetic susceptibility.
