八面体边长为25 mm的多砧单元组件已被用于涉及高达6.5 GPa和400°C的富水环境的高压研究。  富含水的样品被限制在体积高达300 mm 3的Teflon容器中。通过研究接近金红石-TiO 2-II(105 GPa)相界的无定形二氧化钛颗粒的转变以及接近石英-柯石英(102.5GPa)和柯石英-方石英(107 GPa)相界的无定形二氧化硅颗粒的转变,在250 ° C和400°C之间进行适用性测试。   所进行的实验采用25.4mm的碳化钨砧,其具有15 mm的截断边缘长度。  在接近820 t的载荷下,样品压力估计为6.5 GPa左右。 大体积多砧单元预计将有广泛和不同的应用领域,从模拟地质流体的水热合成和转换/晶体生长在水环境中在千兆帕斯卡的压力。
A multianvil cell assembly with octahedral edge length 25 mm has been adapted for high pressure investigations involving water-rich environments up to 6.5 GPa and 400°C. Water-rich samples are confined in Teflon containers with a volume up to 300 mm3. Applicability tests were performed between 250 and 400°C by investigating the transformation of amorphous titania particles close to the rutile–TiO2-II (∼5 GPa) phase boundary, and the transformation of amorphous silica particles close to the quartz–coesite (∼2.5 GPa) and coesite–stishovite (∼7 GPa) phase boundaries. The performed experiments employed 25.4 mm tungsten carbide anvils with a truncation edge length of 15 mm. The sample pressure at loads approaching 820 t was estimated to be around 6.5 GPa. The large volume multianvil cell is expected to have broad and varied application areas, ranging from the simulation of geofluids to hydrothermal synthesis and conversion/crystal growth in aqueous environments at gigapascal pressures.
