Abstract

A new diamond-anvil cell apparatus for in situ synchrotron X-ray diffraction measurements of liquids and glasses, at pressures from ambient to 5 GPa and temperatures from ambient to 1300 K, is reported. This portable setup enables in situ monitoring of the melting of complex compounds and the determination of the structure and properties of melts under moderately high pressure and high temperature conditions relevant to industrial processes and magmatic processes in the Earth's crust and shallow mantle. The device was constructed according to a modified Bassett-type hydrothermal diamond-anvil cell design with a large angular opening (θ = 95°). This paper reports the successful application of this device to record in situ synchrotron X-ray diffraction of liquid Ga and synthetic PbSiO glass to 1100 K and 3 GPa.

摘要

报道了一种新型金刚石压腔装置，用于在从环境压力到5吉帕、温度从环境温度到1300开尔文的条件下对液体和玻璃进行原位同步加速器X射线衍射测量。这种便携式装置能够原位监测复杂化合物的熔化情况，并确定在与工业过程以及地壳和上地幔岩浆过程相关的中等高压和高温条件下熔体的结构和性质。该装置是根据一种改进的巴塞特型热液金刚石压腔设计制造的，具有大角度开口（θ = 95°）。本文报道了该装置成功应用于记录液态镓和合成硅酸铅玻璃在1100开尔文和3吉帕压力下的原位同步加速器X射线衍射情况。
