High pressure high temperature cell

摘要

A high-pressure high-temperature cell including two or more thermal insulation layers is described. A high-pressure high-temperature cell including a current path through a thermal insulation layer, the current path being electrically connected to a heating element and having an indirect path through the thermal insulation layer, is also described. High-pressure high-temperature press systems including the foregoing high-pressure high-temperature cells alone or in combination are also disclosed.

1. A high-pressure high-temperature cell comprising:
an interior volume; and two or more thermal insulation layers comprising:
a first thermal insulation layer at least partially surrounding the interior volume and comprising a first thermal insulation material selected from the group consisting of cesium chloride (CsCl), cesium bromide (CsBr), cesium iodide (CsI) and combinations thereof and an electrically conductive additive, wherein the first thermal insulation layer has an electrical resistivity of more than 0.1 ohm·cm; anda second thermal insulation layer at least partially surrounding the first thermal insulation layer and comprising a second thermal insulation material, the second thermal insulation material being different from the first thermal insulation material.
