Abstract

We have developed a high-pressure furnace assembly with a commercially available chemical-vapor-deposition synthesized boron-doped diamond heater consisting of four strips for large-volume multi-anvil presses (LVPs). This assembly successfully generated temperatures up to 2990 K at 15 GPa. It also has highly reproducible power-temperature relations, enabling us to estimate temperature from power reliably. It can be used for experiments above 9 GPa and is particularly useful for synchrotron x-ray experiments because of the x-ray transparency. It is also competitive in price. This technique is, thus, practical in various LVP experiments in the diamond-stability field.

摘要

我们开发了一种高压炉组件，其具有市售的化学气相沉积合成的掺硼金刚石加热器，该加热器由四条带组成，用于大体积多砧压机（LVP）。该组件在15 GPa压力下成功产生了高达2990 K的温度。它还具有高度可重复的功率-温度关系，使我们能够可靠地根据功率估算温度。它可用于9 GPa以上的实验，并且由于X射线透明性，对于同步加速器X射线实验特别有用。其价格也具有竞争力。因此，该技术在金刚石稳定领域的各种LVP实验中具有实用性。
