Abstract

We have generated over 40 GPa pressures, namely, 43 and 44 GPa, at ambient temperature and 2000 K, respectively, using Kawai-type multi-anvil presses (KMAP) with tungsten carbide anvils for the first time. These high-pressure generations were achieved by combining the following pressure-generation techniques: (1) precisely aligned guide block systems, (2) high hardness of tungsten carbide, (3) tapering of second-stage anvil faces, (4) materials with high bulk modulus in a high-pressure cell, and (5) high heating efficiency.

摘要

我们首次使用配备碳化钨砧座的川畸型多砧压机（KMAP），分别在室温及2000K温度下产生了超过40吉帕的压力，即43吉帕和44吉帕。这些高压的产生是通过结合以下压力产生技术实现的：（1）精确对准的导向块系统；（2）碳化钨的高硬度；（3）第二阶段砧面的锥度；（4）高压腔中具有高体积模量的材料；（5）高加热效率。
