当使用碳化钨作为砧材料时，Kawai型多砧装置的最大可达到压力被限制在28GPa。近年来，该装置进行了显著的创新，采用烧结金刚石（SD）作为砧座材料。到目前为止，在SD砧座组件中已经证实了高达63 GPa的压力，而没有任何样品体积的减少。因此，相平衡和熔融实验已经扩展到下地幔深处的条件。
The maximum attainable pressure of the Kawai-type multi anvil apparatus has been limited to 28 GPa when using tungsten carbide as the anvil material. Recently a remarkable innovation has been made for the apparatus by adopting sintered diamond (SD) as the anvil material. So far pressures up to 63 GPa have been confirmed in SD anvil assemblies without any reduction of sample volume. Therefore phase equilibrium and melting experiments have been extended to conditions to deep into the lower mantle.
