Pressure generation to a higher pressure range in a large-volume press (LVP) denotes our ability to explore more functional materials and deeper Earth’s interior. Pressure generated by normal tungsten carbide (WC) anvils in a commercial way is mostly limited to 25GPa in LVPs due to the limitation of their hardness and design of cell assemblies. We adopt three newly developed WC anvils for ultrahigh pressure generation in a Walker-type LVP with a maximum press load of 1000 ton. The hardest ZK01F WC anvils exhibit the highest efficiency of pressure generation than ZK10F and ZK20F WC anvils, which is related to their performances of plastic deformations. Pressure up to 35GPa at room temperature is achieved at a relatively low press load of 4.5MN by adopting the hardest ZK01F WC anvils with three tapering surfaces in conjunction with an optimized cell assembly, while pressure above 35GPa at 1700K is achieved at a higher press load of 7.5MN. Temperature above 2000K can be generated b...

沃克型大容量压力机中35GPa以上的压力产生

大容量压力机（LVP）中产生更高压力范围的压力表示我们有能力探索更多的功能材料和更深的地球内部。普通碳化钨（WC）砧以商业方式产生的压力由于其硬度和电池组件设计的限制，在LVP中大多限于25GPa。我们采用了三台新开发的WC砧座，可在最大压床载荷为1000吨的Walker型LVP中产生超高压。最坚硬的ZK01F WC砧座比ZK10F和ZK20F WC砧座产生压力的效率最高，这与它们的塑性变形性能有关。在相对较低的4压力负载下，室温下可达到35GPa的压力。通过采用具有三个锥形表面的最坚硬的ZK01F WC砧座和优化的电池组件来实现5MN，而在7.5MN的更高压力载荷下，在1700K时压力可达到35GPa以上。可以产生超过2000K的温度
