Kawai-type Large Cavity Press

The Kawai‑type high‑temperature high‑pressure large‑volume press is a classic octahedral‑assembly multi‑anvil press and a benchmark model for second‑stage compression technology. Built upon the proven 6‑8 compression configuration and paired with tungsten carbide second‑stage anvils, it can stably generate ultra‑high pressure and temperature fields. The equipment features high overall load‑bearing capacity, large sample‑chamber volume and broad sample compatibility. Its temperature‑control system delivers stable output of temperatures exceeding 2000 °C with excellent linearity in pressure control. Boasting solid technical heritage and strong compatibility, this model allows replacement of anvil assemblies of different specifications according to experimental requirements. It is widely applied in research fields including high‑pressure phase‑transition studies, high‑temperature‑superconducting material synthesis, planetary‑science simulation, and pre‑experiments for industrial mass production of superhard materials
