A double bevel anvil of the cubic high pressure apparatus (CHPA) was developed, adopting tungsten carbide as the anvil material. We have performed finite element analyses of conventional single bevel anvil and double bevel anvil. The results indicate that the double bevel anvil has two advantages. Firstly, to gain the same chamber pressure, the oil pressure of CHPA using double bevel anvil decreases about 10.8% than that using single bevel anvil. Secondly, double beveling can maintain the pressurized seal stability of the sample chamber, which is often sacrificed with improve the pressure of sample chamber. The results of finite element analyses are well consistent with the experimental results at CHPA (SPD-6x1200 type).
