Hybrid-anvil: A suitable anvil for large volume cubic high pressure apparatus. | LitMetric
A hybrid-anvil used in cubic high pressure apparatus is presented, which makes it possible to pressurize samples of 36 mm(3) volume up to 5.5 GPa and to heat simultaneously up to 1350-1400 degrees C for routine operation. The hybrid-anvil has been designed based on the theory of multilayered pressure vessels and massive support, which can save weight about 60.00% compared to the traditional anvil. We note from 10 000 times of experiments that the rate of failure crack decreases about 16.67% and the cost of anvil saves about 66.40% after the modification of the anvil. This represents a relatively simple and inexpensive anvil for material synthesis and research.
