Large volume high-pressure generation is dependent on the mechanical properties of the gasket material. High pressure research can often be expensive, time consuming, and limited to few samples. The objective of this research was to provide a simple method for evaluating a wide array of materials for use as gaskets in large volume high-pressure high-temperature applications. In this paper we explore the possibility of using a mixtures model based on the plastic deformation of Co-cemented WC Bridgman anvils and calibrant phase transitions to predict the pressure generation of composite materials. Comparisons to the industry standard of pyrophyllite were done by modeling ZrO2, CaCO3, and sodium bentonite clay. Results show a mixture of 33.3 vol% bentonite and 66.6 vol% ZrO2 closely matches the Co-cemented WC Bridgman anvil mechanical deformation response in addition to the calibrant phase transition curve of pyrophyllite. |
