GASKETING MEDIA AT ULTRA-HIGH PRESSURE,
Abstract
The development of new materials to be used as solid pressure transmitting media in ultra-high pressure, high temperature apparatus equipped with x-ray facilities has been investigated. The ultra-high pressure apparatus used was the tetrahedral anvil press designed by Hall. Four composite materials were found to be superior to all others tested: (1) 70% amorphous boron, 30% polyphenylene oxide; (2) 80% amorphous boron, 15% polyphenylene oxide, 5% Nalcon; (3) 80% lithium hydride, 20% polyphenylene oxide; and (4) 90% lithium hydride, 10% polyphenylene oxide. The composites were tested for their stability at high temperature, at atmospheric pressure under inert conditions and at a pressure of 40 kilobars in a tetrahedral anvil press. High pressure calibration experiments were performed for each composite by utilizing resistance transitions in bismuth I to II and II to III at room temperature. The materials have also been rated as effective gasketing materials by comparison to the standard material, pyrophyllite. (Author)
