  • Pressurizable dilatometer system and apparatus
    Patent number: 11150205
    Abstract: Dilatometer systems for measuring characteristics of material samples are disclosed. In one embodiment, a dilatometer system includes a reactor adapted to receive the test sample, a density trap in fluid communication with the reactor, a first fluid selectively filling the reactor and a portion of the density trap, and a second fluid selectively filling a portion of the density trap. The first fluid and the second fluid are immiscible with one another and selectively form an immiscible fluid boundary in the density trap. The dilatometer system further includes a heater that selectively heats the first fluid.
    Type: Grant
    Filed: February 20, 2019
    Date of Patent: October 19, 2021
