The glass powder was either densified and crystallized at 1473 K and 0.1 MPa or hot isostatically pressed at 1443 K and 300 MPa confining pressure. Fourier transform infrared spectrometry indicates a water content of 0.002–0.0035 wt % (300–550 H per 10<jats:sup>6</jats:sup> Si) for specimens prepared at atmospheric pressure. Hot‐isostatically pressed samples contain 0.05 wt % to 0.1 wt % (8000–15000 H per 10<jats:sup>6</jats:sup> Si), depending on whether they were crystallized from glass powder predried at 1073 K for 2–3 days or from glass powder as received. In the wet samples, <1 vol % glass was found. Transmission electron microscopy showed that two‐grain boundaries are glass‐free to a resolution of 5 nm. We performed creep experiments at 0.1 MPa pressure with temperatures ranging from 1373 to 1573 K and stresses ranging from 1 to 100 MPa. The mechanical data indicate grain boundary diffusion controlled creep with a stress exponent n = 1.0±0.1 and a grain size exponent m = −2.9±0.2. The activation energy for creep is 585±45 kJ mol<jats:sup>−1</jats:sup> or 377±38 kJ mol<jats:sup>−1</jats:sup> for dry or wet specimens, respectively. If extrapolated to natural temperatures (≅973–923 K), our mechanical data indicate 3–4 orders of magnitude difference in strength between dry samples and specimens containing trace amounts of water.</jats:p>"}]}],"creator":[{"@id":"https://cir.nii.ac.jp/crid/1380567186806322318","@type":"Researcher","foaf:name":[{"@value":"A.
