After a smooth increase up to 1300 K, the volume of β‐cristobalite decreases continuously up to the melting temperature of 2000 K where it is back to the 750 K value of 27.4 cm³/mol. A slightly negative thermal expansion coefficient is also observed for quartz above 1400 K, resulting in a volume of 23.45 cm³/mol at 1673 K. From these results and the molar volume of SiO<jats:sub>2</jats:sub> liquid, the volumes of fusion of β‐cristobalite and quartz are −0.1 and 3.85 cm³/mol, respectively. With these values and the known entropies of fusion, only a slight adjustment to 1673 K of the melting temperature of quartz has been found necessary to ensure consistency with available phase equilibria data.</jats:p>"}]}],"creator":[{"@id":"https://cir.nii.ac.jp/crid/1383670319770183936","@type":"Researcher","foaf:name":[{"@value":"Ekatarina Bourova"}]},{"@id":"https://cir.nii.ac.jp/crid/1383670319770183937","@type":"Researcher","foaf:name":[{"@value":"Pascal Richet"}]}],"publication":{"publicationIdentifier":[{"@type":"PISSN","@value":"00948276"},{"@type":"EISSN","@value":"19448007"}],"prism:publicationName":[{"@value":"Geophysical Research Letters"}],"dc:publisher":[{"@value":"American Geophysical Union (AGU)"}],"prism:publicationDate":"1998-07","prism:volume":"25","prism:number":"13","prism:startingPage":"2333","prism:endingPage":"2336"},"reviewed":"false","dc:rights":["http://onlinelibrary.wiley.com/termsAndConditions#vor"],"url":[{"@id":"https://api.wiley.com/onlinelibrary/tdm/v1/articles/10.1029%2F98GL01581"},{"@id":"https://agupubs.onlinelibrary.wiley.com/doi/pdf/10.1029/98GL01581"}],"createdAt":"2004-02-04","modifiedAt":"2023-11-22","relatedProduct":[{"@id":"https://cir.nii.ac.jp/crid/1050282814174692480","@type":"Article","resourceType":"学術雑誌論文(journal article)","relationType":["isReferencedBy"],"jpcoar:relatedTitle":[{"@language":"en","@value":"Viscous strengthening followed by slip weakening during frictional melting of chert"}]},{"@id":"https://cir.nii.ac.jp/crid/1360576118820421248","@type":"Article","resourceType":"学術雑誌論文(journal article)","relationType":["isReferencedBy"],"jpcoar:relatedTitle":[{"@value":"On the role of intermolecular vibrational motions for ice polymorphs.
