We first found that Mg 14 Si 5 O 24  anhydrous phase B (Anh-B) dissociates to Mg 2 SiO 4  wadsleysite (Wd) and MgO periclase (Per) at about 18 GPa and 1873 K. From the results of the high-pressure experiments, the phase boundaries of 5 Mg 2 SiO 4  forsterite (Fo) + 4 Per = Anh-B and Anh-B = 5 Wd + 4 Per were determined. In addition, the isobaric heat capacity ( C   P  ) of Anh-B was measured by differential scanning calorimetry in the temperature range of 300–770 K and the thermal relaxation method using a Physical Property Measurement System (PPMS) in the range of 2–303 K. From the measured low-temperature  C   P  , the standard entropy ( S ∘ 298.15 ) of Anh-B was determined to be 544.4(2) J/(mol·K). We also performed high-temperature X-ray diffraction measurements in the range 303–773 K to determine the thermal expansivity (α) of Anh-B. The obtained  C   P   and α were theoretically extrapolated to higher temperature region using a lattice vibrational model calculation partly based on Raman spectroscopic data. Thermodynamic calculations by adopting the thermochemical and thermoelastic data for Anh-B obtained in this study and the estimated formation enthalpy for Anh-B of –13 208 kJ/mol gave phase equilibrium boundaries for 5 Fo + 4 Per = Anh-B and Anh-B = 5 Wd + 4 Per that were consistent with those determined by the present high-pressure high-temperature experiments. The results clarified that, in the Mg 14 Si 5 O 24  system, Anh-B is stable between 12 and 18 GPa at the expected temperatures of the Earth’s mantle."}]}],"creator":[{"@id":"https://cir.nii.ac.jp/crid/1420564276187074688","@type":"Researcher","personIdentifier":[{"@type":"KAKEN_RESEARCHERS","@value":"60291522"},{"@type":"NRID","@value":"1000060291522"},{"@type":"NRID","@value":"9000004627502"},{"@type":"NRID","@value":"9000376929241"},{"@type":"NRID","@value":"9000258433093"},{"@type":"NRID","@value":"9000367832755"},{"@type":"NRID","@value":"9000396139363"},{"@type":"NRID","@value":"9000401434402"},{"@type":"NRID","@value":"9000356897206"},{"@type":"NRID","@value":"9000020755797"},{"@type":"NRID","@value":"9000401973715"},{"@type":"NRID","@value":"9000402249893"},{"@type":"NRID","@value":"9000283727649"},{"@type":"NRID","@value":"9000283728902"},{"@type":"NRID","@value":"9000283903602"},{"@type":"NRID","@value":"9000283727863"},{"@type":"NRID","@value":"9000258433821"},{"@type":"NRID","@value":"9000258434972"},{"@type":"NRID","@value":"9000283903678"},{"@type":"NRID","@value":"9000258602955"},{"@type":"NRID","@value":"9000391880500"},{"@type":"NRID","@value":"9000347137895"},{"@type":"NRID","@value":"9000392139957"},{"@type":"NRID","@value":"9000258433673"},{"@type":"NRID","@value":"9000263041860"},{"@type":"NRID","@value":"9000283906477"},{"@type":"NRID","@value":"9000401430745"},{"@type":"NRID","@value":"9000391886423"},{"@type":"NRID","@value":"9000258433246"},{"@type":"NRID","@value":"9000283728917"},{"@type":"NRID","@value":"9000347137914"},{"@type":"NRID","@value":"9000258434967"},{"@type":"NRID","@value":"9000392140475"},{"@type":"NRID","@value":"9000392140531"},{"@type":"NRID","@value":"9000016865946"},{"@type":"NRID","@value":"9000391878303"},{"@type":"NRID","@value":"9000253531577"},{"@type":"NRID","@value":"9000396139373"},{"@type":"RESEARCHMAP","@value":"https://researchmap.jp/read0096582"}],"foaf:name":[{"@value":"Hiroshi
