Abstract We investigated the khatyrkite–cupalite holotype sample, 1.2 × 0.5 mm across. It consists of khatyrkite (Cu,Zn)Al 2 , cupalite (Cu,Zn)Al, and interstitial material with approximate composition (Zn,Cu)Al 3 . All mineral phases sample contain Zn lack Fe that distinguishes them from in Khatyrka meteorite particles (Bindi et al. ; MacPherson Hollister ). Neither highly fractionated natural systems nor geo‐ or cosmochemical processes capable forming are known so far. The bulk chemistry...
The mass spectrometric Knudsen effusion method was used to determine the composition and partial vapor pressures over system in concentration range of 0.1–0.5 mole fraction at 1933 K. new gas molecule compared with individual oxide found this system. formation probability relative volatilities melts can be quantitatively predicted using pressure oxygen systems. correlation shown between thermodynamic properties obtained its phase diagram. experimental values , activities, Gibbs integral...
Abstract The Knudsen effusion mass spectrometric method was used to study the vaporization processes and thermodynamic properties of GeO 2 ·P O 5 system at 1423 K. GeO, PO , P 4 10 GePO 3 molecules were identified in gas phase above system. A correlation shown between diagram attained
The Ca0-Ti0 2 -Si0 system, containing about 10.5 and 16.5 mole % Ti0 was examined at temperatures 1850-2200 Κ using the Knudsen effusion method.Partial pressures of SiO Ο over samples were determined by complete isothermal vaporization method ion current comparison 1850 Si0 activities in system found to have negative deviations from ideality for all compositions except sample with high concentration (Ca0/Si0 =0.6, 16 ).Replacement CaO slags relatively basicity (xfc«c/*si02 > l) causes a...
