| Popis: | The thermal expansion coefficients of a number of phenacites [Be2SiO4, β‐Si3N4, β‐Sialon, α‐LiAlSiO4, Zn2SiO4, CdAl2O4, and Zn2GeO4] at temperatures at and above the Debye temperature are analyzed in terms of the thermal Gruneisen parameter γ. The phenacites have γ values intermediate between adamantine crystals and quartz. Values of γ between 0.3 and 0.7 are found. A useful correlation exists between γ and the average volume per anion bond W. Values of γ approaching zero occur for sufficiently large values of W. |
