By heating a sample of Tb/Na tobermorite we obtained a phase which was identified through its X-ray diffraction (XRD)pattern, as terbium silicate apatite. Subsequently this compound has been directly prepared by solid state reaction and we carried out a structural refinement from XRD data in space group P63/m obtaining cell parameters a = 9.39199(4) Å and c = 6.84041(5) Å. Terbium silicate apatite heated in melted NaF led to Tb4O7 crystals.

Abstract
By heating a sample of Tb/Na tobermorite we obtained a phase which was identified through its X-ray diffraction (XRD)pattern, as terbium silicate apatite. Subsequently this compound has been directly prepared by solid state reaction and we carried out a structural refinement from XRD data in space group P63/m obtaining cell parameters a = 9.39199(4) Å and c = 6.84041(5) Å. Terbium silicate apatite heated in melted NaF led to Tb4O7 crystals.File in questo prodotto:
