TLDR
In this paper, the structure of base consiste en cycles a six membres plisses (avec la symetrie de groupe ponctuel 3m) de tetraedres silicate: [Si 6 O 18 ] 12−. Les cycles sont empiles selon le mode cubique compact and maintenus ensemble par les ions Na + et Ca 2+ localises sur quatre positions distinctes.Abstract:
Na 6 Ca 3 [Si 6 O 18 ] cristallise dans R3m avec a=7,488 A, α=89,04°, Z=1 (ou a=10,500 et c=13,184 A, Z=3); affinement jusqu'a R=0,042.

Shell-model molecular dynamics calculations of modified silicate glasses
TL;DR: In this article, a developed potential that includes polarization effects through the shell model (SM) has been validated using available experimental and ab initio structural data, such as density, radial and angular distributions, coordination environments, and network connectivity.

A study of the formation of amorphous calcium phosphate and hydroxyapatite on melt quenched Bioglass(A (R)) using surface sensitive shallow angle X-ray diffraction
TL;DR: In this paper, surface sensitive shallow angle X-ray diffraction was used to study the formation of amorphous calcium phosphate and hydroxyapatite on Bioglass(A (R)) samples, pre-reacted in simulated body fluid (SBF).
