NMR AND IR INVESTIGATION OF ALUMINOSILICATE GLASSES AS COMPONENTS OF DENTAL MATERIALS. Authors: S. SIMON, M. VASILESCU, M. MOLDOVAN, VIORICA SIMON. |

Abstract: Aluminosilicate glasses containing approximately the same Al2O3 amount, usable as component of dental materials, are investigated by means of 27Al Magic Angle Spinning Nuclear Magnetic Resonance (MAS-NMR) and Fourier transform infrared (FTIR) spectroscopies. Beside oxide components the sample also contain fluoride and the investigated glass powders were treated with silane. The local order around aluminium differs in the investigated samples showing changes of aluminium coordination function of glass composition. NMR technique is more sensitive than IR to describe the local aluminium environment in aluminosilicate glass systems, but IR is much proper to describe the silanisation of these glasses for a better adhesion to bone. | |||||||
