In the present work, we report 29Si solid state NMR studies of several doped lanthanum apatite silicates prepared by hydrothermal method. For the undoped apatite La 9.33Si 6O 26 three peaks are observed at chemical shifts of ∼-77.8, -80.5 and -82.5 ppm, and doped apatite two peaks are observed at chemical shifts of ∼-77 and 78-80.5 ppm, apatite with the more high conductivity show more complex Si NMR spectra. That is indicating a correlation between the silicon environment and the observed conductivity. © 2011 IEEE.[/vc_column_text][vc_empty_space][vc_separator css=”.vc_custom_1624528584150{padding-top: 25px !important;padding-bottom: 25px !important;}”][vc_empty_space][megatron_heading title=”Author keywords” size=”size-sm” text_align=”text-left”][vc_column_text]Apatite-type,High conductivity,Hydrothermal methods,Lanthanum silicates,NMR spectrum,NMR studies,Solid state NMR[/vc_column_text][vc_empty_space][vc_separator css=”.vc_custom_1624528584150{padding-top: 25px !important;padding-bottom: 25px !important;}”][vc_empty_space][megatron_heading title=”Indexed keywords” size=”size-sm” text_align=”text-left”][vc_column_text]29Si NMR,Apatite-type lanthanum silicates,ionic conductivity[/vc_column_text][vc_empty_space][vc_separator css=”.vc_custom_1624528584150{padding-top: 25px !important;padding-bottom: 25px !important;}”][vc_empty_space][megatron_heading title=”Funding details” size=”size-sm” text_align=”text-left”][vc_column_text][/vc_column_text][vc_empty_space][vc_separator css=”.vc_custom_1624528584150{padding-top: 25px !important;padding-bottom: 25px !important;}”][vc_empty_space][megatron_heading title=”DOI” size=”size-sm” text_align=”text-left”][vc_column_text]https://doi.org/10.1109/ICICI-BME.2011.6108653[/vc_column_text][/vc_column_inner][vc_column_inner width=”1/4″][vc_column_text]Widget Plumx[/vc_column_text][/vc_column_inner][/vc_row_inner][/vc_column][/vc_row][vc_row][vc_column][vc_separator css=”.vc_custom_1624528584150{padding-top: 25px !important;padding-bottom: 25px !important;}”][/vc_column][/vc_row]
