A combination of transmission electron microscopy and neutron powder diffrac-tion indicate that the final composite consists in 5-6 nm semi-conducting Bi nanowires confined in insulating mesoporous -quartz. Such a nanostructured material could be of considerable interest for thermo-electric applications. HIGHLIGHTS:  Bismuth was inserted into 4-6 nm silica nanotubes under high-pressure, high-temperature conditions  The host amorphous nanotubes crystallize in the form of -quartz  The obtained nanocomposite consists of 5-6 nm Bi nanowires imbedded in mesoporous -quartz  The formation of Bi nanowires modifies their physical properties compared to bulk Bi %G English %2 https://hal.umontpellier.fr/hal-02498343/document %2 https://hal.umontpellier.fr/hal-02498343/file/Zhao_Bi_nano_SSS_version_finale.pdf %L hal-02498343 %U https://hal.umontpellier.fr/hal-02498343 %~ UGA %~ CNRS %~ ENSC-MONTPELLIER %~ INPG %~ NEEL %~ ICG %~ L2C %~ INC-CNRS %~ NEEL-MRS %~ MIPS %~ CHIMIE %~ UNIV-MONTPELLIER %~ TEST-HALCNRS %~ UGA-EPE %~ UM-2015-2021
