Synthesis of magnetic carbon sand [PDF]
AIP Conference Proceedings, 2020 In this work, the magnetic carbon sand (MCS) have been successfully prepared by the chemical vapor deposition (CVD) on sands using adamantane (C10H16) as a precursor. The MCS was obtained by the deposition of adamantane precursor on sand at 1050 °C.
