Network Covalent Solids02:18

Network Covalent Solids

13.4K
Network covalent solids contain a three-dimensional network of covalently bonded atoms as found in the crystal structures of nonmetals like diamond, graphite, silicon, and some covalent compounds, such as silicon dioxide (sand) and silicon carbide (carborundum, the abrasive on sandpaper). Many minerals have networks of covalent bonds.
To break or to melt a covalent network solid, covalent bonds must be broken. Because covalent bonds are relatively strong, covalent network solids are typically...

Phase Transitions: Sublimation and Deposition

17.1K
Some solids can transition directly into the gaseous state, bypassing the liquid state, via a process known as sublimation. At room temperature and standard pressure, a piece of dry ice (solid CO2) sublimes, appearing to gradually disappear without ever forming any liquid. Snow and ice sublimate at temperatures below the melting point of water, a slow process that may be accelerated by winds and the reduced atmospheric pressures at high altitudes. When solid iodine is warmed, the solid sublimes...

Area of Science:

  • Materials Science
  • Chemistry
  • Geology

Background:

  • Natural graphite is a critical material facing potential shortages.
  • Synthetic graphite production is essential for future material needs.
  • Anthracite and iron oxide mixtures offer a pathway to synthetic graphite.

Purpose of the Study:

  • To investigate the formation of core-shell structured synthetic graphite.
  • To explore a two-step synthesis method using anthracite and almandine (3FeO·Al2O3·3SiO2).
  • To elucidate the mechanism behind core-shell structure formation during graphitization.

Main Methods:

  • A two-step heat treatment process was employed.
  • Almandine particles were heat-treated to form glass-phase spheroids (core).
  • Deashed anthracite was graphitized on the spheroid surface (shell).
  • Characterization included X-ray Diffraction (XRD), Raman spectroscopy, Scanning Electron Microscopy-Energy Dispersive X-ray Spectroscopy (SEM-EDS), and Transmission Electron Microscopy (TEM).

Main Results:

  • Uniform-sized glass-phase spheroids were successfully formed from almandine.
  • Core-shell structured graphite was synthesized with anthracite graphitized on the spheroid cores.
  • Characterization confirmed the formation of the desired graphite structure.
  • A formation mechanism model was proposed involving spheroid melting and layer-by-layer carbon deposition.

Conclusions:

  • The two-step method effectively produces core-shell structured synthetic graphite.
  • The proposed formation mechanism explains the process under varying temperatures.
  • Findings provide theoretical guidance for the synthetic graphite industry and coal chemistry.
  • This research contributes to addressing natural graphite scarcity through synthetic alternatives.
