A preparative solid state chemistry laboratory is set up, where various synthetic techniques including sol-gel and redox precipitation processes, in addition to conventional solid-state high-temperature methods, are been implemented.

The materials straddle to a portfolio of transition metal oxides, mixed-metal chalcogenides, and all the way to hybrid perovksites.

In addition, intermetallic compounds can be grown with an arc-melting furnace (>2000 oC) equipped with a water-cooled copper hearth. The system is easily purged (vacuum & Ar-gas) allowing specimens of metal ingots to be rapidly formed with good purity.

Basic Tools:

  • Glove-boxes for Air- and Moisture- Sensitive Compounds
  • High Vacuum (P<10-4 mbar) or Helium-Flow Glass Line for Medium-Temperature (<1100 oC) for Solid-State Syntheses.
  • High-Temperature Programmable Electric Furnaces (<1600 oC) for Solid-State Reactions.
  • Chemical Vapor Transport Reactions (<1000 oC)
  • Intercalation Reactions ("Soft Syntheses" at 40-80 oC).
  • Solvo-/ Hydro- thermal Reactions (Teflon-lined Autoclaves: 23 mL, 250 oC, 1800 psi).
  • Thermal Evaporator (Thick Film Growth: ~100 μm ).

Where necessary samples are flame sealed in evacuated glass or silica ampules and annealed at the required temperatures.
