Topotactic reduction as a synthetic route for the preparation of low-dimensional Mn(II) oxide phases: the structure and magnetism of LaAMnO(4-x) (A = Sr, Ba)
Autor: Michael A. Hayward, Helen J Kitchen, Ian Saratovsky
Publikováno v: Dalton transactions (Cambridge, England : 2003). 39(26)
Reaction of LaSrMnO(4) with CaH(2) at 420 degrees C yields LaSrMnO(3.67(3)). Raising the temperature to 480 degrees C yields the Mn(II) phase LaSrMnO(3.50(2)). Neutron powder diffraction data show both phases adopt body-centred orthorhombic crystal s

Tungsten carbide, WC, can be prepared by microwave (MW) synthesis in the solid state from its component elements in air on timescales that are orders of magnitude faster than those achieved by conventional heating methods. In a multimode cavity (MMC)
