| Abstract |
| A systematic study of the synthesis and sintering of a
composition, namely, 9ZnCr20 4.2LiZnV04 in the zinc
chromate-lithium zinc vanadate (ZnCr20 4-LiZnV04) system was carried out. The powders were prepared by both solution
combustion and solid state reaction methods. In solution
combustion technique, stoichiometric mixture of nitrates of
desired cations and urea in aqueous solutions was heated
rapidly to ensue the reaction. Ammonium vanadate was used
as the diluent. In solid state reaction, oxides of zinc, chromium
and vanadium and lithium carbonate were homogenized and
calcined at 800°C. The compound formation was confirmed by
XRD. Compacts of both powders were prepared and sintering
studies were carried out at 1000° and 1100°C. Sintering
behaviour of both the powders were similar. Porosity of sintered
specimens could be varied between 0 and 20% by controlled
sintering. |
