milled at speed of 700 rpm for 1 hour by using planetary ball mill and heat treatment at 400, 500
and 600
o
C. The powders were then recovered by removing the salt through a washing procedure
with distilled water and ethanol. Subsequently, powders were characterized by X-ray diffraction
(XRD), scanning electron microscopy (SEM), and particle size analyser. The results indicated
that chemical reaction between reactant mixtures do not occur in milling process, but occur
during heat treatment at low temperature to form powders such as monoclinic zirconia, tetragonal
yttria-stabilized zirconia, lithium chloride and lithium zirconate. The addition of yttria and heat
treatment at 400
o
C and 500
o
C generate more tetragonal structure. On the other hand, yttriastabilized zirconia shows the cubic structure at 600
o
C. Furthermore, the lithium chloride matrix
phases can be removed by using distillation water and ethanol. However, lithium zirconatestill
contains in products phase indicating that lithium zirconate matrix phase cannot be removed by
washing with water due to the solubility constant of lithium zirconate is less than that of lithium
chloride. The average agglomerated size of powders by using distilled water is larger than ethanol
washing. The addition of 6 mol lithium chloride gave smaller average agglomerated size than
that of 2 mol lithium chloride and no addition of lithium chloride. However, the addition of 6 mol
lithium chloride shows the lowest crystallinity. The average agglomerated sizes of powders after
pass through the nanomizer are about 1 m.
