| Abstract: | Results obtained from differential scanning calorimetry and a thermogravimetric analysis of zirconia-based nanocrystalline
powder systems are presented. Heating is found to cause intense mass loss that increases with increase in the MgO content.
Differential scanning calorimetry has revealed that the total energy expended for reactions involved in the powder heating
process increases with increase in the MgO content. The heated powders are characterized by desorption of water. For 10 wt.
% MgO, residual nitrates are seen to decompose into NO2, N2O, or NO. |
