| Abstract |
| The enhanced sintering of tin dioxide with additives, viz. Mn02, CuO,
ZnO, Li2C01 and Sb20 3 has been studied under isothermal condition.
The efficiency of different additives in attaining higher density is discussed
in terms of grain growth and pore morphology studied by SEM
fractograph.
The time exponents of the kinetic equation and activation energies
are calculated from isothermal sintering data for various systems and
these parameters are used to interpret the sintering mechanism for
different additives. It has been found that different mechanisms are
predominant in different systems and in some cases it depends on sintering
temperature also. From SEM fractograph it appears that due
to pore trapping within the grains it is not possible to attain higher
density. |
