If the correlation factor is a constant independent of temperature , Eqs . ( 19 ) and
( 44 ) give identical results experimentally . That is , one normally would perform
experiments to ascertain the diffusion coefficient at various temperatures .

The rate of neck growth has been described by time dependent relationships : x =
ct ( 1 ) where x is the neck radius , t is the time , c is a proportionality constant ,
and m is the exponent dependent upon the sintering mechanism , or ( x / r ) " at (
