Abstract:
The study investigated linear shrinkage of lithium-titanium ferrite samples during radiation-thermal and
thermal sintering. Prior to compaction, part of the powders were subjected to thermal heating for 2h at
temperatures of 1273, 1373, and 1473 K. It is found that changes in the shrinkage kinetics of ferrites after powder
annealing are consistent with the classical concepts of thermal deexcitation of powders due to annealing of
defects. Such defects were formed in powder grains during grinding. The obtained data analysis allowed us to
offer the most likely model for radiation-thermal activation of powder ferrite sintering. This is a model of
radiation inhibition of non-equilibrium defects relaxation.
