| Περίληψη: | Title screen The paper analyzes the possibility of describing the accelerated sintering of lithium-titanium compacts underhigh-power radiation effects in terms of classical physical models developed by Kuczynski and Johnson based onthe kinetic analysis of ferrite compact densification. LiTi ferrites synthesized by ceramic technology in laboratoryconditions were investigated. The first portion of the compacts was sintered in air in thermal ovens at 900–1100°Cfor 30 minutes at a heating rate of 900 °C/min. The second portion of the compacts was sintered in a similar modebut using a radiation-thermal method: the exposure to pulsed electron beam with energy of 1.5–2.0 MeV using theILU-6 accelerator. The geometrical dimensions of the compacts were measured before and after sintering todetermine shrinkage. Mathematical approximation of the experimental shrinkage data showed the discrepancy ofboth models to describe sintering of LiTi ferrite samples both under thermal sintering conditions and radiationthermal effect. |
