Change of ferrite ceramics microhardness under action of high-current pulse beams of low-power electrons

The paper is presenting the first attempt of examination carrying out of high-current pulse beams action effects by low-power electrons on oxide ceramic structures. In capacity of examination object was lithium-titanium ceramics with chemical composition Li0.649Fe1.598Ti0.5Zn0.2Mn0.05104. Irradiation has been carried out in vacuum (P=10-2 Pa) by single pulses of beam of lo power electrons with following parameters: E=15 keV, current density in the pulse 12-25 A/cm2, pulse duration 50 μs, frequency of pulses succession 1 Hz. It is determined, that electron treatment does not provoke noticeable changes on the ceramics phase composition, which preserves its spinel structure
