Ion-induced amorphization in ceramic materials

High energy heavy ion induced structural disorder in Li2TiO3

“…The disorder region caused by the ion irradiation has been observed for magnetic oxides to be formed along the track of the high energy ion [11] and also numerous other oxides and other ceramics [5,6]. The track morphology depends on the value of the energy loss for the high energy ions.…”

“…In spite of this, little is yet known about the mechanism of the above effects for Li 2 TiO 3 [3,4]. Many are known about those for other oxides [2,5,6]. Recent studies [2,5,6] have shown that ionization due to electronic stopping power can play an important role in radiation damage in ceramics.…”

“…Many are known about those for other oxides [2,5,6]. Recent studies [2,5,6] have shown that ionization due to electronic stopping power can play an important role in radiation damage in ceramics. So, it is necessary to examine the effects of ionization on ceramic fusion materials such as solid breeder materials, insulators, etc.…”

Amorphization of sapphire induced by swift heavy ions: A two step process

“…Because of the excellent physicochemical properties for many industrial applications (hardness, chemical insensitivity, refractory behaviour, transparency over a wide wavelength range) of Al 2 O 3 , many investigations have been performed modifying the microstructural [1][2][3][4][5][6][7], surface state [8][9][10] and optical properties [11][12][13][14][15][16] induced in aAl 2 O 3 by ion irradiation in the electronic energy loss regime. These modifications result from complex interactions involving the slowing down process of the incident ions that induces defect creation and structural transformations in the host matrix [17].…”

Uniform behavior of insulators irradiated by swift heavy ions

“…In Fig. 2 we show such data for ZrSiO 4 [7], MgAl 2 O 4 [8], Al 2 O 3 [8], KTiOPO 4 [9], and Y 2 O 3 [10] which were obtained in experiments with LO or HI projectiles. In the case of Al 2 O 3 and MgAl 2 O 4 , R e values have been also measured in a range of S e but track re-crystallization reduced the initial track sizes.…”
