METHOD FOR MAKING MgAl2O4 AMORPHOUS BY HIGH DENSITY ELECTRON EXCITATION

PROBLEM TO BE SOLVED: To provide a method for making a MgAl2 O4 material amorphous. SOLUTION: In the method, the MgAl2 O4 material is made amorphous by an ion irradiating treatment. Specifically, electrons present among Mg, Al, and O, which are the components of the MgAl2 O4 material, are highly den...

Summary:PROBLEM TO BE SOLVED: To provide a method for making a MgAl2 O4 material amorphous. SOLUTION: In the method, the MgAl2 O4 material is made amorphous by an ion irradiating treatment. Specifically, electrons present among Mg, Al, and O, which are the components of the MgAl2 O4 material, are highly densely excited through an ion irradiation of the MgAl2 O4 material, so that the MgAl2 O4 material is changed into an amorphous state from a crystalline state.
