Embodiment 1
[0041] A glass-ceramic material for synergistic protection against neutrons and gamma rays and a preparation method thereof. The preparation method described in this embodiment is:
[0042] Step 1, using ethanol as the ball milling medium, according to the mass ratio of zirconia grinding balls: aluminum borate powder is 2: 1, the aluminum borate powder is ball milled to a particle size of less than 0.147mm to obtain a ball mill; then the ball mill Dry at room temperature for 20 hours and crush to obtain an aluminum borate precursor.
[0043] Step 2: Take 30.0wt% boron oxide, 30.0wt% bismuth oxide, 10.0wt% phosphorus oxide, 10.0wt% silicon oxide, 10.0wt% barium oxide and 10.0wt% gadolinium oxide as raw materials, mix well , to obtain the mixture I; then the mixture I was melted at 1400°C, quenched in water, then dried at 100°C for 15 hours, and crushed to a particle size of less than 0.147mm to obtain a glass shielding agent containing radiation shielding components .
