Abstract
The development of a non-toxic, and low-cost material that offers good shielding against harmful ionizing radiation is highly demanded. This work offers a strategy for combining ceramic composites and carbon nanotubes to produce composites with desirable radiation shielding properties. First, we successfully prepared barium titanate (BT) ceramic by sol-gel auto-combustion method. Then, a series of CERAM-1, CERAM-2, and CERAM-3 ceramic composites were formed by inserting into BT different types of ferrite and carbon nanotubes. The crystal structural analysis indicated that all ceramic composites crystallized into a cubic structure. The crystallite sizes of the final products were calculated and were found to be 30.8 nm, 25.4 nm, 35.9 nm, and 33.1 nm for pure BT, CERAM-1, CERAM-2, and CERAM-3, respectively. The gamma radiation shielding parameters were experimentally examined at four energies ranging from low to high energy radiation. At 0.06 MeV, the ceramics have the greatest linear attenuation coefficient (LAC) values, ranging from 31.760 to 29.683 cm−1. The results showed that CERAM-1 has the greatest LAC values at 0.060 and 0.662 MeV, which indicated that CERAM-1 is the most effective shield to its advantage over the other ceramic samples at low and middle energies. Based on the obtained results, it can be concluded that various prepared ceramics can be useful for low-energy radiation protective applications.
