Abstract：

In　this　study,　a　new　type　of　(La0.2Ce0.2Gd0.2Er0.2Tm0.2)2(WO4)3　single-phase　high-entropy　ceramic　(HEC)　powder　was　designed,　prepared　by　solid-phase　synthesis,　and　evenly　mixed　into　an　epoxy　resin　(EP)　matrix　to　test　the　thermal　neutron　and　γ-ray　shielding　performance.　In　terms　of　γ-ray　shielding,　(La0.2Ce0.2Gd0.2Er0.2Tm0.2)2(WO4)3　showed　a　higher　lead　equivalent　value　than　EP　at　65　keV,　indicating　a　clear　shielding　effect　in　the　feeble　absorbing　area　of　lead-based　and　bismuth-based　materials;　moreover,　(La0.2Ce0.2Gd0.2Er0.2Tm0.2)2(WO4)3　showed　good　γ-ray　shielding　performance　in　both　low-energy　and　medium-energy　regions.　In　terms　of　thermal　neutron　shielding,　the　composite　with　the　highest　HEC　content　(EP/W3)　had　a　nearly　100%　shielding　efficiency,　while　that　of　EP　was　approximately　50%,　indicating　that　this　material　has　favorable　thermal　neutron　and　γ-ray　shielding　performance.　Moreover,　the　thermal　conductivity　of　the　resulting　composite　material　was　lower　than　0.3　W·m−1·K−1,　the　tensile　strength　was　higher　than　10　MPa,　and　the　density　was　lower　than　1.5　g·cm−3.　All　these　results　suggest　that　(La0.2Ce0.2Gd0.2Er0.2Tm0.2)2(WO4)3　is　a　candidate　radiation　shielding　material.　©　2021　The　Authors
