Lithium borates are promising materials for thermal neutron detection. However, a strong tendency of borates for glass transformation can lower the detection efficiency of some luminescence centres. Here, we describe the synthesis of well-crystalline translucent borate ceramics. The precursor powder of undoped LiSr4(BO3)3 was prepared using a wet homogenization method and then densified to ceramic pellets at different sintering tem- peratures using SPS. As the sintering temperature increased, the degree of densification and crystallite con-nectivity improved, rendering the prepared pellets translucent.
