Tritium breeder is an important functional material in d-T fusion reactor blanket serving the purpose of tritium re-production and energy conversion. Presently, Li2TiO3 ceramics is considered as the most promising solid tritium breeder for its good chemical stability, high mechanical strength and excellent tritium release performance. However, low lithium content and lithium evaporation at high temperature lead to a low tritium breeding ratio. In the paper the neutron multiplier element, Pb, is introduced into Li2TiO3 to obtain lithium lead titanate (Li2PbxTi1-xO3) as tritium breeder, which combined the advantages of Pb and Li2TiO3 ceramic. Li2PbxTi1-xO3 powders were synthesized via a sol-gel method, employing lithium acetate, tetrabutyl titanate, and lead acetate, with varying lead contents. The characterization results indicate that at a molar ratio of titanium to lead of 1:2, Li2TiO3-Li2PbO3 eutectic phase could be formed. The tritium breeding ratio (TBR) of Li2PbxTi1-xO3 materials were evaluated by Monte Carlo Code, which was notably influenced by the lead content, exhibiting a continuous increase with higher Pb content and neutron energy. The Li2PbxTi1-xO3 pebbles were prepared by freeze-drying route. The mechanical strength of Li2PbxTi1-xO3 pebbles could be affected significantly by the lead content. Compared to the conventional Li2TiO3 ceramics, the Li2Pb0.4Ti0.6O3 ceramics exhibits a higher crushing load of 25.33 N.
