To prevent vaporization damage of BNCT (Boron Neutron Capture Therapy) lithium target during operation, direct synthesis of Li3N thin layer on lithium target surface was demonstrated in 0.1 MPa N-2 gas at temperature below 548 K and the following conclusions were derived; (1) Synthesis of Li3N thin layer on lithium surface was confirmed after nitridation at 276 similar to 548 K with surface contamination by oxygen and carbon. (2) Rapid nitridation over 1 similar to 5 mass%/min was observed above Li melting temperature, whereas slow reaction under 0.02 similar to 0.5 mass%/min below melting temperature. (3) During nitridation, removal of oxygen contamination on Li3N thin layer is taken place by nitrogen below Li melting temperature.
