Low temperature synthesis of lithium–nitride compound was conducted on the lithium target for BNCT by N2/H2O mixing gas squirt in the ultra high vacuum chamber, and the following results were derived. (1) Lithium–nitride compound was synthesized on the lithium target under 101.3 Pa N2 gas squirt at room temperature and in the ultra high vacuum chamber under the pressure of 1 × 10−8 Pa. (2) Remarkable contamination by O and C was observed on the lithium–nitride compound synthesized under the squirt pressure of 13.3–80 Pa/1.33–4.7 Pa N2/H2O mixing gas. (3) No contamination and synthesis of Li–N compound was observed under the squirt pressure of 0.013–0.027 Pa/0–0.005 Pa N2/H2O mixing gas. (4) Contamination by O and C was enhanced with excessive addition of H2O at the pressure of over 1.33 Pa.
