Ar気流中における1323Kでの窒化物とPdの反応によって、MPd
(M=Gd, Np)が生成することを示した。生成物は、立方晶系のAuCu
型GdPd
(

0.0001nm)及びNpPd
(

0.0001nm)であった。NpNとPdとの反応生成物中には、六方晶系のTiNi
型NpPd
も含まれていた。本研究で得られたMPd
(M=Gd, Np)試料と塩化カドミウムの673Kでの真空雰囲気での固相反応では、塩化物が生成すること、及び、副生成物としてPdで飽和したCd相と金属間化合物PdCdが得られることを示した。
The formation of MPd
(M = Gd, Np) by the reaction of MN with Pd at 1323 K in Ar gas flow was observed. Cubic AuCu
-type GdPd
(
= 0.4081
0.0001 nm) and NpPd
(
= 0.4081
0.0001 nm) were identified, respectively. The product obtained from the reaction of NpN with Pd contained additional phases including the hexagonal TiNi
-type NpPd
. Chlorination of the MPd
(M = Gd, Np) samples was accomplished by the solid-state reaction using cadmium chloride at 673 K in a dynamic vacuum. Pd-rich solid solution phase saturated with Cd and an intermetallic compound PdCd were obtained as by-products of MCl
formation.
