Abstract
Manganese fine particles were prepared by gas-evaporation technique and observed by transmission electron microscope (TEM). A new habit of β-Mn was found, which was a truncated rhombic dodecahedron bounded by twelve (110), twenty-four (210) and eight (111). α-Mn and β-Mn with rodlike habits were identified in addition to tetragonal structure. The tetragonal structure of rodlike particles found by Kimoto and Nishida (Jpn. J. Appl. Phys: 6 (1967) 1017) was revised to be a=1.191 nm and c=0.4585 nm. The tetragonal one transformed to α-Mn at nearly 330°C.Keywords
