The Radical growth rates of the selenium spherulites were measured by the microscopic method at temperatures ranging form 128.4°C to 192.3°C. The radial growth rate increased with an increase in the crystallization temperature up to about 180°C, reached a maximum value of 87.0 μ/min, and then decreased abruptly, judging form the observation of organic polymers at crystallization temperatures near their melting points. The process of the spherulite growth of selnium near the melting point could not be interpreted by only two elementary processes, that of the segmental jump and that of the formation of a two-dimensional nucleus of a critical size. The variation in the radial growth rate of selenium with the temperature was explained by considering the bond-breaking process as an elementary process. The estimated surface free energy at the liquid-crystal interface was 25.1 erg/cm<SUP>2</SUP>; this value was a reasonable one.
