It has also been shown that different
cooling rates also resulted in different morphologies
of crystals (Litwinenko, 2001). During crystallization
process, agitation is also essential since it allows
sufficient mobility of the nuclei to encourage crystal
growth. Taylor (1976) observed no change in size or
formation of the crystals once the crystals have been
fully formed during the time of separation whether
agitation are continued or not under the studied
cooling conditions and agitation rate. Studies on the
count and distribution of RBDPO crystals formed
during the crystallization by using Focused Beam
Reflectance Measurement (FBRM) have not been
reported elsewhere. In this paper, crystallization of
RBDPO from the melt was carried out and the effects
of crystallization time and temperature on the crystal
habit of RBDPO were investigated
