Journal of Crystal Growth 140 (1-2) : 148-156. ScholarBank@NUS Repository. | Abstract: | A pseudo-dendritic crystal growth of lead molybdate (PbMoO4) has been studied with the Czochralski technique. The observed dendritic growth is iso-directional, projecting from the circumference of the growth front, where the content of impurities, melt stoichiometry and temperature are expected to be varied. The dendrite arm length and inter-dendrite angle are closely correlated. It is found that the grown dendrite arms are bounded only by ten low-index crystallographic planes (001), (001), (101), (101), (101), (101), (011), (011), (011), and (011). Based on this work, a facet transition pattern existing among the dendritic arms has been revealed. Further analysis for crystal grains in as-grown PbMoO4 single crystals indicates that a similar dendritic growth can also occur under conventional growth conditions. It is further suggested that the constitutional supercooling is a major factor causing the dendritic growth in PbMoO4 single crystals. © 1994. | Source Title: | Journal of Crystal Growth | URI: | http://scholarbank.nus.edu.sg/handle/10635/81028 | ISSN: | 00220248 |
