"><正> The {0001} face develops on the habit of self-frequency doubling laser crystal Yb: YAI3(B03)4 (YbYAB) only under high growth rate condition, and its morphology is rough. To study the growth... on the {0001} polishing section reflect the crystal growth process. It is shown that the growth morphology on the {0001} polishing section was rough with many hillocks at the first growth stage, and it can......
for ADP crystals. When the supersaturation is low, the advance of growth steps on prismatic face can be blocked by ethanol or impurities, the crystal morphology is changed from the tetragonal prism to shuttle (i.e., the tapered shape). The tapering formation of ADP crystallites was structurally studied in a novel view. Key words:crystal structure; chemical bond; growth habit; ADP; hydrogen bond......
control was discussed on the basic theory of crystal nucleation and growth. It is found that the Cu+ supersaturation is remarkably influenced by the precursor kind, reaction temperature and glucose... in the system. In this case, the solute will mainly precipitate on crystal in a manner of molecular scale growth and monocrystal particles finally form. In an aqueous solution system, the main growth modes......
