摘要：

Flattened diamond crystals were synthesized by the oxy-acetyle flame method under high O2/C2H2 gas ratio conditions (greater-than-or-equal-to 0.95). The morphology of the flattened diamond crystals is characterized as follows: the ratio of the size of the top face and the height is 5:1 or more and all the faces are {111} faces. The twin boundaries are formed many times parallel to the top face. Scanning electron microscopy observations indicate that the flattened diamond crystals exhibit a good crystalline morphology. The motive force of lateral growth is caused by a re-entrant comer effect which results from the formation of twin boundaries.
