摘要
Abstract
Bismuth silicate (Bi4Si3O12) micro-crystals with grain line structure were grown by sintering method under atmosphere pressure. The as-grown products were studied using X-ray diffraction and environmental scanning electron microscopy. The grain orientation law was tested by One-Sample Kolmogorov-Smirnov test. The result shows Bi4Si3O12 grains are always distributed in pairs on both sides of a stable line. The angle between grain orientation and the line growth direction obeys the normal distribution on one side of grain line. In a stable line, the mean angle on one side is from 53. 9° to 68. 9°. On one side of a stable line, there is a significant positive correlation between mean angle and mean grain size. When mean angle on one side exceeds 68.9°, the ordered structure on the side is destroyed. The elimination process on the one side has no influence on highly ordered structure on the opposite side.关键词
