Abstract

The whole process of the dendrite growth in PGO melt crystal growth was visualized in the $in~situ$
observation system. It was pointed out that the dendrite had relation with the PbO impurity. An
concentration diffusive layer arising from the impurity was observed, and the dendrite growth was
triggered when the diameter of the layer exceeded the critical value about 12$\mu$m. The rate
of the main trunk of the dendrite against the time was measured. It was noted that the rate was
affected by some factors such as the appearance of the branches and the turning of the main
trunk, which was assumed according to our early work.
