The direct experimental data of constitutional supercooling during the crystal growth of near-stoichiometric lithium niobate by double crucible Czochralski method were observed and the theoretical issues of the critical growth rate were treated based on the stability criterion equation.

本文在用双坩埚提拉法生长近化学计量比LiNbO3晶体的过程中观察到了组分过冷的实验数据,同时根据Tiller-Chalmers稳定性判据公式半定量计算了近化学计量比LiNbO3晶体临界生长速率的理值,得到一般电阻加热双坩埚提拉法生长近化学计量比LiNbO3晶体的临界生长速率为0。

The maximal critical growth rates of the individual faces for benzophenone crystal, at which the whole faces will vanish in the habits of growing crystals, were calculated by using a three-dimensional crystal model with constant growth rates, and the changes of habits were accordingly predicted.
