采用浮区提拉法从高温溶液中生长了硼酸钾晶体。将K和Nb的起始溶液组成从K：Nb=50：50变更为58：42。晶格常数、晶格体积和相变温度取决于起始溶液的组成。KNbO3晶体附近的固溶体区域被估计为扩展到富K的组合物。
Potassium niobate crystals were grown from high temperature solutions using the floating zone pulling-down technique. The starting solution compositions of K and Nb were changed from K:Nb=50:50 to 58:42. The lattice parameter, lattice volume and phase transformation temperature depended on the starting solution compositions. The solid solution region near the KNbO3crystals was estimated to be expanding to a K-rich composition.
