【Abstract】 Through comparison of the various kinds of crystal growth from the melt, a metal strip heated zone melting (MSHZM) method has been devised which is particularly suitable for growing off congruent oxide crystals homogeneously. The equipment, advantages and disadvantages, and present research status in China and abroad are described in detail. Our experiments on stoichiometric lithium niobate crystal growth by means of MSHZM are reported and discussed.更多还原
