【Abstract】 In order to grow a fine quality Lithium Niobate（LiNbo₃）crystal,the mixtureratio of sharting materials,thermal field,and annealing and polarizing condieionhave been investigated.（Experiments have carried out with weight-10sing to deter-mine the mixture ratio of the equi-compoment point in the constitution diagramof the Li₂O-Nb₂O₅ system,because of their different weitht-losing at hightemperatures）At the same time,by selecting the reasonable thermal field and expe-rimental conditions the annealing and the polarizing are completed in one step.These crystals have been grown perfectly.Devices for maling Bulk electro-optic modulators,monolithic double 45 electro-optic Q switches,Ti-diffussion optical wave guides and surface acoustic wave（SAW）are stable stable in performance ane good in quality.更多还原
