Ba1-xSrxTiO3　crystals　were　grown　by　optical　floating　zone　method.　The　grown　crystals　of　Ba1-xSrxTiO3(x=0,　0.01,　0.016,　0.02)up　to　6-8　mm　in　diameter　and　up　to　40-80　mm　in　length　was　obtained.　In　the　process　of　experiments　the　solid-liquid　interface　is　convex　to　the　melt,　and　X-ray　double　crystal　rocking　curve　shows　that　the　samples　have　good　quality.　Some　parameters　like　growth　temperature,　growth　speed　and　rotational　speed　were　optimized.　Substitution　of　Sr2+　for　Ba2+　in　BaTiO3　was　effective　in　preventing　the　formation　of　the　hexagonal　phase.　The　infrared　transmittance　of　each　component　crystal　samples　were　over　80%.　The　line,　489-496　cm-1,　has　been　observed　by　Raman　scattering.　A　conclusion　can　be　made　that　there　is　rhombohedral　phase　which　is　related　to　the　Sr-dependent.
