Abstract : Many crystals of potassium tantalate-niobate (KTN) were grown. Several large cubes of good optical quality were produced. The best of these had a low d-c conductivity and good a-c and d-c electrooptic behavior over the entire section of the crystal. Extinctions as high as 20 db were measured for an aperture of 5 mm. The literature search for complex perovskites yielded about 450 compounds. The computer programs to generate complex perovskites are ready for final processing. An iridium-strip furnace is ready for exploratory fusions of new compositions. (Author)
