As a congruent-melting compound, a single crystal can be obtained from the melt, but a phase transition (cubic \u21d4 tetragonal) occurs around 110 K at lower temperatures than room temperature. However, due to the characteristic of Ti oxides, which are prone to oxygen deficiency at high temperatures and in reducing atmospheres, it is essential to grow crystals under conditions that do not cause metallization. Therefore, it is difficult to control the atmosphere in growing methods using crucibles and components such as Ir (iridium) and Mo (molybdenum), which oxidize, melt and\/or vaporize at high temperatures, and it is not easy to obtain good quality single crystals with good reproducibility. Although there are reports of good quality crystals being grown by the TSSG (Top Seeded Solution Growth) method using the solution method and the FZ (Floating Zone) method, which does not use crucibles, crystals grown by the Flame-Fusion (Verneuil) method are now widely used commercially due to cost and production volume. <\/span><\/p>\n<p>&nbsp;<\/p>\n<p>&nbsp;<\/p>\n<p><a href=\"https:\/\/www.shinkosha.com\/english\/%e5%8d%98%e4%bd%8d%e6%a0%bc%e5%ad%90\/\"><img loading=\"lazy\" decoding=\"async\" src=\"https:\/\/www.shinkosha.com\/english\/wp-content\/uploads\/sites\/2\/2024\/04\/\u5358\u4f4d\u683c\u5b50-300x184.jpg\" alt=\"\" width=\"300\" height=\"184\" class=\"aligncenter size-medium wp-image-1653\" srcset=\"https:\/\/www.shinkosha.com\/english\/wp-content\/uploads\/sites\/2\/2024\/04\/\u5358\u4f4d\u683c\u5b50-300x184.jpg 300w, https:\/\/www.shinkosha.com\/english\/wp-content\/uploads\/sites\/2\/2024\/04\/\u5358\u4f4d\u683c\u5b50.jpg 391w\" sizes=\"auto, (max-width: 300px) 100vw, 300px\" \/><\/a><\/p>\n<p style=\"text-align: center\"><span style=\"font-size: 12pt\">Unit cell of SrTiO<span style=\"font-size: 8pt\">3<\/span><\/span><\/p>\n<p>&nbsp;<\/p>\n<p>&nbsp;<\/p>\n<p>&nbsp;<\/p>\n","protected":false},"excerpt":{"rendered":"<p>\u3000SrTiO3 is a perovskite-type crystal consisting of SrO and TiO2 layers stacked in sequence and has a cubic crystal structure at room temperature.
