A method was developed to solve the problems of long periods (&gt;0.5\u2009h) and ultrahigh temperature (1800\u00b0C) in tests. The sensor adopted here had good sound transmission performance as well as the high thermal conductivity of sapphire single crystals (Al<jats:sub>2<\/jats:sub>O<jats:sub>3<\/jats:sub>), as ultrasonic waveguides. The ultrasonic waveguide was produced by the method of the laser-heated pedestal growth (LHPG method). Calibration experiments in a high temperature furnace found that, at high temperatures and long exposure, sapphire ultrasonic temperature sensors had good stability and repeatability, and it survived in 1600\u00b0C for 360\u2009min. This sapphire ultrasonic temperature sensor has potential for applications in aircraft engines where monitoring of high temperatures is very important.<\/jats:p>","DOI":"10.1155\/2017\/9710763","type":"journal-article","created":{"date-parts":[[2017,12,14]],"date-time":"2017-12-14T18:37:46Z","timestamp":1513276666000},"page":"1-7","source":"Crossref","is-referenced-by-count":14,"title":["Research
