Abstract

The invention relates to zirconia single-crystal optical fibers as well as a preparation method and application thereof. The crystal molecular formula is ZrO2; the ZrO2 single-crystal optical fibers are fibrous ZrO2 single crystals having a great aspect ratio and have the advantages of ZrO2 single-crystal fibers and ZrO2 polycrystalline fibers at the same time. The zirconia single-crystal opticalfibers have a diameter range of 0.5-1mm and the length of greater than 15cm. The ZrO2 single-crystal fibers grow by means of laser heated pedestal growth (LHPG). The melting point of the zirconia single-crystal optical fibers reaches up to 2715 DEG C. Compared with the prior art, the zirconia single-crystal optical fibers have the excellent physical and chemical properties such as high thermal conductivity, high hardness, high strength, high toughness and very high wear resistance and chemical corrosion resistance, and can used for manufacturing novel high temperature sensors.

Description

technical field

[0001] The invention relates to a novel single crystal optical fiber and its preparation method and application, in particular to a zirconia single crystal optical fiber and its preparation method and application, belonging to the technical field of crystals and devices. Background technique

[0002] High temperature sensors are mainly used in many fields such as aerospace, weapon manufacturing, nuclear industry, metallurgy, chemical industry, heat treatment, etc., and can measure high temperatures of thousands of degrees. At present, high-temperature thermocouples and tungsten-rhenium thermocouples are generally used in contact high-temperature tests at home and abroad, which basically meet the needs of the medium and low temperature fields. However, with the deepening of research technology, it is necessary to measure the combustion chamber temperature, especially some special combustion fields, such as rocket and missile gas jet temperature, scramjet combu...
