Paramagnetic metal element doped structured SiOC ceramic as well as preparation method and application thereof
The invention discloses paramagnetic metal element doped structured SiOC ceramic as well as a preparation method and application thereof, and relates to the technical field of ceramic. The ceramic comprises SiOC ceramic with a negative Poisson's ratio structure, and paramagnetic metal elements are doped in the SiOC ceramic. The paramagnetic metal element comprises one or more of aluminum, magnesium, lithium, sodium, potassium, titanium, vanadium, niobium, zirconium, aluminum, iron, cobalt, nickel, hafnium, tantalum, tungsten and gadolinium. The conductivity of the SiOC ceramic is regulated and controlled by changing the concentration of the doped paramagnetic metal compound, the conductivity with the semiconductor level is obtained, the high piezoresistive coefficient is obtained, and therefore the pressure change can be well monitored. And the conductivity can be improved by hundreds of times or even thousands of times by regulating and controlling the doping concentration and the sintering process.
本发明公开了一种顺磁性金属元素掺杂的结构化SiOC陶瓷及其制备方法和应用，涉及陶瓷技术领域。所述陶瓷包括负泊松比结构的SiOC陶瓷，所述SiOC陶瓷中掺杂有顺磁性金属元素；所述顺磁性金属元素包括铝、镁、锂、钠、钾、钛、钒、铌、锆、铝、铁、钴、镍、铪、钽、钨、钆中的一种或多种。本发明通过改变掺杂的顺磁性金属化合物的浓度调控SiOC陶瓷的电导率，获得具有半导体水平的电导率，得到较高的压阻系数，从而能够很好的监测压力变化。通过调控掺杂浓度和烧结工艺可以将电导率提升上百倍甚至上千倍。
