Composite ceramic as well as preparation method and application thereof
The invention provides composite ceramic as well as a preparation method and application thereof. The composite ceramic provided by the invention comprises a SiBCN matrix and a doping phase, and the doping phase comprises Ti3AlC2. The composite ceramic material taking SiBCN as a matrix is prepared by doping a second phase Ti3AlC2, and the material greatly improves the cycling stability of the resistivity of single-phase PDC-SiBCN in an extreme environment while retaining the original high-temperature sensing performance, so that the resistivity of the single-phase PDC-SiBCN in the extreme environment is greatly improved. The composite ceramic material with high cycle stability can be cyclically used for a long time at the heating rate of 100 DEG C/min in an air environment at the highest temperature of 1200 DEG C, and has an application prospect as an extreme environment high-temperature sensor. The invention also provides a preparation method and application of the composite ceramic.
本发明提供了一种复合陶瓷及其制备方法和应用。本发明的复合陶瓷，包括SiBCN基体和掺杂相，所述掺杂相包括Ti3AlC2。通过掺入第二相Ti3AlC2，制备了一种以SiBCN为基体的复合陶瓷材料，该材料在保留原有高温传感性能的同时，极大地改善了单相PDC‑SiBCN在极端环境中电阻率的循环稳定性，得到一种可以在最高达1200℃的空气环境中、以100℃/min升温速率长时间循环服役的高循环稳定性复合陶瓷材料，具有作为极端环境高温传感器的应用前景。本发明还提供了复合陶瓷的制备方法和应用。
