Pressure sensor ceramic material and preparation method thereof
The invention provides a pressure sensor ceramic material and a preparation method thereof, the pressure sensor ceramic material comprises the following components: nano ceramic particles with a molecular formula of CaCu3-xMxTi4-yScyO12, wherein 0 < x < = 1, 0.2 < = y < = 0.8; glass-phase nano-oxide particles with the molecular formula being B2O3; AlN; BeO; a polymethylformamide; polycrystalline diamond micro powder; a microfiltration membrane polymer; and dimethyl formamide. According to the preparation method disclosed by the invention, by preparing the diamond micro powder plated with the AlN and BeO submicron layer with the thickness of 10-20 mu m, the defects of uniform crystal structure and isotropy caused by gradient modification of CaCu3-xMxTi4-yScyO12 by the B2O3 glass phase nanoparticles are reduced, so that the stress concentration of the finally prepared ceramic material against impact is effectively reduced, and the impact resistance of the ceramic material is improved. Thus, the defect that the section combination degree is reduced due to grain boundary movement is avoided.
本发明提供一种压力传感器陶瓷材料及其制备方法，包括以下成分：分子式为CaCu3‑xMxTi4‑yScyO12的纳米陶瓷颗粒，其中0＜x≤1，0.2≤y≤0.8；分子式为B2O3的玻璃相纳米氧化物颗粒；AlN；BeO；聚甲基甲酰胺；多晶金刚石微粉；微滤膜聚合物；二甲基甲酰胺。本发明通过制备得到镀覆有10μm～20μm的AlN和BeO亚微米层的金刚石微粉，降低由于B2O3玻璃相纳米颗粒对CaCu3‑xMxTi4‑yScyO12进行梯度改性所带来的晶体结构均匀、各向同性的缺陷，进而有效降低了最终制备得到的所述陶瓷材料对抗冲击的应力集中，避免了晶界移动所带来的截面结合程度降低的缺陷。
