Nd-doped uncooled infrared detector and preparation method of nickelate ceramic for magnetic sensitivity
The invention discloses an Nd-doped uncooled infrared detector and a preparation method of nickelate ceramic for magnetic sensitivity, and relates to the technical field of functional ceramic preparation. The method comprises the following stages: solution preparation, a wet gel process, a dry gel process, a calcination process, a powder pressing process and a secondary calcination process. A series of nickelate ceramic targets which are high in density, good in crystallization quality, short in preparation period and excellent in performance are prepared through a sol-gel method, and the application conditions of non-refrigeration and low noise are achieved; the material has the characteristics of no toxicity, no pollution, high sensitivity and low room temperature resistivity, and can be used as a candidate material for developing an uncooled infrared detector and a magnetic sensitive device along military and high-end devices with higher possibility.
