Luminescent ceramic for high-temperature warning and preparation method thereof
The invention discloses luminescent ceramic for high-temperature warning and a preparation method of the luminescent ceramic. The chemical formula of the luminescent ceramic is Ba1-x-yEuxDyySi2-zGezO5, x is greater than or equal to 0.01 and less than or equal to 0.05, y is greater than or equal to 0.01 and less than or equal to 0.06, and z is greater than or equal to 0.2 and less than or equal to 0.5. Ba2CO3, SiO2, GeO2, Eu2O3 and Dy2O3 are used as raw materials, and are subjected to grinding, drying, secondary grinding and reduction sintering to obtain the fluorescent powder. The luminescent ceramic prepared by the invention only shows weak light under the low-temperature condition of 60 DEG C or below, but the brightness of the ceramic is obviously enhanced when the temperature rises to 60-120 DEG C, so that a warning effect in a specific temperature range is achieved; the weather resistance is good, and after continuous circulation for 2160 hours at the temperature from room temperature to 180 DEG C in a high and low temperature circulation test box, the brightness of the coating still can be kept 90% or above of the original brightness.
本发明公开了一种用于高温警示的发光陶瓷及其制备方法。所述发光陶瓷的化学式为Ba1‑x‑yEuxDyySi2‑zGezO5，其中0.01≤x≤0.05，0.01≤y≤0.06，0.2≤z≤0.5。以Ba2CO3、SiO2、GeO2、Eu2O3和Dy2O3作为原料，经研磨、干燥、二次研磨、还原烧结得到。本发明制备的发光陶瓷在60℃及以下的低温条件下仅呈现微弱的亮光，但随着温度升高到60～120℃的范围内时，陶瓷亮度会明显增强，从而达到在特定温度范围内警示的作用；耐候性能良好，在高低温循环试验箱中以室温至180℃的温度连续循环2160小时以后，其亮度仍然能够保持原亮度的90％以上。
