Method for densifying fluorescent powder and yttrium oxide ceramic at room temperature
The invention discloses a method for densifying fluorescent powder and yttrium oxide ceramic at room temperature, and belongs to the technical field of preparation and application of fluorescent powder ceramic materials. Through fine ball milling and two times of cold isostatic pressing, deionized water is added before the second time of cold isostatic pressing, so that commercial fluorescent powder and yttrium oxide are densified at room temperature. The relative density of the prepared fluorescent powder ceramic reaches 53-58% at room temperature, and the luminescence of the fluorescent powder is not influenced. The preparation method provided by the invention is simple in process, stable in product performance and suitable for industrial production.
一种室温下荧光粉与氧化钇陶瓷致密化的方法，属于荧光粉陶瓷材料制备应用技术领域。通过精细的球磨和两次冷等静压，在第二次冷等静压前加入了去离子水，来实现室温下将商业荧光粉体与氧化钇的致密。制备的荧光粉陶瓷在室温下其相对密度达到53~58%，且对荧光粉的发光没有影响。本发明提供的制备方法工艺简单，产品性能稳定，适合工业化生产。
