提高卤磷酸钙荧光粉抗光衰性能的有效方法

The method of improving the antioptica weaken of calcium chloro-phosphate fluoresence powder

为了提高卤磷酸钙荧光粉抗光衰性能,在荧光粉成品水洗或酸洗过程中添加微量Sb_2O_3,经一系列试验及试生产,发现能有效地提高卤磷酸钙荧光粉抗光衰性能。

In order to improve the antioptica weaken of calcium chloro-phosphate fluorescence powder, add little Sb2O3 to fluorescence powder, going through a lot of experiments and test productions, we find that it can improve the antioptica weaken of calcium chloro-phosphate fluorescence powder. At present the technology is the advanced level in our country.
