| Molecular Formula | 3Ca3(PO4)2Ca(F、Cl)2.Sb.Mn |
| Physical and Chemical Properties | Chemical properties white powder. |
| Use | Applications for white fluorescent lamps, as fluorescent materials. For the manufacture of fluorescent tubes |
its technological process can be generally divided into raw material preparation, purification, batching, burning, post-treatment and other processes.
In order to make high-quality fluorescent materials, strict attention must be paid to the purity of raw materials. The following table shows the purity requirements of the main raw materials for preparing calcium halophosphate phosphors.
When preparing the mixture, the amount of each raw material must first be calculated theoretically according to the apatite composition. The ratio of the sum of the moles of calcium and manganese to the moles of phosphorus in phosphate should be 5:3. The actual use is about 4.9:3. Then weigh, mix, grind fine with a ball mill, sift, and then under nitrogen, at a constant temperature sintering at about 1150 ℃ for a certain period of time, take out and cool, select under an ultraviolet lamp, and then grind fine and sift, surface treatment, Dry and sift to obtain the finished product of halogenated calcium phosphate phosphor.
