| 摘要 |
The invention relates to chemistry, namely to processes for preparation of materials of multifunctional purpose, which can be used in medicine, instrument making, optoelectronics, ecology. The process for the preparation of fluoroapatite comprises the preparation of furnace charge by mixing of mixture of sodium metaphosphate, calcium fluoride and calcium carbonate, its further mixing with the melt of NaCl-KCl, heat treatment of the obtained mixture in mass ratio of furnace charge:melt, equal to 1.65:1, in the following ratio of the mentioned components in furnace charge, mass %, heat treatment of the obtained mixture in the open air at 680-700 °C and separation of base product. The use of the invention allows increasing the process efficiency and material quality. |
