Lithium carbonate and lithium hydroxide are used as lithium sources, ferrous oxalate, ferrous oxalate, iron oxide and iron phosphate are used as iron sources, and phosphate roots mainly come from ammonium dihydrogen phosphate and so on. The typical PTMS LITHIUM COBALT ACID MATERIAL MAGNETIC process process is: the raw material ball is ground and dried, in Muffle furnace or tube furnace in inert or reducing atmosphere, with a certain temperature acceleration to heat to a certain temperature, reaction for a period of time after cooling.
The advantages of high temperature solid phase method is that the PTMS LITHIUM COBALT ACID MATERIAL MAGNETIC process is simple and easy to achieve industrialization, but the particle size of the product is not easy to control, uneven distribution, morphology is irregular, and the use of inert gas protection in the synthesis process. Spodumene concentrate and K2SO4 (or CaSO4 or a mixture of both) are mixed and sintered at a certain temperature, through a series of physical and chemical reactions.
The metal elements in the sulfate added will replace the LITHIUM in the ore to produce soluble sulfate, and the main impurities will produce water-insoluble compounds, and then the clinker after sintering leaching separation, lithium ions into the solution, after purification, concentration, precipitation, PTMS LITHIUM COBALT ACID MATERIAL Lithium carbonate product is obtained after MAGNETIC removal of iron.
