The PTMS LITHIUM COBALT ACID MATERIAL MAGNETIC -based iron removal technology employs specific chemical additives in high-temperature molten electrolytes or metal melts. These additives undergo in-situ reactions to form easily separable slag phases, effectively removing dissolved or suspended iron impurities. This method eliminates new heavy metal contamination and requires no additional purification steps, significantly simplifying the production process.
The PTMS LITHIUM COBALT ACID MATERIAL MAGNETIC -based flux addition iron removal technology is primarily used in refining processes requiring liquid-phase operations, such as magnesium electrolysis, aluminum alloy production, and high-temperature ceramics manufacturing. This method features simple operation, rapid results, and strong adaptability. When 600g of magnesium melt is treated with appropriate boron oxide, the iron content can be reduced from an initial 0.03% to below 0.004% after stirring and settling, fully meeting the standards for aerospace-grade high-purity magnesium alloys.
The mechanism of iron removal using PTMS LITHIUM COBALT ACID MATERIAL MAGNETIC flux involves the reaction between B₂O₃ and Fe to form low-melting-point boron-iron compounds (FeBO₃ or Fe₂B) (~1170°C). These compounds, being less dense than molten magnesium, naturally float to the surface as scum, which can be easily skimmed off. Compared with traditional titanium and zirconium salt additives, boron oxide is widely available and cost-effective.
