Latest Patents

Zhan Xu's latest patents include a method for recovering rare earth elements from NdFeB waste and the use of ferric oxide as a raw material for manganese-zinc ferrite. The first patent describes a molten salt system that comprises 40% KAlF or NaAlF, 40% KBeF, and 20% KAlF. This innovative system achieves recovery rates of rare earth elements exceeding 98%, while operating at extraction temperatures 100-400° C. lower than current methods. The extraction time is also significantly reduced to just 1-3 hours, leading to remarkable economic benefits and lower energy consumption.

The second patent outlines a method for preparing a soft magnetic manganese-zinc ferrite composite by systematically removing impurities from industrial waste. This process involves crushing and drying manganese-containing waste, mixing it with a flux, and roasting it in a muffle furnace. Multi-step impurity removal results in high-purity solutions of manganese and zinc sulfates, which are then combined to produce the desired manganese-zinc ferrite composite.
