that these particles are good crystal zinc blende with average size of 50 nm, and these particles also possess good IR transmittance in the range from 400 to 4 000 cm-1 and good thermal stability in oxygen. Key words: ultrasonic; ZnO; nano-ZnS; crystal 纳米科技是20世纪80年代末期以来迅速崛起的新科技,纳米结构的微粒以其独特的物理......
makes it easy to spread to the particle surface and its internal reaction and promote dephosphorization. In addition, the particle morphology and crystal structure are destroyed, and the particles are in metastable state, which further promotes the dephosphorization. Key words: high concentrate phosphorus rough iron ore; mechanical activation; selective dissociation; particle morphology; sulfuric......
