The design, operation and problems in the reaction section in the phosphoric acid facility are introduced. The problems lie in the poor crystal of phosphogypsum and low P2O5 recovery of 83.17%.
After deformation and heat treatment, single crystal al wire will generate a mass of dislocation cells, high density dislocations and evident recovery phenomena.
单晶铝线材在变形和加热后会产生大量的位错胞、高密度位错和明显的回复再结晶现象。
