Mar 16, 2021· When steel or iron parts are placed in the phosphoric acid, this causes the metal to react in a way that locally depletes the hydronium (H 3 O +) ions, raises the pH and causes the dissolved salt to fall out of the solution and precipitate onto the surface. The acid and metal reaction also creates iron phosphate, which may be deposited.

Phosphoric acid is a crude product and therefore the varieties are legion. Generally, stainless steel tanks found in chemical tankers are resistant to phosphoric acid attack; however, excessive fluoride within the phosphoric acid can initiate corrosion attacks allowing for continuation of the attack by the phosphoric acid itself.
The case of phosphate– As much as for iron, or energy-intensive cement units, the essential input is natural gas having to make arbitrage between the transfer price on the international market and the transfer to the units to generate a high added value.So the cost price of a tonne of ammonia at 4 Dollars/mmBTU would be 114 Euros per tonne, and on the contrary at 7 Dollars, we will have 200 ...
