Technical barriers to battery-grade monoammonium phosphate

Is China's ammonium phosphate capacity too high?

China's traditional ammonium phosphate capacity is seriously excess. We should promote the deep integration of the industry, and proceed with capacity elimination to guide a healthy and long-term development of the phosphate industry, to ensure the long-term supply of phosphorus resources in China.

How to neutralize dilute phosphoric acid and concentrate ammonium phosphate slurry?

The key of this process is to neutralize dilute phosphoric acid first, and then concentrate ammonium phosphate slurry. It adopts external circulation ammoniation reactor and the “integration of neutralization and concentration” technology in the neutralization and concentration of slurry process , , .

Can phosphate fertilizer be produced by slurry map technology?

After more than 60 years of development, China’s ammonium phosphate fertilizer industry has experienced the road of from scratch and from weak to strong. The successful development of the slurry MAP technology ended the history that the high concentration phosphate fertilizer cannot be produced by using the medium and low grade phosphate ore.

What is ammonium polyphosphate?

Ammonium polyphosphates (APP) can be grouped into an inorganic polymer with P-O-P alternating structure. As a downstream product of the phosphate industry, APP with different crystal forms contribute in various fields .

What are the different types of ammonium phosphate products?

At present, there are a variety of products, such as slurry monoammonium phosphate (MAP), diammonium phosphate (DAP), industrial grade MAP, water soluble MAP, water soluble ammonium polyphosphate (APP) and so on.
