Ammonium Salt Preparation TRIZ Cases
- Boron Catalyst Dinitrogen Reduction Ammonia Production
A boron-based compound activates dinitrogen under mild conditions to produce ammoniacal nitrogen via hydrolysis.
- Scheelite Leaching with Mixed Acids and Closed-Circuit Recycling
Mixed acid leaching at low temperatures recovers tungstate while closed-circuit recycling prevents hazardous waste generation.
