Useful:

• Chemical Classes: Other Classes -> Salts, Basic
• Canonical SMILES: [NH4+].OP(=O)(O)[O-]
• Chemical Composition: Ammonium dihydrogen phosphate (ADP) is the ammonium salt of phosphoric acid (molar ratio 1:1). 2. Role: It serves as a fertilizer.
• Surface Modification: Surface modification of ADP with methyl hydrogen-containing silicone oil results in Modified Ammonium Dihydrogen Phosphate (MADP) powder, aimed at reducing the risk of coal dust explosion and promoting safety in coal chemical industries.
• Explosion Suppression: ADP, particularly when modified, has sound gas explosion suppression effects.
• Moisture Absorption: ADP-based explosion-suppressing powders are prone to absorbing moisture from the air, which can affect their dispersion and spraying performance, leading to poor explosion suppression effects.
• Nonlinear Optics: ADP is crucial in nonlinear optics and finds applications in fabricating various optical devices such as frequency conversion, frequency mixing, microscopic lasing, telecommunication, optical parametric, optical switching, and optical data storage devices.
• Characteristics: ADP crystal exhibits characteristics such as ferroelectricity, piezoelectricity, high optical homogeneity, low cutoff wavelength, high second harmonic generation (SHG) coefficient, and strong thermal and physical stability.
• Research Methods: ADP crystals have been grown using various techniques including slow evaporation (rotational, unidirectional, self-nucleation), gel growth, and slow cooling growth techniques.
