Product Description

Ammonia (NH₃) Product Introduction

1. Product Overview

Ammonia (NH₃) is a colorless gas with a pungent, suffocating odor. It is composed of one nitrogen atom and three hydrogen atoms, with a molecular weight of 17.03 g/mol. As a key industrial chemical, ammonia plays a critical role in various sectors including agriculture, manufacturing, and environmental protection.

With a density of 0.771 g/L at standard conditions (about 0.597 times that of air), ammonia is lighter than air and tends to rise when released. It is highly soluble in water, with one volume of water capable of dissolving approximately 700 volumes of ammonia gas at room temperature and pressure, forming ammonium hydroxide solution.

3. Key Chemical Characteristics

Solubility

Ammonia is extremely soluble in water, forming ammonium hydroxide solution which is weakly alkaline. The dissolution process is exothermic, and the solution readily releases ammonia gas when heated.

Reactivity

Basicity: Ammonia acts as a weak base, reacting with acids to form ammonium salts
Redox Properties: Ammonia exhibits reducing properties at high temperatures, decomposing into nitrogen and hydrogen
Complex Formation: Ammonia can act as a ligand to form coordination complexes with metal ions

Hazardous Properties

Flammability: Ammonia is flammable within the range of 15.5%-28% in air
Corrosiveness: Ammonia is corrosive to skin, eyes, and respiratory tract
Toxicity: Inhalation of high concentrations can cause respiratory irritation and even death

4. Applications

Agriculture

Fertilizer Production: Approximately 80% of global ammonia production is used for manufacturing nitrogen fertilizers such as urea, ammonium nitrate, and ammonium sulfate
Direct Application: Anhydrous ammonia is directly injected into soil as a nitrogen source for crops

Industrial Manufacturing

Chemical Synthesis: Used as a raw material for producing nitric acid, urea, and other chemicals
Refrigeration: Liquid ammonia is widely used as a refrigerant in industrial cooling systems
Plastics and Fibers: Used in the production of polyamides (nylon) and other synthetic materials
Water Treatment: Used in wastewater treatment processes for pH adjustment and ammonia stripping

Electronic Industry

Semiconductor Manufacturing: High-purity ammonia is used in the production of semiconductors and electronic components
LED Production: Used in the manufacturing of gallium nitride (GaN) for LED production

Energy and Environmental Protection

Flue Gas Denitrification: Used as a reducing agent in selective catalytic reduction (SCR) systems to reduce nitrogen oxide emissions
Hydrogen Storage: Ammonia is being researched as a potential hydrogen storage medium for energy applications

5. Safety and Handling
