תיאור המוצר:

נכסים ו נוֹהָג:

Cerium ammonium nitrate (CAS 16774-21-3) is mainly composed of cerium (Ce), ammonia (NH₄⁺) and nitrate (NO₃⁻). It has high redox activity and is used in catalysis, environmental protection, materials science and other fields.

1. שדה זרז

Cerium ammonium nitrate is widely used in catalysts, especially in automobile exhaust treatment catalysts, to reduce the emission of harmful gases (such as carbon monoxide, nitrogen oxides and hydrocarbons). In addition, it is also widely used in oxidation reactions and desulfurization catalytic reactions to improve reaction efficiency.

2. Environmental protection and water treatment

As a strong oxidant, cerium ammonium nitrate can remove organic pollutants and heavy metals in water to ensure water quality safety.

3. Surface treatment and material synthesis

In metal surface treatment, cerium ammonium nitrate can improve the corrosion resistance and oxidation resistance of metal materials (such as aluminum and steel).

4. Chemical analysis and laboratory application

Cerium ammonium nitrate can be used as an analytical reagent for redox titration and microanalysis. Especially in chromatography and spectral analysis, ammonium cerium nitrate helps to accurately detect and analyze chemical components.

5. אגירת אנרגיה

In batteries and supercapacitors, ammonium cerium nitrate is used as a catalyst material to help improve the efficiency and performance of energy storage devices.

6. תעשייה גרעינית

Because cerium is radioactive, ammonium cerium nitrate is used in the nuclear industry as a neutron absorber in nuclear reactors to regulate the reaction rate and stability of the reactor.

תנאי אחסון: It should be stored in a cool, dry, well-ventilated place, avoiding high temperature and humidity to prevent decomposition and hydrolysis.
