Description
Zirconium(IV) nitrate, also known as zirconyl nitrate, is a white crystalline solid with the chemical formula Zr(NO3)4. It is a very hygroscopic compound, meaning it readily absorbs moisture from the environment. Zirconium(IV) nitrate has a refractive index of 1.60 and is highly soluble in water, resulting in an acidic aqueous solution. It is also soluble in alcohol and is noncombustible. However, it can accelerate the burning of combustible materials and may cause an explosion if exposed to large quantities of heat or fire. Toxic oxides of nitrogen are produced when Zirconium(IV) nitrate is involved in fires.
Uses
1. Used in Chemical Industry:
Zirconium(IV) nitrate is used as a preservative due to its ability to absorb moisture and maintain an acidic environment, which helps prevent the growth of microorganisms.
2. Used in Analytical Chemistry:
Zirconium(IV) nitrate serves as an analytical standard for zirconium, allowing for accurate measurements and analysis of zirconium content in various samples.
3. Used in Manufacturing Zirconium Salts:
Zirconium(IV) nitrate is a key component in the production of various zirconium salts, which have applications in different industries, such as ceramics, catalysts, and refractory materials.
4. Used in Fire Safety:
Although Zirconium(IV) nitrate can accelerate the burning of combustible materials, it is noncombustible itself. This property can be utilized in fire safety applications to control the spread of fire in certain situations.
5. Used in Research and Development:
Zirconium(IV) nitrate's unique chemical and physical properties make it a valuable compound for research and development in various fields, including materials science, pharmaceuticals, and environmental science.
Preparation
Zirconium nitrate is prepared by reacting nitric acid with zirconium oxide:
ZrO2 + 4HNO3 → Zr(NO3)4 + 2H2O
The compound is crystallized as pentahydrate following evaporation to dryness.
Reactivity Profile
Mixtures of metal/nonmetal nitrates, such as Zirconium(IV) nitrate, with alkyl esters may explode owing to the formation of alkyl nitrates; mixtures a nitrate with phosphorus, tin (II) chloride, or other reducing agents may react explosively [Bretherick 1979. p. 108-109]. Dissolves in water to give an acid solution.
Health Hazard
Has only a mild pharmacological action. Inhalation of dust may irritate nose and throat. Contact with eyes or skin causes irritation.
Safety Profile
Moderately toxic by
inhalation and ingestion. A powerful
oxiQzer. When heated to decomposition it
emits toxic fumes of NOx. See also

Check Digit Verification of cas no
The CAS Registry Mumber 13746-89-9 includes 8 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 5 digits, 1,3,7,4 and 6 respectively; the second part has 2 digits, 8 and 9 respectively.
Calculate Digit Verification of CAS Registry Number 13746-89:
(7*1)+(6*3)+(5*7)+(4*4)+(3*6)+(2*8)+(1*9)=119
119 % 10 = 9
So 13746-89-9 is a valid CAS Registry Number.
