НИТРАТ ЦИРКОНИЯ (ЦИРКОНИЛ)

Description

Zirconium nitrate (zirconyl), Zr(NO3)4 is an inorganic zirconium(IV) salt, an anhydrous form of zirconium tetranitrate from the class of oxidizing transition metal nitrates. The high polar surface area value (PSA 275.52) reflects the presence of four nitrate groups in the molecule. The name “zirconil” in the product nomenclature is often used collectively for a number of oxo- and nitrate-containing zirconium salts, therefore, when ordering, it is important to check the CAS number and the formula of a specific item.

Scope of application

It is used as a zirconium precursor in catalysis and ceramic production, an oxidizing agent and a reagent for the production of other zirconium compounds, including hydrated and oxynitrate forms (certain catalog items, CAS 14985-18-3 and CAS 13826-66-9).

• precursor for the production of zirconium dioxide and ceramic powders
• catalysts and co-catalysts based on zirconium
• oxidizing reagent in inorganic synthesis
• raw materials for the production of other zirconium nitrate and oxynitrate compounds
• analytical chemistry - source of soluble zirconium for precipitation

Advantages

The supplier's passport for this catalog item contains a minimum set of parameters (molecular weight, exact weight, PSA, XLogP3, density); the absence of a block of hazard codes does not mean that the substance does not have the oxidizing properties characteristic of the class of transition metal nitrates - when handling, it is recommended to be guided by the data on related compounds (zirconyl nitrate hydrate, CAS 14985-18-3, and zirconium oxynitrate, CAS 13826-66-9). The high PSA value (275.52)—one of the highest of the zirconium compounds considered—indicates strong polarity and therefore good expected solubility of the salt in water.

Storage and transportation conditions

Store in an airtight container in a cool, dry place, away from flammable materials, reducing agents, sulfur and phosphorus, since zirconium nitrates are generally oxidizing substances. If there are no specific transport codes for a particular shipment in the passport, check the classification with the supplier before transportation. General precautions for oxidizing metal nitrates include avoiding contact with organic solvents and reducing agents.

Delivery form and quality

Molecular weight 339.244 (exact weight 337.856) and density 1.4 are given by the supplier as basic batch parameters; detailed data on melting points, boiling points and toxicity for this specific product item are not available in the dump. HS code 2834299090, common with a number of other inorganic nitrates, is used for customs clearance of the consignment. When choosing between this anhydrous form and the related hydrated zirconium nitrates, the deciding factor is usually the required ratio of zirconium to reactant mass in the target reaction.
