Physical and Chemical Properties

Appearance

White or yellow silky odorless crystals.

Solubility in water

Soluble

Density

3.5 g/cm3

Usage

To make other zirconium compound, to precipitate acid dyes, to prepare high quality pigment toners, to improve properties of color lakes, has been used in prepn of body deodorants and antiperspirant preparations.

First Aid Measures

Ingestion

Give large amount of water.

Inhalation

Move to fresh air.

Skin

Flush with water.

Eyes

Irrigate exposed eyes with copious amounts of tepid water for at least 15 minutes. If irritation, pain, swelling, lacrimation, or photophobia persist, the patient should be seen in a health care facility.

Handling and Storage

Storage

Keep in a cool, dry, dark location in a tightly sealed container or cylinder. Keep away from incompatible materials, ignition sources and untrained individuals. Secure and label area. Protect containers/cylinders from physical damage.

Handling

All chemicals should be considered hazardous. Avoid direct physical contact. Use appropriate, approved safety equipment. Untrained individuals should not handle this chemical or its container. Handling should occur in a chemical fume hood.

Hazards Identification

Inhalation

Pulmonary abnormalities have not been demonstrated in workers with zirconium fume exposure for 1 to 5 years.

Skin

Dermal exposure to zirconium in topical poison ivy medications and deodorants has caused subcutaneous granulomas, probably due to a hypersensitivity reaction.

Ingestion

Ingestion of certain zirconium salts may cause irritant or caustic effects.

Exposure Controls/Personal Protection

Personal Protection

Clothing contaminated with zirconium oxychloride, zirconyl acetate, or zirconium tetrachloride should be placed in closed containers for storage until it can be discarded or until provision is made for the removal of containment from the clothing.

Respirators

Use NIOSH/MSHA approved respirator appropriate for exposure of concern.

Exposure Effects

Experimental animals exposed to massive doses have developed CNS depression. Two individuals administered 50 milligrams of zirconium malate intravenously developed vertigo. Small fractions of zirconium were absorbed in female rats by the oral route, and the metal seemed to concentrate in the ovaries and produce hypervascularization. <br>In mice, offspring of clams who received zirconium during pregnancy had long-lasting behavioral changes. <br>Zirconium is found in newborn rats. <br>In rats, zirconium appears in the breast milk.

Exposure limit(s)

IDHL: 500 mg/m3

Poison Class

4

Fire Fighting Measures

Fire Fighting

Use appropriate media to fight supporting fire. Contain runoff.

Accidental Release Measures

Small spills/leaks

Evacuate area and ventilate. Wear protective equipment. If required, use an inert absrobent. Sweep up and place in an appropriate container for disposal. Wash contaminated surfaces.

Stability and Reactivity

Stability

No data.

Incompatibilities

Reacts as acid to neutralize bases.
