Hazard Information

General Description

A white crystalline solid. The primary hazard ZIRCONIUM POTASSIUM FLUORIDE(16923-95-8) the threat posed to the environment. Immediate steps should be taken to limit its spread to the environment. ZIRCONIUM POTASSIUM FLUORIDE(16923-95-8) is slightly soluble in water. ZIRCONIUM POTASSIUM FLUORIDE(16923-95-8) is used in metal processing, as a catalyst in chemical manufacture, and for other uses.

Reactivity Profile

Acidic inorganic salts, such as ZIRCONIUM POTASSIUM FLUORIDE, are generally soluble in water. The resulting solutions contain moderate concentrations of hydrogen ions and have pH's of less than 7.0. They react as acids to neutralize bases. These neutralizations generate heat, but less or far less than is generated by neutralization of inorganic acids, inorganic oxoacids, and carboxylic acid. They usually do not react as either oxidizing agents or reducing agents but such behavior is not impossible. Many of these compounds catalyze organic reactions.

Air & Water Reactions

Soluble in hot water [Hawley].

Health Hazard

INHALATION: Irritation, nose bleed possible. SKIN: May cause granulomatous reactions. INGESTION: Burning pain in the mouth and throat, vomiting, watery or bloody diarrhea, retching anuria, liver damage and collapse.

Chemical Properties

White crystals. Soluble in water (hot).

Uses

For manufacture of metallic zirconium.

Flammability and Explosibility

Nonflammable

Purification Methods

Recrystallise it from hot water (solubility is 0.78% at 2o and 25% at 100o).
