| Hazard Information | Back Directory | [Potential Exposure]
Sodium aluminum fluoride is used in making pesticides, ceramics, glass, and polishes; in refining reduction of aluminum, flux, glass, and enamel. | [First aid]
If this chemical gets into the eyes, remove any contact lenses at once and irrigate immediately for at least 15 minutes, occasionally lifting upper and lower lids. Seek medical attention immediately. If this chemical contacts the skin, remove contaminated clothing and wash immediately with soap and water. Speed in removing material from skin is of extreme importance. Seek medical attention immediately. If this chemical has been inhaled, remove from exposure, begin rescue breathing (using universal precautions, including resuscitation mask) if breathing has stopped and CPR if heart action has stopped. Transfer promptly to a medical facility. When this chemical has been swallowed, get medical attention. If victim is conscious, administer water, or milk. Do not induce vomiting. Medical observation is recommended for 24 to 48 hours after breathing overexposure, as pulmonary edema may be delayed. As first aid for pulmonary edema, a doctor or authorized paramedic may consider administering a drug or other inhalation therapy. | [Shipping]
UN3077 Environmentally hazardous substances, solid, n.o.s., Hazard class: 9; Labels: 9-Miscellaneous hazardous material, Technical Name Required. | [Incompatibilities]
Incompatible with strong acids such as sulfuric, strong oxidizers, hydrogen fluoride. | [Chemical Properties]
Sodium aluminum fluoride is a snow-white crystalline solid, powder or vitreous mass. The crystalline solid (natural product (cryolite) may be colored reddish or brown or even black but loses this discoloration on heating); synthetic product is an amorphous powder. Odorless | [Waste Disposal]
In accordance with 40CFR 165 recommendations for the disposal of pesticides and pesticide containers. Must be disposed properly by following package label directions or by contacting your local or federal environmental control agency, or by contacting your regional EPA office. | [Uses]
Sodium aluminum hexafluoride is used as a solvent (or flux) for electrolysis aluminum oxides such as bauxite, whitener for enamels and an opacifier for glass and in the industrial production of aluminum. | [Application]
Recycling and treatment of fluorine-containing waste are required for
environmental protection and to utilize the fluorine resources. Because
of decreases in fluorite reserves and inefficient fluorine resource
recovery, cryolite has become a potential resource for fluorine
recovery[1]. | [Definition]
A compound found in large
quantities in South Greenland. It is white
or colorless, but may be reddish or brown
because of impurities. Sodium hexafluoroaluminate is used as a flux in the manufacture of aluminum. It crystallizes in the
monoclinic system but in forms that closely
resemble cubes and isometric octahedrals. | [References]
