| Hazard Information | Back Directory | [Chemical Properties]
Rhodium, together with platinum, palladium,
iridium, ruthenium, and osmium, is one of the platinum-
group metals in Group VIII of the Periodic Table. Rhodium
metal is a white, hard, ductile, malleable solid with a
bluish-gray luster. | [Potential Exposure]
Rhodium has few applications by
itself, as in rhodium plating of white gold jewelry or plat-
ing of electrical parts, such as commutator slip rings, but,
mainly, rhodium is used as a component of platinum alloys.
Rhodium-containing catalysts have been proposed for use
in automotive catalytic converters for exhaust gas cleanup. | [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. Seek medical attention immediately.
If this chemical has been inhaled, remove from exposure,
begin rescue breathing (using universal precautions, includ-
ing 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 medi-
cal attention. Give large quantities of water and induce
vomiting. Do not make an unconscious person vomit. If
metal fume fever develops, it may last less than 36 hours.
| [Shipping]
Flammable powder, Hazard Class: 4.1; Labels:
4.1-Flammable solid. | [Incompatibilities]
Flammable as a dust, fume, or powder
may form explosive mixture with air. Incompatible with
strong oxidizers (chlorates, nitrates, peroxides, permanga-
nates, perchlorates, chlorine, bromine, fluorine, etc.); con-
tact may cause fires or explosions. Keep away from
alkaline materials, strong bases, strong acids, oxoacids,
epoxides, bromine pentafluoride, and bromine trifluoride;
chlorine trifluoride; oxygen difluoride. | [Waste Disposal]
Recovery in view of the high
economic value. Recovery techniques for recycling of
rhodium in plating wastes and spent catalysts have been
described in the literature. |
