UO2(OH)2 or (UO2)2(OH)2

 

Uranyl hydroxide is a hydroxide of uranium with the
chemical formula UO2(OH)2 in the monomeric form and
(UO2)2(OH)2 in the dimeric; both isomers
may exist in normal aqueous media. Uranyl hydroxide hydrate is precipitated
as a collodial yellowcake from oxidized uranium liquors near neutral pH.Uranyl hydroxide was once used in glassmaking and ceramics in the
colouring of the vitreous phases and the preparation of pigments for high
temperature firing. The introduction of alkaline diuranates into glasses
leads to yellow by transmission, green by reflection; moreover these glasses
become dichroic and flourescent under ultraviolet rays. The material
conducts protons and when pressed under steadily increasing pressure
(subsequently gradually released) and may find use as a fuel cell
component. (United States Patent 4179491)

Uranyl hydroxide is teratogenic and radioactive, and should be handled with the appropriate care.

Hazards and Protection.
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.
Protection Wear appropriate protective gloves, clothing and goggles.
Respirators Wear positive pressure self-contained breathing apparatus (SCBA).
Small spills/leaks Do not touch damaged packages or spilled material. Cover liquid spill
with sand, earth or other noncombustible absorbent material. Cover powder
spill with plastic sheet or tarp to minimize spreading. Contact radiation
safety officer.
Stability No data.
Fire.
Firefighting Presence of radioactive material will not influence the fire
control processes and should not influence selection of techniques. Small
Fires: Dry chemical, carbon dioxide, water spray or regular foam. Large
Fires: Water spray, fog (flooding amounts).
Fire potential May burn but does not ignite readily.
Health.
Exposure effects
   Ingestion See Inhalation.
   Inhalation Minimal risk if packaging remains intact. Package damage can result in a
measurable release of radiation but the risk is still low.
   Skin See Inhalation.
   Eyes See Inhalation.

First aid 

Ingestion

Medical problems take priority over radiological concerns. Use first aid
treatment according to the nature of the injury. Do not delay care and
transport of a seriously injured person.

Inhalation

Apply artificial respiration if victim is not breathing. Administer
oxygen if breathing is difficult. See Ingestion.

Skin

Immediately flush with running water for at least 20 minutes. See
Ingestion.

Eyes

Immediately flush with running water for at least 20 minutes. See
Ingestion.
