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). |

| 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. |

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.
