Thermal Behaviour:

When heated at 750 C, most of the mineral volatilizes leaving a small yellow residue giving the x-ray pattern of U3O8.

Notes:

Dissolves with difficulty in concentrated HCl on prolonged heating. Dissolves in concentrated HNO3 with separation of molybdic acid. Is insoluble in H2SO4 or 10% KOH. Dissolves in 2O% Na2CO3 solution on heating.

Radioactive.

Health Risks:

No information on health risks for this material has been entered into the database. You should always treat mineral specimens with care.
