Fluorescence of YecoraiteHide

Other InformationHide

Notes:
The mineral fuses easily to a red glass and begins to evolve TeO2 shortly after the loss of water. It is readily
soluble in cold 16% HCl or 10% HNO3
Health Risks:
No information on health risks for this material has been entered into the database. You should always treat mineral specimens with care.
