Other InformationHide

Thermal Behaviour:
In a thermogram over the range 654–1081°С, H2O is released with a endothermic effect. Over the range 900–1183°C, the main endothermic effect is caused by water and, possibly, F release, as well as melting of the mineral (1020°C).
Health Risks:
No information on health risks for this material has been entered into the database. You should always treat mineral specimens with care.
