Other InformationHide

Electrical:
Some samples are piezoelectric.
Thermal Behaviour:
Before the blowpipe, melts easily to a brown transparent bead.
At 1000 °C, batisite decomposes with the formation of fresnoite.
Notes:
Insoluble in HCl, HNO3, H2SO4.
Health Risks:
No information on health risks for this material has been entered into the database. You should always treat mineral specimens with care.
