This page is currently not sponsored. Click here to sponsor this page.
Formula:
Pb2(OH)3(NO3)
System:
Orthorhombic
Colour:
Colourless, white, pale ...
Anthropogenic lead hydroxide nitrate (formed on late medieval mine dumps due to the use of nitrate explosives) described by Kolitsch & Tillmanns (2003).

Forms colourless to white laths. Often associated with pseudo-octahedral Unnamed (Pb13O8(OH)6(NO3)4).
Insoluble in hot water.

Also recently found in a Pb-rich slag (Kolitsch, data from 2012, to be published).
