Psilomelane, erroneously, and uncommonly known as black hematite (but not related to true hematite, which is an iron ore), is a group name for hard black manganese oxides such as hollandite and romanechite. Psilomelane consists of hydrous manganese oxide with variable amounts of barium and potassium.
