Overview

Oxammite is a rare mineral with the chemical formula ammonium oxalate monohydrate, (NH4)2(C2O4)·H2O. It crystallizes in the orthorhombic crystal system and belongs to the Strunz classification 10.AB.55. This mineral is characterized by its low hardness, typically less than 2 on the Mohs scale, and a low density. It exhibits a vitreous to pearly luster and is generally colorless or white in appearance. Oxammite is classified as an organic mineral due to the presence of the oxalate group. It is extremely rare and is known for its instability under normal environmental conditions.

Etymology

Oxammite is named after ammonia, a key component of its chemical composition. The mineral's name reflects the presence of the ammonium ion in its structure.

How to recognize it

Oxammite can be identified by its very low hardness, typically less than 2 on the Mohs scale, and its colorless or white color. It has a vitreous to pearly luster and a low density. A streak test will yield a white streak. Due to its rarity and instability, it is easily confused with other hydrous ammonium compounds, but its low hardness and chemical composition help distinguish it.

Trivia

Oxammite is one of the few minerals containing the ammonium ion, making it chemically unique. It is also one of the few minerals classified as organic due to the presence of the oxalate group. Its instability under normal conditions makes it a rare and fragile mineral to study in the field.
