HOLLANDITE Meaning and
Definition
-
Hollandite is a mineral that is classified as a member of the oxide mineral group. It is named after Henry Holland, an English mineralogist who first described it in 1822. Hollandite is primarily composed of the mineral barium manganese oxide (Ba(Mn4+6Mn3+2)O16). Its chemical formula can be represented as Ba(Mn,Ti)8O16, where manganese and titanium may substitute for each other in the crystal lattice structure.
Hollandite usually occurs as small black crystals or as thin botryoidal or crust forms in hydrothermal vein deposits. It is commonly associated with other minerals such as quartz, calcite, and other manganese oxide minerals. The mineral exhibits a characteristic metallic luster and may display a reddish-brown streak when powdered. It has a Mohs hardness ranging from 6 to 6.5, indicating its relatively good resistance to scratches and abrasion.
While hollandite is not a widely known mineral, it has several industrial uses. One of its notable applications is as a catalyst in the production of certain chemicals and materials. It can help facilitate chemical reactions by increasing the rate of reaction or reducing the temperature required for the reaction to occur. Additionally, hollandite is sometimes used as an additive in glass and ceramic manufacturing processes.
In summary, hollandite is a black mineral composed mainly of barium manganese oxide. It occurs in hydrothermal vein deposits and exhibits metallic luster. It is utilized as a catalyst and in glass and ceramic manufacturing.
