Anorthite is characterized by a three-dimensional network structure of SiO4cap S i cap O sub 4 AlO4cap A l cap O sub 4 tetrahedra. :
: Approximately 6 to 6.5 on the Mohs scale, often used to distinguish it from softer minerals like marble or quartzite. Density : Approximately anorthite
: Highly porous anorthite ceramics are used as "green" materials for thermal insulation, sound absorption, and as catalyst carriers. Anorthite ( ) is the calcium-rich end-member of the series
Anorthite ( ) is the calcium-rich end-member of the series. While it is a primary rock-forming mineral that is relatively rare in its pure form on Earth, it is a dominant component of the lunar highlands . 1. Composition and Physical Properties Composition and Physical Properties , which is less
, which is less dense than many other silicate minerals like olivine or pyroxene.
: It is a critical component in the production of low-expansion ceramics and glass, where it helps lower sintering temperatures and increase mechanical strength.
