Anorthite (IMA symbol: An) is the calcium endmember of the plagioclase feldspar mineral series. The chemical formula of pure anorthite is Ca Al 2 Si 2 O 8.Anorthite is found in mafic igneous rocks.Anorthite is rare on the Earth but abundant on the Moon.
As regards the replacement pieces, the significant presence of anorthite in CT R, together with the joint presence of diopside and gehlenite, indicated on the one hand that a temperature of over 950 °C must have been reached during firing, and also that a clayey mix made up of illite-kaolinite clays and calcite must have been used.

Feldspar is the most abundant mineral group in the Earth's crust. There are more feldspars (60%) than all the other minerals combined in the outer (13-17) km of the crust. Feldspars include three compositional endmembers: K-feldspar (KAlSi 3 O 8 ), albite (NaAlSi 3 O 8) and anorthite (CaAl 2 Si 2 O 8) Fig.1. Alkali feldspars are ...

Anorthite belongs to the Plagioclase Feldspar group, an isomorphous solid solution series. Albite is one end member, containing sodium and no calcium. The other end member, Anorthite, contains calcium and no sodium. The intermediary members are Oligoclase, Andesine, Labradorite, and Bytownite.Labradorite and Bytownite are considered by some to be a variety …

Anorthosite (/ ə ˈ n ɔːr θ ə s aɪ t /) is a phaneritic, intrusive igneous rock characterized by its composition: mostly plagioclase feldspar (90–), with a minimal mafic component (0–10%). Pyroxene, ilmenite, magnetite, and olivine are the mafic minerals most commonly present.. Anorthosites are of enormous geologic interest, because it is still not fully understood how they …

We call anorthite component A because it melts at a higher temperature than diopside. We use the same system in Table 12-1 and subsequent tables, that is, component A is always the one with the higher melting point. The molecular weights of the two silicates are 278.211 g mol −1 (anorthite) and 216.553 g mol −1 (diopside). We use Eq.

In the three glass-ceramic designs, the presence of diopside and anorthite phases in different proportions was evident, according to the Rietveld refinements. The identification of a diopside phase in glass-ceramic materials is important, as this phase contributes to the hardness of the material, in addition to imparting greater chemical resistance to corrosion [ 26, 41 ].
The objective of this work was to develop a more and better understanding of the strength developing in clay-andesite fired brick. The purpose was to improve the quality of the clay bricks that are handmade in the southern region of Ecuador to make them suitable for more widespread use in the local construction industry.
