Feldspar: Uses And Applications

Additionally, feldspar can give the glass enhanced desirable properties such as increased hardness, durability and resistance to chemical attack. Alumina and calcium ions are responsible for these effects. It is the alkalis in the feldspar - chiefly potassium and sodium - that lower the melting temperature within the mixture.

Feldspars in sedimentary rocks

Diagenetic feldspars include K-feldspar and albite that are characterized by nearly stoichiometric, end-member composition (i.e., KAlSi 3 O 8 and NaAlSi 3 O 8, respectively) and lack of cathodoluminescence.Diagenetic K-feldspar crystals are monoclinic and, less commonly, triclinic with various degrees of Al-Si ordering, whereas diagenetic albite is …

Earthenware is a type of pottery made from a composition that includes a high percentage of ball clay, along with smaller proportions of kaolin and feldspar.It is known for its soft and porous nature, resulting in a less durable ceramic compared to stoneware or porcelain.

Feldspar Chemical Composition

Alkali feldspar is made up of solid solutions of K-feldspar and albite. Plagioclase, or a plagioclase feldspar, is a solid solution formed by the reaction of albite and anorthite. Only a small solid solution exists between K-feldspar and anorthite, and immiscibility occurs in the two other solid solutions at temperatures found in the Earth's …

If M < 10% the rock can be named alaskite (i.e. a leucocratic variety of alkali feldspar granite). Some alkali feldspar granites may be so rich in alkaline elements (Na and K) to contain Na-amphibole (richterite) and/or Na-pyroxene (aegirine): in this case, they should be classified as peralkaline granites .
