Feldspars are important ingredients in clay bodies and glazes. In both applications, their primary function is to supply fluxes to the formulations, but they also provide additional alumina (Al2O3) and silica (SiO2). Feldspars are naturally occurring minerals and are generally classified as either potash (potassium) or soda (sodium) …

En su composición química, los feldespatos poseen aluminosilicatos de bario, sodio, potasio y calcio. Pueden, además, contener pequeñas concentraciones de magnesio, hierro, estroncio, titanio y plomo. Dada su composición, podemos dividir a los feldespatos en 3 grandes grupos: Ortoclasas. Son los feldespatos alcalinos.

Feldspars are aluminosilicates containing varying amounts of calcium, potassium, or sodium. In glassmaking, feldspar provides alumina for improving hardness, durability, and resistance to chemical corrosion. In ceramics, feldspar is used as a flux, lowering the vitrifying temperature of a ceramic body during firing and forming a glassy phase.

The term feldspar refers to a group of alumino-silicate minerals which make up over half of the earth's crust. Valued for their high alumina and alkali content, Sibelco feldspars are used across a range of industrial applications including: Ceramics: as a fluxing agent to lower firing temperatures, bond together system components and increase ...

Potassium feldspars are the feldspar minerals in which the silicate tetrahedral and aluminum tetrahedra are bound with potassium ions, rather than sodium or calcium ions as in the plagioclase feldspar subgroup. The potassium feldspar group is composed of three mineral polymorphs, each having the same chemical composition, but slightly different ...

Feldspar. Feldspar (silicate, chemical formula Na (AlSi 3 O 8 ), where Na can also be replaced by K) is one of the main constituents of the Earth's crust. Feldspar can be characterised by: High inertness in various media. Low fine crystalline silica fraction (no labelling) (Unispar PG (W)) Whiteness (Unispar PG W).

Feldspat ist das Hauptgrundmineral von Granit, Monzonit und Syenit. Es macht ungefähr 60 Prozent dieser magmatischen Gesteine aus und verleiht Granit seine porphyritische Textur (eine Mischung aus großen Körnern mit zwischenzeitlich kleineren Körnern). Feldspate werden weiter in zwei Typen unterteilt. Sie sind in beiden ...

Feldspat. Feldspat je naziv za grupu vrlo važnih petrogenih minerala, koji izgrađuju više od 60% Zemljine kore. Feldspati se mogu javiti i u intruzivnim i u efuzivnim magmatskim stenama, što znači da mogu kristalisati i dok se magma nalazi u Zemljinoj kori, kao i kada se izlije na površinu. Takođe se mogu javiti i u određenoj grupi ...
