Feldspar iMinerals Inc.
The feldspar group minerals are the most abundant minerals in the earth's crust. High concentrations of alumina (Al 2 O 3) and alkalis (K 2 O and Na 2 O) together with low levels of trace elements such as iron (reported as the oxide Fe 2 O 3) define a highquality feldspar product.Alumina adds hardness, durability and resistance to chemical corrosion while the alkalis act as a flux lowering
A Detailed Overview of Feldspar: Types, Properties, and Uses
Feb 24, 2018 · ┗ A bluishgreen feldspar mineral is called amazonite. ┗ Albite is an example of a feldspar that can be considered both, alkali as well as plagioclase. Uses of Feldspar ┗ Feldspar contains alumina, which results in an increase in the strength of the manufactured product. Therefore, this mineral is used in glassmaking.
Plagioclase Wikipedia
Plagioclase is a series of tectosilie (framework silie) minerals within the feldspar group. Rather than referring to a particular mineral with a specific chemical composition, plagioclase is a continuous solid solution series, more properly known as the plagioclase feldspar series (from the Ancient Greek for "oblique fracture" in reference to its two cleavage angles).

5.2 Chemical Weathering – Physical Geology
The kinds of changes that take place are highly specific to the mineral and the environmental conditions. Some minerals, like quartz, are virtually unaffected by chemical weathering, while others, like feldspar, are easily altered. In general, the degree of chemical weathering is greatest in warm and wet climates, and least in cold and dry

Feldspar Distinctions, Characteristics & Identifiion
Aug 10, 2019 · This mineral is often called potassium feldspar or Kfeldspar because potassium always exceeds sodium in its formula. Potassium feldspar comes in three different crystal structures that depend on the temperature it formed at. Microcline is the stable form below about 400 C. Orthoclase and sanidine are stable above 500 C and 900 C, respectively.
