Get PriceWithin the potassium feldspar group, the occurrence of each potassium feldspar member varies slightly. Orthoclase is the most common potassium feldspar, forming the majority of potassium feldspar found in felsic plutonic igneous rocks, some high temperature veins, and higher-grade metamorphic rocks.
Get PriceFeldspar properties feldspar mineral group Feldspar is a silicate mineral of K, NA, Ca composed of silicon-oxygen Tetrahedra. Its main components are SiO2, Al2O3, K2O, Na2o, CaO, and MgO, which are important raw materials for manufacturing, and widely used in chemical, abrasive, glass fiber, electrode, Enamel and filler industries.

Get PriceFeldspar minerals are essential components in igneous, metamorphic and sedimentary rocks, to such an extent that the classification of a number of rocks is based on feldspar content. The mineralogical composition of most feldspars can be expressed in terms of the ternary system Orthoclase.
Get PriceFeldspars were predominantly orthoclase, but both sodium and calcium plagioclases were also present. Sample COB contained 27.7 pct saussurite, which is a major alteration product of feldspar that is always associated with finely grained material.

Get PriceAlthough petrologists had used twinning as a method of distinguishing orthoclase from microcline, Wright and Stewart (1958) used the difference in certain d values to calculate a degree of disorder of a sample and thus have a quantitative method to identify the structural state of a potassium feldspar.
Get PriceWhat Is Orthoclase? Orthoclase is a feldspar mineral with a chemical composition of KAlSi 3 O 8.It is one of the most abundant rock-forming minerals of the continental crust. Orthoclase is most widely known as the pink feldspar found in many granites and as the mineral assigned a hardness of "6" in the Mohs hardness scale.

Uses: The feldspar group is very large and there are many different chemical formulas. Before a feldspar can be used its chemical composition must be determined. Different feldspars will behave differently. Some uses for the feldspar ...
Get PriceOrthoclase is one of the most common minerals, and occurs in numerous mineral environments. It is polymorphous with the minerals Microcline and Sanidine.These three minerals form the Potassium Feldspar group.They are almost identical in physical properties, and it is sometimes impossible to distinguish one another without x-ray analysis.
Get PriceFeldspar is also used in the production of enamels, glass frits, glazes, abrasives, and welding electrodes. Special orthoclase feldspar is the natural raw material for the hard porcelain industry. Hard porcelain is characterised by its high electric strength, especially at elevated temperatures.
Get PriceMicrocline (KAlSi 3 O 8) is an important igneous rock-forming tectosilicate mineral. It is a potassium-rich alkali feldspar. Microcline typically contains minor amounts of sodium. It is common in granite and pegmatites. Microcline forms during slow cooling of orthoclase; it is more stable at lower temperatures than orthoclase.
