Orthoclase Wikipedia

Orthoclase, or orthoclase feldspar (endmember formula KAlSi3O8), is an important tectosilicate mineral which forms igneous rock The name is from the Ancient Greek for "straight fracture," because its two cleavage planes are at right angles to each other It is a type of potassium feldspar, also known as Kfeldspar The gem known as moonstone (see below) is largely composed of orthoclase The name orthoclase refers to the rightangle cleavage possessed by the mineral Feldspar is derived from the German word feld, meaning field Orthoclase and microcline have the same chemical composition Both are potash feldspars, but both may contain sodiumOrthoclase Mineral Information photos and Facts, gemsOne of the most important materials for medium and high temperature ceramic glazes Potash feldspars are often not as pure and white as soda spars A feldspar is typically referred to as 'potash' if there is significantly more potassium than sodium (typically there will be 25% Na 2 O)Potash Feldspar DigitalfireOrthoclase: Viswanathan K, Kielhorn H M (1983) Al,Si distribution in a ternary (Ba,K,Na)feldspar as determined by crystal structure refinement American Mineralogist 68 122124: 1983: Yugoslavia: 0: 293: : OrthoclasePotash Feldspar: Mineral information, data and localitiesAlthough 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 feldsparOrthoclase: Mineral information, data and localities
