What is the chemical formula for potassium feldspar?
KAlSi3O8
Potassium feldspar refers to a number of minerals in the feldspar group, and containing potassium: Orthoclase (endmember formula KAlSi3O8), an important tectosilicate mineral that forms igneous rock.
What mineral is feldspar?
Feldspar is the name given to a group of minerals distinguished by the presence of alumina and silica (SiO2) in their chemistry. This group includes aluminum silicates of soda, potassium, or lime. It is the single most abundant mineral group on Earth.
What is the formula of fluorspar?
CaF2
CHARACTER AND OCCURRENCE. Fluorspar, or fluorite, chemically calcium fluoride (CaF2), consists of calcium and fluorine in the proportions of 51.1 to 48.9.
What is feldspar made of?
Chemically, the feldspars are silicates of aluminium, containing sodium, potassium, iron, calcium, or barium or combinations of these elements.
Is feldspar an element?
What are the elements of potassium feldspar?
All the rock-forming feldspars are aluminosilicate minerals with the general formula AT4O8 in which A = potassium, sodium, or calcium (Ca); and T = silicon (Si) and aluminum (Al), with a Si:Al ratio ranging from 3:1 to 1:1.

What is feldspar used to make?
Feldspars are used widely in the glass and ceramics industries. Alkali feldspars are more commonly used commercially than plagioclase feldspars. Albite, or soda spar as it is known commercially, is used in ceramics.
