Feldspar consists essentially of aluminum silicates combined with varying percentages of potassium, sodium, and calcium, and it is the most abundant mineral of the igneous rocks. The two types of feldspar are. soda feldspar (7 percent or higher Na O) and potash feldspar (8 percent or higher K O).
Feldspar is one of the most abundant minerals in the earth''s crust. The feldspars include a range of compositions with a general chemical formula of xAl(Al,Si)3O8 where x can be sodium (Na) and/or calcium (Ca) and/or potassium (K).
