Potassium feldspar, also known as K-Feldspar, is a common type of feldspar mineral that is composed of potassium, aluminium, and silica. It is one of the most abundant minerals in the Earth's crust and is found in many types of rocks, including granite, gneiss, and pegmatite, that has a wide range of industrial and scientific applications. Its unique properties make it a valuable resource in a variety of fields, from manufacturing to geology. For example, it is a key ingredient in the manufacture of glass and ceramics, where it is used as a flux to lower the melting point of the materials. It is also used as filler in plastics, rubber, and other materials.
