Sodium Feldspar

Feldspar is by far the most abundant group of minerals in the earth’s
crust, forming about 60% of terrestrial rocks. Most deposits offer
sodium feldspar as well as potassium feldspar and mixed feldspars.
Feldspars are extracted from metamorphic, granite rock formations
called plutons. This mineral can be found in color pink, white, gray, or
Chemically, the feldspars are silicates of aluminum, containing sodium,
potassium, iron, calcium, or barium or combinations of these elements.
Feldspar is actually used in different applications in various industries.
You can say that it is a part of our life.

Main Uses of Sodium Feldspar

Basically, we may not have noticed it but sodium feldspar is around us –
we use them every day. For example:
 Glass – it is one of the most important raw materials needed
when manufacturing glass. It acts as a fluxing agent that controls
the viscosity of the glass.
 Ceramics – after clay, feldspar is the second most important raw
material when manufacturing ceramic. It can make the ceramic
more tough and durable.
 Fillers – because of its incomparable dispersibility, it can become
good filler for paints, rubber, and plastics.
 Enamel Frits and glazes – feldspar can assist in the composition of
enamel that can help in making the finish of the product neat and
 Others – feldspar is used as a raw material in manufacturing
paint, abrasives, latex foam, production of steel, road aggregate,
and many others.
