aluminum silicate
Introduction to Aluminum silicate:
Aluminum silicate is a mineral formed by a mixture of aluminum, silica and oxygen and hence the formula Al2 (SiO3)3. It has low bulk density and a super white color.
Chemistry is widely used in day to day activities watch out for my forthcoming posts on Aluminum Periodic Table and What is Chemical Formula. I am sure they will be helpful.
Properties & Uses of Aluminum silicate
Some of the properties of aluminium Silicate are:
Lighter in weight
Super white in color
High degree of brightness
Low plasticity
Ease of dispersion
Good oil absorption.
Aluminum silicate has a remarkable use in paint industry as a filler and antisetting agent and in rubber industry; it is used as a partial reinforcing agent.
It can be manufactured by processing of aluminium silicate minerals found naturally. It can also be prepared by precipitation that gives much better properties because of smaller particle sizes and higher strength value.
Aluminum silicate comes in three different forms — Andalusite, Sillimanite and Kyanite. They all have the chemical composition Al2SiO5, but are polymorphic having different crystal structures. All three forms occur under different temperatures and pressures so are rarely found in the same rock.
Kyanite or Kaolinite is the most widely industrially used mineral. It can be prepared either by weathering feldspar chemically or by decomposing Al silicate rocks. Because of their soft fine texture, molding them is easy. Generally found in white turn to shades of orange to red on reaction with iron oxide. They are partially replaced with TiO2 as they are economical.
Aluminum Silicate minerals are used in bulk for some special applications such as making fine porcelains, paper coating and are used in industries like paints, plastics and fiberglass. It is also used in glassmaking as a refractory or catalyst due to its insolubility. Pesticides containing aluminum silicate can replace organic pesticides. The substance called ultramarine Blue that is prepared by heating kaolin, sodium carbonate, sulfur is used to treat upset stomach medically.
Conclusion for Aluminum silicate
As aluminum silicate has very low moisture content, it improves electrical as well as mechanical properties of the composite thus making it fireproof. Various forms of the mineral are used to make gem stones because of their ability in strength retention even at high temperatures.
