Aluminosilicates

Description

Danny the type of minerals in the nature is very widespread: about a half of all bark of our planet, consists of aluminosilicates.

We will not dissolve aluminosilicate in water, and it is split only by fusions of alkalis, ftoristovodorodny acid and carbonates of alkaline metals. Substances of this type refractory, are thermally resistant, slowly interact with water and CO2.

Aluminosilicate can be received and it is artificial, by hydrothermal synthesis in the course of heating of oxides of aluminum, silicon and metals.

Application

One of the main scopes of the aforesaid production, the food industry is considered: here, various aluminosilicates are used as food additives of E559, E556, E555 and E554

Aluminosilicates are widely applied in porcelain production as the component substance allowing to receive finished goods - cements, ceramics, glass. The mineral and in the course of aluminum production, and also thermal and electrical insulation is demanded. Aluminosilicates conveniently and just to clear, dry and divide gas and water, and also to adsorb separate components in connections.

Types

Aluminosilicates are a number of the materials differing in physical and chemical and technical and operational qualities. Most widely, the following connections are applied:

  • Sodium aluminosilicate - represents quite viscous liquid and good alkaline reaction received in process of interaction with dioxide of silicon and various alkalis. Its structure, reminds "liquid glass", and when standing, substance is inclined to formation of gel. It is used in lotions for suntan, and also cosmetics for men and women.
  • Calcium aluminosilicate - the small, loose powder without characteristic smell which is applied as a divider, adsorbent, and also the food additive interfering a komkovaniye and caking. Most often, he can be met in powdered milk, bakery products and other products, and also softeners and cleaners of water.
  • Potassium aluminosilicate - is similar calcium aluminosilicate, but more disperse on structure. Except use in the food industry, he can be met often in dietary supplements and substitutes of salt. Also, this substance is used as a furnace charge component in the course of production of ceramics, glass and technical adsorbents.
