Perlite is a volcanic vitreous aluminosilicate rock whose root cause is acid lava, injected superficially or underwater during volcanic activities. The latter then cooled and solidified rapidly, under conditions that did not allow the atoms of the mineral to be placed in crystal lattice formations, which eventually gave perlite its vitreous form.
A very important factor that influenced the formation of perlite was the presence of water and various gases trapped in its mass at the time of cooling and solidification. The name comes from its texture characterized by the presence of grains, reminiscent of small pearls (pearls). Petrographically, perlite is a volcanic material. It has a characteristic perlite structure consisting of concentric breaks that look like pearls that are placed all over the glass, sometimes circular and sometimes in polygonal formations.
This is also the pronounced characteristic of perlite. The aforementioned breaks are a phenomenon observed in acidic glasses.
The basic product of the company, perlite, is a natural product, it is friendly to humans and the environment. Perlite has many uses in the construction and agricultural sectors.
Perlite is a volcanic material that includes crystalline water in its mass. The existence of this water is responsible for the most important physical property of perlite, which is its ability to expand at temperatures of 800 - 1000 Celcius.
A white mass of tiny glass bubbles is formed by abrupt controlled heating, perlite swells and trapped water evaporates.
Its volume increases 10 to 20 times with a corresponding decrease in its specific gravity, thus acquiring special thermal and sound insulation properties, while at the same time it becomes extremely porous. Thanks to its above properties, perlite is an indispensable component of light mortars, an excellent substrate for hydroponic crops and an important component of ceiling tiles for sound insulation.
