An inert stone containing high silica content, formed at natural high temperatures in volcanic lava flows or artificially produced through thermal reactions, will produce perlite rock.
Perlite stone has a cavernous form (porous form) so perlite has a large volume but extremely light.
Due to that characteristic, humans have long applied perlite stone features to create high quality ceramics with very light weight. and later people took advantage of that to make ultra-light concrete with extremely good sound insulatio
Insulation properties of Perlite stone: due to the melting temperature at 1260 degrees C and in the cave form, perlite stone is used in fireproof materials in safes, fireproof doors, chimney lining …
Perlite stone has the ability to reduce the spread of sound between walls, so it is often used in recording studios, meeting rooms, karaoke rooms …
And the most important is the extremely efficient agricultural applicability,
Most growers in the US use perlite rock mixed at a rate of 30% – 50% (depending on the crop) with nutrient soil to grow conventional plants, or mix with inert varieties. Other hydrated like rockwool or soft white. In Vietnam, often mixed with copra meal has been processed tannin.
Because perlite rock has a cavernous structure, it can hydrate, nutrients, regulate the humidity temperature for the growing material to make the soil airy and porous to help the root system grow very strong. Since then the tree will produce fruit with high yield, more flowers and more beautiful.
