Turkey's perlite mine Çankırı ORTA has very high reserves and has an important position in the world market. There are very rich perlite reserves, especially in Central Anatolia. As Akper Perlit Madencilik, we produce run-of-the-mill ore, crushed, sieved, and expanded perlite.
Perlite is a glassy volcanic rock. Thanks to its loose structure and fragile crystalline structure, it looks like a small pearl. Thanks to its porous structure, it has high sound insulation and water absorbency. While perlite is made ready for use, it is sized according to its usage area.
When perlite is heated suddenly between 750-1200 °C, it expands under the influence of the steam released from its structure and turns into a foam aggregate consisting of glassy grains. It can expand up to 20 times its initial volume. This product is called expanded perlite.
Expanded perlite is formed when normal pyrite is heated. Heating perlite in the range of 1,560-1,650°F (850-900°C) causes the mineral to soften, and water trapped in the volcanic glass evaporates and attempts to escape through the structure. Additionally, perlite has a pH value of 6.6 to 7.5.
"Perlite", meaning pearl stone, is a glassy volcanic rock that can occur in different colors from shades of gray to black. The ore perlite in this state is called "raw perlite".
Perlite is a type of volcanic glassy rock. Perlite is also the name given to naturally occurring silica-based volcanic rocks.
It is frequently used in agricultural and plant breeding enterprises. It is an effective material used in the construction and construction industry. It is frequently used in different ways in the industrial sector, chemical and pharmaceutical industries, ceramics, and glass industries.
It is used in many other ways, such as perlite use in the construction industry, perlite use in the agricultural sector, as a filter aid in the food, pharmaceutical, and chemical industries, as a filler in the pharmaceutical and chemical industries, as a thermal insulation material in industry, and for slag or slag cleaning in metallurgy.
