Once perlite is taken from the ground, processing plants crush the material into smaller pieces that are more suitable for a variety of purposes. Then, the magic begins. Workers heat the perlite to roughly 1,600 degrees Fahrenheit (871 degrees Celsius), causing the water within to expand into vapor. This "popping" reaction is where the "popcorn ...

Perlite is a manufactured granular product made from naturally occurring volcanic glass that is used in potting mix and also in industrial applications. In other words, Perlite is rock popcorn or steam …
What is perlite? Perlite is a lightweight granular material that's white in colour. It looks and feels like little bits of polystyrene but is actually made from expanded volcanic glass, heated to 1000°C until it 'pops' (like popcorn) to many times its original size. It's lightweight, sterile, and easy to handle, and is long-lasting.
The microorganisms responsible for the biotransformation of expanded perlite into organic-like substrates were analyzed for compatibility, interspecific synergy (bacteria, fungi, diazotrophs), the ...
perlite ore to temperatures of about 900°C (1,700°F) so˚ens the volcanic glass, causing entrapped water molecules in the rock to turn to steam and expand the particles like popcorn. ˛e resulting expanded particles—actually clusters of minute glass bubbles—are spherical in shape, usually ˝u˜y or frothy, highly
Nature: The result of rapidly heating raw perlite to temperatures above 2000°F (1093°C), causing the glass structure to soften and the water trapped within to vaporize, expanding the particles. Color: White or light gray, due to the reflection of the internal bubbles. Texture: Lightweight, porous, and popcorn-like. The expansion can increase its volume by 4 to …

The removal efficiencies reached the …
2. The areas of applications for perlite. Expanded perlite is a white, ultra-lightweight aggregate with particles ranging from extremely fine powder to up to 6 mm in diameter. …
The resulting expanded perlite product is lightweight, highly porous, and characterized by its unique bubble-like structure. Its physical and chemical properties …
The expanded perlite refers to the market for perlite, an amorphous volcanic glass that expands 4-20 times its original volume when rapidly heated due to water trapped in its structure. The expanded perlite has properties like high porosity, low density, high surface area, chemical & thermal stability, and heat resistance.
Elastic moduli of packed beds of expanded perlite particles (expanded siliceous volcanic glass) were investigated by elastic wave velocity measurement along the axial direction. By adopting an isotropic model for the medium, the elastic moduli Poisson's ratio and Young's modulus were measured. ... It was found that EP particles show …
The greatest advantage of using expanded perlite aggregate in cultured (manufactured) stone and brick veneer products is the weight savings—as much as a third the weight over typical mix designs. That weight savings has clear advantages: less rigorous support structure (like ledges and footings) for the veneer, and cost savings in handling ...
A lightweight rock with exceptional properties. Perlite is a naturally occurring volcanic rock formed from siliceous lava or ash. Due to rapid cooling, the lava or ash solidifies into a glass-like rock. Over tens of thousands of years, surface and groundwater infiltrates the rock and become trapped in the glass structure.
If you're trying to break up hard clay soil in a garden bed, I recommend raking a 2-inch layer of perlite into the top 6 to 12 inches of soil, then add 2 to 3 inches of quality compost and see how it goes from there. Remember that perlite doesn't decompose, so once you add it, you're permanently changing the structure of your soil.

The reason perlite insulation is technically referred to as "expanded perlite" is because when it is heated during the manufacturing process (to approximately 1600°F/900°C) the moisture expands, causing it to pop like popcorn at 1600°F. This makes perlite a very low-density material that is light-weight, with low thermal conductivity values.
Perlite makes an excellent loose-fill insulator, flowing easily into annulus and odd-shaped spaces—and then staying there. It won't settle or bridge, won't rot or attract rodents or termites. It also adds insulative value to …
