Perlite is a type of acidic lava erupted by volcanoes, which becomes glassy rock after rapid cooling. It is named for its pearl-like fissure structure. Pumice deposits include pumice, obsidian and resin rock. The differences among the three lie in that pumice has arc-shaped cracks formed by condensation, known as pumice structure, with a moisture content of 2-6%; resin rock has a unique resin-like luster and a moisture content of 6-10%; obsidian has a glassy luster and a shell-like fracture, with a moisture content generally less than 2%.
1. Core Characteristics: Magical Expansion Properties %% Below I will outline the main features of perlite from different perspectives: %% The characteristics of perlite can be summarized in one sentence: Originating from volcanoes, light as a feather, yet possessing remarkable skills. Its most captivating charm lies in its unique physical transformation capability and the various valuable properties derived from it.
2.
Lightweight: This is the most intuitive characteristic of expanded perlite. It is so light that it can even float on water. This property allows it to significantly reduce the self-weight of buildings when used as a construction material.
3.
Soft and Fragile: Although the raw ore has a certain hardness, expanded perlite is very brittle and can easily be crushed into powder.
4.Excellent thermal insulation: Due to its porous structure and the extremely low thermal conductivity of air, expanded perlite is a highly efficient insulating material, widely used in building walls, pipeline insulation, and industrial furnaces.
5.Good sound absorption and insulation: Its porous structure can also effectively absorb sound waves, reducing noise, and is often made into acoustic materials such as sound-absorbing panels.

| Appearance Characteristics |
Appearance: Various colors, mostly light gray, gray-green, yellow-white, etc., with pearl or lustrous luster.
|
| Physical properties |
Hardness and density: Mohs hardness 5.5 - 7, original mineral density approximately 2.2 - 2.4 g/cm³.
Expansion: At high temperatures (about 1000 - 1300°C), the volume can expand rapidly by 4 - 25 times, even up to 30 times. The expanded perlite becomes very light (low bulk density) and porous.
Fire resistance: Up to 1300 - 1380°C |
| chemical characteristics |
Main components: Silica (SiO2) accounts for approximately 68-74%, Alumina (Al2O3) is about 12%, and it contains 3-6% bound water. This is the key factor for its expansion ability.
Stability: Chemically stable, neutral (pH value), non-toxic, odorless, non-flammable, resistant to acids and alkalis (but has poor alkali resistance). |

1.Building materials:Used as lightweight thermal insulation filler, concrete aggregate, fireproof roofing, and soundproofing material.
2.Horticulture and agriculture:Soil amendment,enhance soil water retention and aeration, and serve as a substrate for soilless cultivation.
3.Industrial additives: Used as(such as in brewing, juice filtration), catalyst carrier, filler for plastics and rubber
4.Other fields:: Used as cryogenic insulation material, abrasive, explosive density regulator, etc.
