Perlite is a generic term for naturally occurring siliceous rock. It is a form of natural glass which like pitchstone, obsidian and other similar contains "combined water". Perlite (containing 1,9% – 4,8% wt. "chemical" or combined water) was formed over a few million years by the chemical weathering of obsidian at the earth's surface.
Perlite (ore CAS# 13) is an amorphous volcanic alumina–silicate rock (in colors ranging from transparent light gray to glossy black) that has a relatively high water content (2–5% w/w), typically formed by the hydration of obsidian. According to Kadey (1983), the name is derived from the
Perlite in Industry. Perlite is a versatile and sustainable mineral that is mined and processed with a negligible impact on the environment. The green community recognizes perlite-enhanced products as a high-performance solution drawn from a natural material of nearly unlimited supply throughout the world. When perlite ore is expanded by ...
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 ground water infiltrates the rock and becomes trapped in the glass structure. When heated at temperatures from 750 to 1,250°C, perlite expands ...
perlite is a glassy rock formed by the rapid cooling of volcanic acid lavas, with a Pearl fissure structure. Brittle, pearlescent and oil gloss. There is a special arc-shaped crack. Hardness 5.5~7. Density 2. 2~2. 4G/cm3. Expansion ratio of up to 7~30 times, refractoriness up to 1300~1380 ℃.
Perlite. Perlite is an amorphous volcanic glass (SiO 2) that has relatively high water content, typically formed by the hydration of obsidian. Perlite has the unusual characteristic of expanding and becoming porous when it is heated. It can …
Perlite ore is formed by magmatic processes, and water is entrapped in the perlite matrix over geologic time periods. These microscopic pockets of …
Perlite ore is formed by magmatic processes, and water is entrapped in the perlite matrix over geologic time periods. These microscopic pockets of water give perlite ore it's unique ability to "pop" under proper high-temperature …
Perlite is an amorphous volcanic glass that has a relatively high water content, typically formed by the hydration of obsidian. It occurs naturally and has the unusual property of greatly expanding when heated sufficiently. It is an industrial mineral and a commercial product useful for its low density after processing

Introduction of perlite ore Perlite is a kind of volcanic eruption acid lava, vitreous rock formed by rapid cooling. Perlite ore is a raw ore product made by crushing and screening perlite ore. Various specifications of perlite products can be …
Perlite is a volcanic glassy rock with high water content. It is formed by the obsidian hydration, or protrusion's microscopic lamellar structures or fractures. This naturally occurring rock when heated starts to expand. Once processed, this rock becomes light in weight. It is mainly used as a commercial product as well as an industrial mineral.
Perlite is a light gray glassy volcanic rock with a vitreous, pearly luster and a characteristic concentric or perlitic fracture. ... Our common perlite Ore production sizes: 0.00 mm - 0.60 mm (up to 30 Mesh) 0.00 mm - 1.00 mm (up to 18 Mesh) ... Types of kaolinite, Zeolite and montmorillonite are formed in result of weathering process.
Perlite is one of nature's most versatile and efficient minerals. It is formed by molten (magma-tic) rock, also known as volcanic glass. Over time, and during formation and cooling, water is absorbed into the raw perlite ore matrix, giving …
Perlite Ore. Perlite ore is formed by magmatic processes, and water is entrapped in the perlite matrix over geologic time periods. These microscopic …
INTRODUCTION: Perlite is a siliceous volcanic rock containing small amount of combined water. When crude perlite ore particles are heated to above 850 Deg. Centigrade, they expand to form countless sealed glassy cells which possess a number of inherent properties.
Formed from viscous lava, perlite is a volcanic glass of rhyolitic composition that contains between 2 and 5 percent water. Most volcanic glasses contain some water, including obsidian (less than 1 percent) and pitchstone (up to 10 percent). Although the exact formation process for perlite is debated, it is theorized that the lava that formed ...
Unexpanded Raw Perlite Ore is an amorphous volcanic glass that has a relatively high water content, typically formed by the hydration of obsidian. It occurs naturally and has the unusual property of greatly expanding when heated sufficiently.
Perlite (ore CAS# 13) is an amorphous volcanic alumina–silicate rock (in colors ranging from transparent light gray to glossy black) that has a relatively high water content (2–5% w/w), typically formed by the hydration of obsidian.
Why Perlite Works. Genesis in Fire Rapidly heating perlite ore to temperatures of about 900°C (1,700°F) softens the volcanic glass causing entrapped water molecules in the rock to turn to steam and expand the particles like popcorn. The expanded particles that result are actually clusters of minute, lightweight, insulating, glass bubbles.
