Vermiculite
Price:
Vermiculite
Type: Crude Vermiculite & Exfoliated Vermiculite
Detailed Introduction
Vermiculite is a hydrous phyllosilicate mineral which undergoes significant expansion when heated. Exfoliation occurs when the mineral is heated sufficiently, and commercial furnaces can routinely produce this effect. Vermiculite forms by the weathering or hydrothermal alteration of biotite or phlogopite.
Chemical Composition
SiO2: 38-46%
Al2O3: 7-9%
Fe2O3: 4-20%
MgO: 22-36%
CaO: 2.0-3.5%
K2O: 2.1-4.6%
TiO2: 0.2-1.5%
Packing: 50kg, 1,000kg, 1100kg or 1200kg bags.
VERMICULITE is the name given to a group of hydrated laminar minerals which are aluminium-iron-magnesium silicates, resembling mica in appearance.Vermiculite is a hydrous phyllosilicate mineral which undergoes significant expansion (exfoliation) when heated. It is very lightweight and mixes easily with other mediums.
Crude Vermiculite consists of thin, flat flakes containing microscopic layers of water. EXFOLIATION On being subjected suddenly to high temperatures (700°C to 1000°C) vermiculite flakes will expand to many times their original size due to the microscopic layers of water turning to steam and forcing the laminar layers apart.
Crude vermiculite from the Palabora mine consists of golden/brown flakes which are carefully classified into five grades – each having a specified range of particle sizes. The coarsest grade comprises particles ranging between 8mm and 2.8mm, while the finest grade consists of particles between 0.710mm and 0.250mm in size.
