Product Description
Quality Manufacturer Raw Gold Mine Expanded Vermiculite
Classification: vermiculite flakes, expanded vermiculite, golden vermiculite, silver vermiculite, etc.
coarse vermiculite
Vermiculite is a member of the phyllosilicate minerals, similar in appearance to mica. Found all over the world, vermiculite is basically a hydrated mica that has the remarkable ability to expand to many times its original volume when heated at 850 -1100°C.
Coarse vermiculite consists of gold vermiculite and silver vermiculite which are carefully sorted into a variety of sizes including
0.3-1mm1.5-2.5mm 0.5-1.41mm 1-2.8mm 2-4.75mm 3.2-7mm 6-9mm etc.
Expanded Vermiculite
The exfoliation process is done commercially by passing coarse vermiculite through a furnace chamber in a controlled manner. The coarse vermiculite then expands at right angles to the cleavage plane, producing accordion-shaped particles that are several times its original volume. Exfoliated vermiculite size, including 0.5 -3mm1-3mm1-4mm 2-4mm 2-3mm 3-5mm3-6mm4-8mm6-8mm, special size can be
