Product Overview
Description
Expand Vermiculite
VERMICULITE, also known as VERMICULITE powder, has a density of 2.4~2.7g/cm3.
Vermiculite is a clay mineral similar to montmorillonite. It is a layered silicate.Biotite is generally formed by hydrothermal
alteration or weathering.Sometimes it appears as a thick biotite (a false biotite of vermiculite), and sometimes as a tiny,
soil-like substance.When vermiculite is heated to 300 ° c, it expands 20 times and bends.Vermiculite is a bit like a leech, hence
its name.Vermiculite is usually brown, yellow, dark green, with an oily sheen, and turns gray when heated.Vermiculite can be used
as building materials, adsorbents, fire insulation materials, mechanical lubricants, soil improvers and so on.
Vermiculite can be divided into vermiculite slice and expanded vermiculite by stages, and can be divided into golden vermiculite,
silver vermiculite and milky vermiculite by color classification.
