Keeping mica flakes or flake morphology; fine by earthy, clay and other mineral indistinguishable. Vermiculite calcined at 800 ~ 1000 ℃ 0.5 to 1 minute, the rapid expansion of the volume increase of 8 to 15 times as high as up to 30 times, expanded vermiculite average bulk density of 100 ~ 130kg / m3, calcined after expansion Vermiculite has a small air gap layer, so with excellent insulation. Since vermiculite after firing a light density, resistance to cold, heat insulation, sound absorption properties, it is widely used in construction, electricity, petroleum, chemical, metallurgy, textile, agriculture and food industries.
