Vermiculite is a layered structure of the water of the magnesium aluminum silicate secondary metamorphic minerals, like mica ore outside, usually by the black (K) the role of mica by hydrothermal alteration or weathering from its heat loss deflection when the expansion was like, shape similar to leech, so that vermiculite. Vermiculite is the chemical formula (Mg, Ca) 0.7 (Mg, Fe, Al) 6.0 [(Al, Si) 8.0] (OH4.8H2O) vermiculite is divided into stages according to vermiculite vermiculite ore and expansion, according to color classification can be divided into vermiculite gold, silver white vermiculite. White vermiculite. My factory production vermiculite ore roasting at high temperatures the rapid expansion of its volume can be 8-20 times the proportion of post-expansion 130-180kg/m3. Insulation in the fire with a good thermal insulation properties.

supply vermiculite as follows:
