Factory Supply Sepiolite Fiber Sepiolite Powder Sepiolite for Drilling Brake Lining Thermal Mortar

  Sepiolite is rich of magnesium fibrous silicate clay mineral, the mainly chemical composition is (Si) and the magnesium (Mg) composes for the silicon, often assumes compact massive, earthy or fibrous, generally assumes the white, the gray or slightly brings the light red, dark green and brown. The adsorption performance and the heat-stable performance are excellent, thermostable and the electric insulation performance is good, the shrinkage is low, it's not easy to crack, as well as anti-salinity higher special performance.Physical property: The ore assumes clayey, the pellet is very thin, the naked eye is very difficult to distinguish, the color many to be pessimistic, or be brown. The sepiolite content is 20 generally--40%, other impurities are the quartz, the talc, the calcite and so on. This kind of ore reserve is rich, the application is widespread. The color is changeable, white majority, but also has light yellow, is light gray, is dark green, is not transparent, feel agglutination, the volume is big, proportion 2-2.5, non-toxic, tasteless, harmless , incombustible, the highest heat resistant 1750 degrees, the water-absorptivity in 1.5 times which is self-possessed, the catalysis, the absorptive quality is good.Chemical property: The molecular formula is: Mg (H2O) 8H2OSiO2 52%--65%; MgO 15%--25%; Moisture content
