Professional Manufactory Produce Sepiolite Rough Stone??
Brief Introduction
?
Sepiolite is a fibrous hydrous magnesium silicate, usually white, light grey, yellow wait for color, not transparent and without burnish.They are shaped like a clod, into a strange crusty or nodular.Under the electron microscope can see them is by countless filaments together in sheets.Sepiolite has a strange characteristics, absorb a lot of water when they encounter water to become soft, and once dry and harden.?
?
Sepiolite belong to orthorhombic system or single orthorhombic system;Color changes, usually pale white or gray;With a silky luster, sometimes is waxy luster;With a white streaks, opaque, feel smooth and sticky tongue;Between 2 ~ 2.5 mohs hardness;Light body, from 1 to 2.2 g/cm3 density;Low shrinking rate, plasticity is good, can dissolve in hydrochloric acid.
The chemical composition of sepiolite for silicon (Si) and magnesium (Mg);Its standard crystal chemical formula for Mg8 (H2O) 4 [Si6O16] 2 (OH) 4 · 8 H2O, which SiO2 content is in commonly between 54-60%, content of MgO style more in the range of 21 to 25%.
Sepiolite with a strong adsorption, decolorization and dispersion, such as performance, also have high thermal stability, resistance to high temperature can reach 1500 ~ 1700 ℃, modelling, insulation resistance, salinity, is very good.??
