Name:sepiolite;
Category: hydrous magnesium silicate clay minerals;
Chemical formula:(Si*2)(Mg8)O*0(OH)4(OH2)4·8H2O;
Density:2～2.5g/cm3;
Hardness:2～3;
Properties: water bearing magnesium rich silicate clay mineral with chain structure, orthorhombic or monoclinic system, usually lump, soil or fibrous aggregate. Fresh surface is pearl luster, and after weathering is earth like luster;
Color: white, gray, dark gray, brown, red, blue and green rose;
Features: slippery and astringent, sticky tongue. It is brittle in dry condition. The shrinkage rate is low, the plasticity is good, the specific surface is large, and the adsorbability is strong. It is dissolved in hydrochloric acid and light in quality. Sepiolite also has the functions of decolorization, heat insulation, insulation, corrosion resistance, radiation resistance and thermal stability. It has strong adsorption, decolorization and dispersion properties. It also has high thermal stability, high temperature resistance up to ***0~***0℃ degrees, and its modeling, insulation and salinity are very good;
Chemical composition:SiO**4~*0%,MgO *1~*5%,and often contain a small amount of iron, manganese and other elements;
Classification:

1. According to the morphological characteristics of its output, it is divided into soil like sepiolite and massive sepiolite;
2. Its crystal morphology is divided into α sepiolite and β sepiolite;
