Description: Sepiolite cashmere is silicate clay mineral in fibre form which is rich in magnesium, and it is also called magnesium and silicate mineral in moisture chain layers. It can be divided into soil Sepiolite (Stereoplasm sepiolite) came from deposition, and massiveness Sepiolite (light Sepiolite) came from hydrothermal deposit.
The specific gravity of the lightness is 2-2.3, hardness is 2-2.5. Nontoxic and odorless, it is harmless to people. its melting point is 1500-1700, so its heat resistant. It is low in contraction, but high in plasticity. It dissolves in hedrochloric acid. It is insulating and salt resistant, etc.

A. Chemical Composition:
SiO2? % | Al2O3? % | Fe2O3? % | CaO? % | Mn2O? % | Gap? % | Pulp Rate % |
40-50 | 0.2-2.2 | 0.3-2 | 2.5-20 | 17-25 | 32-48 | 10-15 |
B. Size and Physical Properties:
Item | Size (mm) | Water % | Whiteness |
Sepiolite Fibre | Super Grade, First , Second, Third Grade | ≤4 | ≤85 |
Sepiolite Powder | 100mesh, 200mesh, 300mesh, 400mesh |
Main Uses :
????? It can be used to purify oils, to make medical casing, to make organic coolant in refining atomic reactor, to absorb radioactive waste. The processed sepiolite mixed with some active carbon in an ideal material in making filter tip of cigarettes.
? Mixed with cement, it helps to reduce contraction and leave no gaps and leak no water. Added to painter, the painter can from a sediment to improve its quality.
? It can be used as the fine mud material in well drilling for terrestrial heat, for petroleum and halite. It is particularly applicable for deep well drilling.
??It can be used to make soap and detergent in the place of fatty acid, to improve quality and clearance.
? Used as additives of cosmetics , it can absorb bacteria. Mixed with glass fibre, sepiolite can be made into inorganic noncombustible paper.
? It can be used to improve the soil as suspended agent in fertilizers and carrier of chemicals. It can also be used as additive of fodder, coherent agent, improving agent for animals, oil-clearing agent in fodder sites, etc.
? It can be used to produce original device of special pottery, atomic radiation-resistant apparatus in making atomic energy, rockets and satellite.
