6.  Main Features and Application of Sepiolite 

1) Features:

Sepiolite is a rare mineral in nature.

It is one kind of of magnesium-rich, fibrous ,silicates minerals.

The main performance is heat-stability, strong adsorption, salt resistance, acid resistance, non-Pollution .

2) Application:

1.It can be used to purify oils, to make medical casing, to make organic coolant in refining atomic reactor, to absorb radioactiove waste. The processed sepiolite mixed with some active carbon is an ideal material in marking filtertip of cigaretes.

2. Mixed with cement ,it heples to reduce contraction and leave no gaps an leak no water. Added to painter, the painter can form a sediment to improve its quality.

3. Itacan bused as the fine mud material in well drilling forterrestrial heat, for petroleum and halite. It is particuliary applicable for deep well driling.

4. It can be used to make soap and detergent in theplace of fatty acid , to improve quaility and clearance.

5. Used as additives of cosmetics, it can absorb bacteria.Maixed with glass fibre, sepiolite can be made into inorganic noncombustible paper.

6. It can be used to improve the soil as suspended agent in fertilizers an carrier of farm chemicals. It can also be used as additive of fodder ,coherent agent, improving agent for animals ,oil-cliearing agentin fodder siters,etc.

7. It can beused to produce original device of sepical pottery, atomic radiation-resistant apparatus in making atomic energy,rockets and satellite.

8. It is the raw material for fire-resissting apparatus and clothing.
