Sepiolite 2mm-4mm
Sepiolite is a clay mineral of fibrous magnisium silicate.It is a hydrous aluminum-magnesium silicate with chain structure.Usually the colour is white,light gray,pale yellew etc.Sepiolite is opaque and lusterless.It's secific gravity is 2-3.2,the hardness is 2-2.5,and melting point is 1500-1700 °C .It is innoxious,flavourless and high temperature resistance.

Advantage
Nontoxic and odorless, heat resistant,low in contraction,high in plasticity,
dissolve in hedrochloric acid, insulating and salt resistant, etc.
Main Uses:
1. 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 is an ideal material in making filter tip of cigarets.
2.Mixed with cement, it helps to reduce contraction and leaves no gaps and leaks no water. Added
to painting ,the painting can form a sediment to improve its quality.
3. It can be used as the fine mud material in well drilling for terrestrial heat ,for petroleum and halite. lt is particularly applicable for deep well drilling.
4. 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 fiber, sepiolite can be made into inorganic noncombustible paper.
5. It can be used to improve the soil as suspended agent in fertilizers and carrier of farm chemicals.lt can also be used as additive of fodder, coherent agent, improving agent for animals, oil-clearing agent in fodder sites ,etc.
6. It can be used to produce original device of special pottery, atomic radiation-resistant apparatus in making atomic energy, crockets and satellite.
7. It is the raw material for fire-resisting apparatus and clothing.
