Sepiolite
Sepiolite is a silicate clay mineral in fiber which is rich in magnesium, and it is also called mangnesium and silicate mineral in moisture chain layers.lt can be divided into soil sepiolite (stereoplasm sepiolite) coming from deposition and massiveness sepiolite (light sepiolite) coming from hydrothermal deposit.
The specific gravity of the lightness is 2-2.3,hardness is 2-2.5.poisonless and odourless, it is harmless to people. lts melting point is 1500-1700, so it’s heat resistant. It is low in contraction,but high in placticity. lt dis-solves in hydrochloric acid. lt is insulant and salt resistant,etc
