01 / Technical dossier
The material. The evidence.
Reference properties and the analytical work needed to assess this material for industrial use.
TO-REF-MICA
Revision 1.0 · Technical reference
Material identity
Variable; muscovite KAl₂(AlSi₃O₁₀)(OH)₂
Mica is a mineral group, including muscovite and biotite. Identify the mica species rather than assigning one universal composition.
