Mica ndi dzina lambiri la mchere wa gulu la mica.Ndi aluminosilicate ya potaziyamu, aluminiyamu, magnesium, chitsulo, lithiamu ndi zitsulo zina, zonse zomwe zimakhala zosanjikiza ndi monoclinic.Krustalo ndi pseudohexagonal lamellae kapena mbale ngati, nthawi zina columnar.Lamellar cleavage ndi yokwanira kwambiri, yokhala ndi magalasi owala komanso pepala lotanuka.Mlozera wa refractive wa mica umachulukitsidwa ndi kuchuluka kwa chitsulo, kuchokera pakutsika pang'ono kupita ku protrusion yapakatikati.Zosiyanasiyana zopanda chitsulo zimakhala zopanda mtundu mu flake.Kukwera kwachitsulo kumapangitsa kuti mtundu wake ukhale wakuda, komanso polychromatic ndi mayamwidwe.

Mica flake kukula: 6-10mesh, 10-20mesh,
Mica powder: 200mesh, 325mesh, 600mesh, 800mesh, 1250mesh, 2000mesh, 3000mesh ndi 5000mesh.

Kugwiritsa ntchito
M'makampani, biotite amagwiritsa ntchito kwambiri kutchinjiriza ndi kukana kutentha, komanso kukana kwa asidi, kukana kwa alkali, kukana kukanikiza ndi kukana peeling, monga zida zamagetsi zamagetsi ndi zida zamagetsi;chachiwiri, amagwiritsidwa ntchito popanga mazenera ndi magawo amakina a ma boiler a nthunzi ndi ng'anjo zosungunulira.Mica tchipisi ndi mica ufa akhoza kukonzedwa mu mica pepala, ndipo akhoza m'malo mica pepala kupanga zosiyanasiyana zotsika mtengo ndi yunifolomu makulidwe insulating zipangizo.
