Calcined mica (Dehydrated mica)
Dehydrated mica ndi mica yopangidwa ndi calcining mica yachilengedwe pa kutentha kwakukulu, komwe kumatchedwanso calcined mica.
Mica yachilengedwe yamitundu yosiyanasiyana imatha kukhala yopanda madzi m'thupi, ndipo mawonekedwe ake akuthupi ndi mankhwala asintha kwambiri.Kusintha kwachidziwitso kwambiri ndiko kusintha kwa mtundu.Mwachitsanzo, mica yoyera yachilengedwe idzawonetsa mawonekedwe amtundu womwe umakhala wachikasu ndi wofiira pambuyo powerengera, ndipo biotite yachilengedwe imawonetsa mtundu wagolide pambuyo powerengera. -
Synthetic mica (fluorophlogopite)
Synthetic mica yotchedwa fluoro phlogopite .Zimapangidwa kuchokera kuzinthu zopangira mankhwala kudzera kusungunuka kwapamwamba, kuzizira ndi crystallization.Kagawo kakang'ono kake kakang'ono ndi KMg3 (AlSi3O10) F2, yomwe ili mu monoclinic system ndipo ndi silicate yokhazikika.

Mica chidutswa
Tsamba la Mica lili ndi magetsi abwino komanso makina, kukana kutentha, kukhazikika kwamankhwala komanso kukana kwa corona.Itha kupukutidwa kukhala ma flakes ofewa komanso zotanuka okhala ndi makulidwe a 0.01 mpaka 0.03 mm.
Tchipisi za Mica nthawi zambiri zimagwiritsidwa ntchito pamachubu amagetsi, magawo opondaponda, makampani oyendetsa ndege ndi ma capacitor tchipisi pamakampani a wailesi, tchipisi ta mica popanga magalimoto, tchipisi tating'onoting'ono pazida zamagetsi zatsiku ndi tsiku, telefoni, kuyatsa, ndi zina zambiri.

Zidutswa za mica (Mica yosweka)
Mica zinyalala zimatanthawuza dzina lonse la zinyalala zochotsedwa mica, zotsalira zinyalala pambuyo pokonza ndi kusenda komanso zinthu zotsala pambuyo pokonza magawo.

Phlogopite (Golden mica)
Phlogopite imadziwika ndi kung'ambika kwathunthu kwa mica, mtundu wachikasu wofiirira komanso mawonekedwe agolide.Ndizosiyana ndi Muscovite chifukwa zimatha kuwola mu otentha sulfuric acid ndikupanga yankho la emulsion nthawi yomweyo, pomwe Muscovite sangathe;Zimasiyana ndi biotite mumtundu wowala.Phlogopite akhoza dzimbiri ndi anaikira sulfuric asidi, ndipo akhoza decomposed mu anaikira sulfuric asidi kupanga emulsion njira pa nthawi yomweyo.Sodium, kashiamu ndi barium m'malo potaziyamu mu mankhwala zikuchokera;Magnesium m'malo titaniyamu, chitsulo, manganese, chromium ndi fluorine m'malo O, ndi mitundu ya phlogopite monga manganese mica, titaniyamu mica, chrome phlogopite, fluorophlogopite, etc. Phlogopite makamaka amapezeka kukhudzana metamorphic madera a ultrabasic miyala monga kimberlite ndi miyala ya miyala ya dolomitic.Mwala wodetsedwa wa magnesian ukhoza kupangidwanso panthawi ya metamorphism yachigawo.Phlogopite ndi yosiyana ndi Muscovite muzinthu zakuthupi ndi zamankhwala, choncho ili ndi ntchito zambiri zapadera ndipo imagwiritsidwa ntchito pazinthu zambiri zofunika.

Muscovite (White mica)
Mica ali muscovite, Biotite, Phlogopite, lepidolite ndi mitundu ina.Muscovite ndiye mica yodziwika kwambiri.
Mica ali ndi ntchito yotchinjiriza kwambiri, kukana kutentha, kukana kwa asidi, kukana kwa dzimbiri la alkali, komanso kuchuluka kwamafuta pang'ono.Ziribe kanthu momwe zimasweka, zimakhala ngati ma flakes, ndi elasticity yabwino komanso yolimba.Ufa wa mica uli ndi chiŵerengero chachikulu cha mainchesi mpaka makulidwe, zinthu zabwino zotsetsereka, zotchingira zolimba komanso kumamatira mwamphamvu.
Mica ufa chimagwiritsidwa ntchito m'minda ya kutchinjiriza, kutchinjiriza kutentha, utoto, zokutira, inki, chitetezo moto, mapulasitiki, mphira, zoumba, pobowola mafuta, kuwotcherera maelekitirodi, zodzoladzola, Azamlengalenga, etc. mica mankhwala zikuchokera

Sericite
Sericite ndi mtundu watsopano wamafuta am'mafakitale okhala ndi mawonekedwe osanjikiza, omwe ndi mtundu wa muscovite wa banja la mica wokhala ndi masikelo abwino kwambiri.Kachulukidwe ndi 2.78-2.88g / cm 3, kuuma kwake ndi 2-2.5, ndi kukula kwake ndi> 50. Ikhoza kugawidwa kukhala ma flakes oonda kwambiri, ndi silika wonyezimira ndi kumverera kosalala, wodzaza ndi elasticity, kusinthasintha, asidi ndi kukana kwa alkali, kutsekemera kwamphamvu kwa magetsi, kukana kutentha (mpaka 600 o C), komanso kutsika kwapakati pakukula kwamafuta, ndipo Kumtunda kuli ndi kukana kwamphamvu kwa UV, kukana bwino kwa abrasion komanso kukana kuvala.Etastic modulus ndi 1505-2134MPa, mphamvu yokhazikika ndi 170-360MPa, kumeta ubweya wa ubweya ndi 215-302MPa, ndi matenthedwe matenthedwe ndi 0.419-0.670W.(MK) -1 .Chigawo chachikulu ndi potaziyamu silicate aluminosilicate mchere, womwe ndi siliva-woyera kapena imvi-woyera, mu mawonekedwe a mamba abwino.Mapangidwe ake a mamolekyu ndi (H 2 KAl 3 (SiC4) 3. Mapangidwe a Themineral ndi ophweka ndipo zomwe zili ndi poizoni ndizochepa kwambiri , Palibe ma radioactive element, omwe angagwiritsidwe ntchito ngati zipangizo zobiriwira.
