Taƙaitaccen gabatarwa game da mica na halitta

Mica na halitta shine kalma na gaba ɗaya don ma’adanai na dangin mica, kuma silicate ne tare da tsarin da aka tsara na potassium, aluminum, magnesium, iron, lithium da sauran karafa, ciki har da biotite, phlogopite, muscovite, lepidolite, sericite, koren mica, da iron lithium Mica da sauransu. A zahiri ba sunan wani nau’in dutse bane, amma sunan gabaɗayan ma’adanai na ƙungiyar mica. Siliki ne wanda ke da tsari na potassium, aluminum, magnesium, iron, lithium da sauran karafa. Ma’adanai daban -daban sun ƙunshi abubuwa daban -daban da hanyoyin samuwar su. Hakanan akwai ƙananan bambance -bambance, don haka akwai wasu bambance -bambance a cikin bayyanar su, launi, da kaddarorin su na ciki.

Mica ma’adinan da ba ƙarfe ba ne, wanda ya ƙunshi abubuwa iri-iri, galibi sun haɗa da SiO 2, abun ciki gabaɗaya kusan 49%ne, kuma abun ciki na Al 2 O 3 kusan 30%. Yana da kyau elasticity da tauri. Rufewa, tsayayyen zafin jiki, juriya na acid da alkali, juriya na lalata, adhesion mai ƙarfi da sauran halaye, kyakkyawan ƙari ne. Ana amfani dashi sosai a cikin kayan lantarki, sandunan walda, roba, robobi, yin takarda, fenti, fenti, pigments, yumbu, kayan kwalliya, sabbin kayan gini da sauran masana’antu masu fa’ida mai yawa. Tare da ci gaba da haɓaka kimiyya da fasaha, mutane sun buɗe sabbin wuraren aikace -aikacen.

Halayensa da babban abun da ke tattare da sinadaran: Muscovite lu’ulu’u ne masu faranti na hexagonal da ginshiƙai, haɗin haɗin gwiwa yana da lebur, kuma aggregates flakes ne ko ma’auni, don haka ake kira mica fragmented. Halittar mica fari ce, mai haske kuma mai haske, kuma tana da tsattsarkan tsari kuma babu tabo. Mica yana da fa’idar juriya mai zafi mafi girma (har zuwa 1200 ℃ ko sama), mafi girman ƙarfi (sau 1000 mafi girma), ƙarin juriya na acid da alkali, nuna gaskiya, rarrabuwa da taushi. Ita ce takardar rufe fuska ta mica ta roba don jiragen sama. Babban mahimman kayan kamar su mica roba mai ruɓewa don saka idanu kan tauraron dan adam da zanen gado na mica wanda aka rarrabasu don masu sauya lokacin radar suma suna da kyakkyawan fatan aikace -aikace a fannonin kiwon lafiya da kiwon lafiya.

A matsayin tsari na yau da kullun na aluminosilicate na ma’adinai na halitta, mica yana da watsawar haske na musamman na bayyane da kaddarorin garkuwar ultraviolet, kuma yana da fa’idodin babban rufin lantarki, juriya acid da alkali, da kwanciyar hankali mai zafi. Na’urar lantarki ce mai sassauƙa da nuna gaskiya a nan gaba. Abubuwan da suka dace a fannoni kamar. Koyaya, ƙarancin amfanin ƙasa da babban farashin mica na halitta yana iyakance aikace-aikacen sa sosai.
