Isingeniso esifushane mayelana ne-mica yemvelo

I-Mica yemvelo igama elivamile lamaminerali omndeni we-mica, futhi iyi-silicate enesakhiwo esinezingqimba ze-potassium, i-aluminium, i-magnesium, insimbi, i-lithium nezinye izinsimbi, okuhlanganisa i-biotite, i-phlogopite, i-muscovite, i-lepidolite, i-sericite, i-mica eluhlaza, kanye iron lithium Mica njalonjalo. Empeleni akulona igama lohlobo oluthile lwedwala, kepha igama elijwayelekile lamaminerali eqembu le-mica. Kuyisilicate enesakhiwo esigqinsiwe se-potassium, i-aluminium, i-magnesium, i-iron, i-lithium nezinye izinsimbi. Amaminerali ahlukene aqukethe izakhi ezahlukene kanye nezindlela zabo zokwakheka. Kukhona futhi umehluko omncane, ngakho-ke kukhona umehluko ekubukekeni kwazo, umbala, nezici zangaphakathi.

I-Mica iyiminerali engeyona eyensimbi, equkethe izithako ezahlukahlukene, ikakhulukazi ezibandakanya i-SiO 2, okuqukethwe ngokuvamile cishe kungama-49%, kanti okuqukethwe ku-Al 2 O 3 cishe kungama-30%. Ine-elasticity enhle nokuqina. Izinto zokuvala umoya, ukumelana nokushisa okuphezulu, ukumelana ne-asidi ne-alkali, ukumelana nokugqwala, ukunamathela okuqinile nezinye izici, kuyisengezo esihle kakhulu. Isetshenziswa kabanzi ezintweni ezisebenza ngogesi, izinduku zokushisela, iraba, amapulasitiki, ukwenza iphepha, upende, ukumboza, izingulube, izitsha zobumba, izimonyo, izinto zokwakha ezintsha nezinye izimboni ezinokusetshenziswa okuhlukahlukene. Ngokuthuthuka okuqhubekayo kwesayensi nobuchwepheshe, abantu bavule izindawo ezintsha zokufaka izicelo.

Izici zayo nokwakheka kwamakhemikhali okuyinhloko: amakristalu eMuscovite angamapuleti namakholomu ayizinhlangothi eziyisithupha, indawo ehlanganisiwe iyisicaba, kanti amaqoqo ayizingqimba noma izikali, ngakho-ke ibizwa ngokuthi i-mica ehlukanisiwe. I-Mica yemvelo imhlophe, isobala futhi iyashintshashintsha, futhi inokuthungwa okumsulwa futhi ayinawo amachashazi. I-Mica inezinzuzo zokumelana nezinga lokushisa eliphakeme (kufika ku-1200 ℃ noma ngaphezulu), ukumelana okuphezulu (izikhathi eziyi-1000 ngaphezulu), ukumelana ne-asidi eningi kanye ne-alkali, obala, ukuhlukana nokunwebeka. Ishidi lokuvikela imicah elenzelwe umkhumbi-mkhathi. Izinto eziyisisekelo eziyisisekelo njengamashidi wokuvikela ama-mica wokuqapha ama-satellites kanye namashidi wokufakelwa kwe-mica amashidi wesigaba se-radar nawo anethemba lokusebenzisa okuhle emkhakheni wezokwelapha nowezempilo.

Njengesakhiwo esivamile esinezingqimba i-aluminosilicate amaminerali emvelo, i-mica inokudluliselwa kokukhanya okukhethekile okubonakalayo kanye nezakhiwo zokuvikela i-ultraviolet, futhi inezinzuzo zokushisa okuphezulu kagesi, ukumelana ne-asidi ne-alkali, nokuzinza okuphezulu kwezinga lokushisa. Kuyithuluzi elenziwa ngogesi eliguquguqukayo nelisobala ngokuzayo. Izinto ezifanelekile emikhakheni efana ne-. Kodwa-ke, isivuno esiphansi kanye nentengo ephezulu ye-mica yemvelo kunciphisa kakhulu ukusetshenziswa kwayo.
