inganci
Farin amorphous foda. Akwai nau'ikan titanium dioxide guda uku waɗanda ke wanzu a cikin yanayi: rutile shine crystal tetragonal; Anatase shine crystal tetragonal; Plate perovskite shine crystal orthorhombic. Yellow a cikin ɗan zafi kaɗan da launin ruwan kasa a cikin zafi mai ƙarfi. Mai narkewa cikin ruwa, hydrochloric acid ko nitric acid ko tsarma sulfuric acid da Organic kaushi, mai narkewa a cikin maida hankali sulfuric acid, hydrofluoric acid, dan kadan mai narkewa a cikin alkali da zafi nitric acid. Ana iya dafa shi na dogon lokaci don narke a cikin sulfuric acid da hydrofluoric acid. Yana amsawa da narkakkar sodium hydroxide don samar da titanate. A yanayin zafi mai zafi, ana iya rage shi zuwa titanium maras nauyi ta hydrogen, carbon, sodium karfe, da sauransu, kuma yana amsawa da carbon disulfide don samar da titanium disulfide. Ma'anar refractive na titanium dioxide shine mafi girma a cikin fararen pigments, kuma nau'in rutile shine 8. 70, 2.55 don nau'in anatase. Tunda anatase da plate titanium dioxide suna canzawa zuwa rutile a yanayin zafi mai zafi, narkewa da wuraren tafasa na farantin titanium da anatase kusan babu su. Rutile titanium dioxide kawai yana da wurin narkewa da wurin tafasa, wurin narkewar rutile titanium dioxide shine 1850 ° C, wurin narkewa a cikin iska shine (1830 ƙasa 15) ° C, kuma wurin narkewa a cikin wadatar oxygen shine 1879 ° C. , kuma wurin narkewa yana da alaƙa da tsabtar titanium dioxide. Wurin tafasa na rutile titanium dioxide shine (ƙasa 3200 300) K, kuma titanium dioxide yana ɗan canzawa a wannan yanayin zafi.
Hanya
Ana narkar da titanium oxide sulfate na masana'antu a cikin ruwa kuma ana tacewa. An kara ammonia don hado hazo mai kama da gauntlet, sannan a tace. Sa'an nan kuma a narkar da shi da maganin oxalic acid, sa'an nan kuma a haɗe shi da ammonia. Ruwan da aka samu yana bushe a 170 ° C sannan a gasa shi a 540 ° C don samun titanium dioxide.
Yawancinsu suna hakar ma'adinan ramin budaddi. Titanium primary ore beneficiation za a iya raba uku matakai: pre-rabu (mafi yawan amfani da Magnetic rabuwa da nauyi Hanyar rabuwa), baƙin ƙarfe rabuwa (Magnetic rabuwa hanya), da titanium rabuwa (na nauyi rabuwa, Magnetic rabuwa, lantarki rabuwa da flotation hanya). Amfanin masu sanya wuri na titanium zirconium (mafi yawan masu sanya wuri na bakin teku, tare da masu sanya wuri na cikin gida) ana iya raba su zuwa matakai biyu: m rabuwa da zaɓi. A shekara ta 1995, Cibiyar Bincike ta Zhengzhou Comprehensive Utilization Research na ma'aikatar ilimin kasa da albarkatun ma'adinai ta amince da tsarin rarrabuwar kawuna, rabuwar nauyi da leaching na acid don cin gajiyar ma'adinin rutile mai girma a Xixia, lardin Henan, wanda ya wuce samar da gwaji, kuma dukkan alamu suna kan matakin farko a kasar Sin.

Ajiye a cikin ɗakin ajiya mai sanyi, mai iska. An rufe kunshin. Ba za a iya adana shi da gauraye shi da acid ba.
Ba za a haɗa samfuran ma'adinai na Rutile tare da nau'ikan ƙasashen waje a cikin aiwatar da marufi, ajiya da sufuri. Ana buƙatar kayan buhun marufi don zama mai jure lalata kuma ba sauƙin karyewa ba. Marufi mai nau'i-nau'i biyu, na ciki da na waje ya kamata a daidaita, na ciki shine jakar filastik ko jakar zane (ana iya amfani da takarda kraft), sannan Layer na waje jakar saƙa ce. Nauyin net na kowane kunshin shine 25kg ko 50kg. Lokacin shiryawa, ya kamata a rufe bakin jakar da kyau, kuma tambarin da ke cikin jakar ya kasance mai ƙarfi, kuma rubutun hannu ya kasance a bayyane kuma kada ya shuɗe. Kowane nau'i na kayan ma'adinai za su kasance tare da takaddun shaida mai inganci wanda ya dace da bukatun ma'auni.
