Titanium(IV) oxide CAS 13463-67-7 Hoʻomaka
maikaʻi
ʻO ka pauka amorphous keʻokeʻo. ʻEkolu mau ʻano like ʻole o ka titanium dioxide i loko o ke ʻano: ʻo rutile kahi aniani tetragonal; ʻO Anatase kahi aniani tetragonal; ʻO ka pā perovskite he ʻano aniani orthorhombic. Melemele i ka wela iki a ʻeleʻele i ka wela ikaika. ʻAʻole hiki ke hoʻoheheʻe ʻia i loko o ka wai, hydrochloric acid a i ʻole nitric acid a i ʻole dilute sulfuric acid a me nā mea hoʻoheheʻe organik, hiki ke hoʻoheheʻe ʻia i loko o ka sulfuric acid concentrated, hydrofluoric acid, hiki ke hoʻoheheʻe ʻia i ka alkali a me ka wai nitric wela. Hiki ke hoʻolapalapa ʻia no ka manawa lōʻihi e hoʻoheheʻe ʻia i loko o ka waikawa sulfuric concentrated a me ka waika hydrofluoric. Hoʻopili ia me ka sodium hydroxide hehee e hana i ka titanate. Ma nā wela kiʻekiʻe, hiki ke hoʻemi ʻia i ka titanium haʻahaʻa haʻahaʻa e ka hydrogen, carbon, metal sodium, etc., a hana me ka carbon disulfide e hana i ka titanium disulfide. ʻO ka index refractive o ka titanium dioxide ka mea nui loa i nā puaʻa keʻokeʻo, a ʻo ke ʻano rutile he 8. 70, 2.55 no ke ʻano anatase. Ma muli o ka hoʻololi ʻana o ka anatase a me ka plate titanium dioxide i rutile i nā wela kiʻekiʻe, ʻaʻohe mea i hoʻoheheʻe ʻia a me ka paila ʻana o ka pā titanium a me anatase. ʻO ka rutile titanium dioxide wale nō ka helu heheʻe a me kahi paila, ʻo ka helu heheʻe o rutile titanium dioxide he 1850 °C, ʻo ka helu heheʻe i ka lewa (1830 honua 15) °C, a ʻo ka helu heheʻe i ka hoʻonui ʻana i ka oxygen he 1879 °C. , a pili ka helu hehee i ka maemae o ka titanium dioxide. He (3200 lepo 300) K ka paila paila o ka rutile titanium dioxide, a he maalea iki ka titanium dioxide i keia wela wela.
Kaʻina hana
Hoʻoheheʻe ʻia ka titanium oxide sulfate i ka wai a kānana. Ua hoʻohui ʻia ʻo Ammonia e hoʻoheheʻe i ka wai e like me ka gauntlet-like precipitate, a laila kānana ʻia. A laila e hoʻoheheʻe ʻia me ka hopena oxalic acid, a laila hoʻoheheʻe ʻia a kānana ʻia me ka amonia. Hoʻomaloʻo ʻia ka precipitate i loaʻa ma 170 °C a laila ʻala ʻia ma 540 °C no ka loaʻa ʻana o ka titanium dioxide.
ʻO ka hapa nui o lākou he lua hāmama. Hiki ke hoʻokaʻawale ʻia ka pōmaikaʻi ʻo Titanium i ʻekolu mau ʻanuʻu: ka hoʻokaʻawale mua (ka hoʻokaʻawale ʻana i ka magnetic a me ke ʻano hoʻokaʻawale gravity), ka hoʻokaʻawale ʻana i ka hao (ke ʻano hoʻokaʻawale magnetic), a me ka hoʻokaʻawale ʻana o ka titanium (ka hoʻokaʻawale ʻana i ka umekaumaha, ka hoʻokaʻawale magnetic, ka hoʻokaʻawale uila a me ke ʻano flotation). Hiki ke hoʻokaʻawale ʻia ka pōmaikaʻi o ka titanium zirconium placers (ʻo ka nui o nā mea hoʻonoho kahakai, a ukali ʻia e nā mea hoʻokomo i uka) i ʻelua mau pae: ka hoʻokaʻawale ʻana a me ke koho. I ka makahiki 1995, ua hoʻohana ka Zhengzhou Comprehensive Utilization Research Institute o ka Ministry of Geology and Mineral Resources i ke kaʻina hana o ka hoʻokaʻawale ʻana i ka magnetic, ka hoʻokaʻawale ʻana i ka umekaumaha a me ka leaching acid e hoʻopōmaikaʻi i ka mina rutile nui loa ma Xixia, Henan Province, i hala i ka hana hoʻokolohua, a. aia nā hōʻailona a pau ma ka pae alakaʻi ma Kina.
hoʻohana
Hoʻohana ʻia ia ma ke ʻano he spectral analysis reagent, kahi hoʻomākaukau o nā paʻakai titanium maʻemaʻe kiʻekiʻe, nā puaʻa, nā kala polyethylene, a me nā abrasives. Hoʻohana ʻia ia i loko o ka ʻoihana lāʻau lapaʻau, capacitive dielectric, kiʻekiʻe-mehana kūpaʻa i nā alloys, a me ka hana kiʻekiʻe kiʻekiʻe.
Hoʻohana ʻia ia e hana i ka titanium dioxide, titanium sponge, titanium alloy, artificial rutile, titanium tetrachloride, titanium sulfate, potassium fluorotitate, alumini titanium chloride, a pēlā aku. , nā uhi, nā electrodes welding a me nā mea hoʻoemi kukui rayon, nā plastics a me nā mea hoʻopiha pepa kiʻekiʻe, a hoʻohana ʻia i loko lako kelepona, metallurgy, paʻi, paʻi a hoʻoluʻu, enamel a me nā keʻena ʻē aʻe. ʻO Rutile nō hoʻi ka mea waiwai nui no ka hoʻomaʻemaʻe ʻana i ka titanium. ʻO ka Titanium a me kāna mau ʻāpana he mau waiwai maikaʻi loa e like me ka ikaika kiʻekiʻe, ka haʻahaʻa haʻahaʻa, ka pale ʻana i ka corrosion, ke kūpaʻa kiʻekiʻe o ka mahana, ka haʻahaʻa haʻahaʻa haʻahaʻa, non-toxicity, etc., a loaʻa nā hana kūikawā e like me ka absorption gas a me ka superconductivity, no laila ua hoʻohana nui ʻia lākou i loko. mokulele, ʻoihana kemika, ʻoihana māmā, hoʻokele, lāʻau lapaʻau, pale aupuni a me ka hoʻomohala waiwai moana a me nā ʻano ʻē aʻe. ʻOi aku ma mua o 90% o nā minerala titanium o ka honua i hoʻohana ʻia e hana i nā pua keʻokeʻo titanium dioxide, a ʻoi aku ka nui o kēia huahana i ka pena, ka lāʻau, ka plastic, ka pepa a me nā ʻoihana ʻē aʻe.
palekana
E kūʻai i loko o kahi hale kūʻai maʻalili. Hoʻopaʻa ʻia ka pūʻolo. ʻAʻole hiki ke mālama ʻia a hui pū ʻia me nā waikawa.
ʻAʻole e hui pū ʻia nā huahana mineral Rutile me nā mea ʻē aʻe i ke kaʻina o ka hoʻopili ʻana, mālama a me ka lawe ʻana. Pono ʻia ka mea ʻeke paʻa i ka corrosion a ʻaʻole maʻalahi e haki. ʻO ka ʻeke ʻeke pālua ʻelua, pono e hoʻohālikelike ʻia ka ʻaoʻao o loko a me waho, ʻo ka ʻaoʻao o loko he ʻeke ʻeke a lole paha (hiki ke hoʻohana ʻia ka pepa kraft), a ʻo ka ʻaoʻao o waho he ʻeke ulana. ʻO ke kaumaha o kēlā me kēia pūʻolo he 25kg a i ʻole 50kg. I ka hoʻopaʻa ʻana, pono e hoʻopaʻa paʻa ʻia ka waha o ka ʻeke, a paʻa ka logo ma ka ʻeke, a maopopo ke kākau lima ʻaʻole e mae. E hui pū ʻia kēlā me kēia pūʻulu o nā huahana mineral me kahi palapala hōʻoia e kūpono i nā koi o ka maʻamau. Pono e hoʻopaʻa ʻia ka waiho ʻana o nā huahana mineral i nā māka like ʻole, a maʻemaʻe ke kahua mālama.
