| Na Waiwai Kino a Kimia | Pauda keʻokeʻo.
ʻO ka pauka keʻokeʻo me ke ʻano palupalu, ʻala ʻole a ʻono ʻole, ka mana huna ikaika a me ka mana kala, ka helu heheʻe 1560 ~ 1580 ℃. ʻAʻole hiki ke hoʻoheheʻe ʻia i loko o ka wai, hoʻoheheʻe ʻia ka waika inorganic, solvent organik, ʻaila, hiki ke hoʻoheheʻe ʻia i ka alkali, hiki ke hoʻoheheʻe ʻia i loko o ka waikawa sulfuric concentrated. Huli melemele ke wela a keʻokeʻo ma hope o ka maʻalili. ʻO ka Rutile (R-type) ka nui o 4.26g/cm3 a me ka helu kuhikuhi refractive o 2.72. R ʻano titanium dioxide maikaʻi ke kū i ka wā, kū i ka wai a ʻaʻole maʻalahi i nā hiʻohiʻona melemele, akā ʻilihune keʻokeʻo. Anatase (Type A) he 3.84g/cm3 ka mānoanoa a me ka index refractive o 2.55. ʻAno maikaʻi ʻole ka titanium dioxide māmā, ʻaʻole kū i ka wā, akā ʻoi aku ka maikaʻi o ka keʻokeʻo. I nā makahiki i hala iho nei, ua ʻike ʻia ʻo ka nano-sized ultrafine titanium dioxide (maʻamau 10 a 50 nm) he Semiconductor waiwai, a he kiʻekiʻe kūpaʻa, kiʻekiʻe transparency, hana kiʻekiʻe a me ka dispersibility kiʻekiʻe, ʻaʻohe toxicity a me ka hopena kala. |
| Hoʻohana | Hoʻohana ʻia i ka pena, ka inika, ka plastic, ka ʻōpala, ka pepa, ka fiber kemika a me nā ʻoihana ʻē aʻe; Hoʻohana ʻia no ka welding electrode, hoʻomaʻemaʻe i ka titanium a me ka hana ʻana i ka titanium dioxide. nā puaʻa ʻole. ʻO ka puaʻa keʻokeʻo ka mea ikaika loa, me ka mana huna maikaʻi a me ka wikiwiki o ka waihoʻoluʻu, kūpono i nā huahana keʻokeʻo opaque. He kūpono loa ke ʻano rutile no ka hoʻohana ʻana i nā huahana plastik waho, hiki ke hāʻawi i ke kūpaʻa māmā maikaʻi. Hoʻohana nui ʻia ʻo Anatase no nā huahana i loko, akā he kukui uliuli iki, keʻokeʻo kiʻekiʻe, ka mana huna nui, ka kala ikaika a me ka hoʻopuehu maikaʻi. Hoʻohana nui ʻia ka Titanium dioxide e like me ka pena, ka pepa, ka pulupulu, ka plastic, enamel, aniani, cosmetics, ink, wai kala a me ka ʻaila kala puaʻa, hiki ke hoʻohana ʻia i ka metallurgy, radio, ceramics, electrode |
