Titanium
钛
Titanium is a transition metal which is very strong and light (4.4 gm/cm3). It has a high melting point (1800°C) and finds application in aircraft wings, particularly at points which are subjected to the high heat of exhaust.
钛是一种过渡金属，非常坚固且轻盈（密度为4.4克/立方厘米）。它具有很高的熔点（1800°C），常用于飞机机翼，特别是在承受高温的部位。
Titanium dioxide in powder form is very white and is used to advantage as a pigment in special paints and face powders. Titanium dioxide, TiO2, in crystalline form appears in the mineral rutile. It may be colored by small amounts of other metal oxides and has been used for gems. Titanium dioxide also makes up the minerals Brookite and anatase. Titanium and iron together form the oxides ilmenite, FeTiO3, and pseudobrookite, Fe2TiO5. Titanium and calcium form the oxide perovskite, CaTiO3. Titanium and calcium form the silicate titanite, CaTiSiO5, which can form gem-quality crystals. Lithium and sodium are found with either zirconium, titanium or hafnium in the mineral zektzerite. Titanium appears with manganese and arsenic in the mineral cafarsite
Titanium is found in the minerals aeschynite, euxenite and
astrophyllite. Titanium forms an oxide mineral with lead, iron and manganese called senaite. Another oxide with boron (borate) with iron and titanium is warwickite. Antimony and titanium are contained in the oxide romeite. Titanium is found in the silicate minerals joaquinite, wilhuite and neptunite.
钛存在于矿物aeschynite、euxenite和astrophyllite中。钛与铅、铁和锰形成一种氧化物矿物，称为senaite。另一种含硼（硼酸盐）的氧化物矿物，含有铁和钛，称为warwickite。锑和钛存在于氧化物romeite中。钛还存在于硅酸盐矿物joaquinite、wilhuite和neptunite中。
Titanium tetrachloride is a liquid at room temperature, but if it is sprayed into the air, it hydrolizes to form HCl and fine particles of titanium dioxide. It has been used for making smoke screens. A spray of titanium tetrachloride is used for "skywriting" from aircraft.
四氯化钛在常温下是液体，但如果将其喷入空气中，会水解生成HCl和细小的二氧化钛颗粒。它曾被用于制造烟雾弹。从飞机上喷射四氯化钛可用于“写天”（skywriting）。
二氧化钛以粉末形式非常白，常用于特殊涂料和粉底霜中作为颜料。二氧化钛以晶体形式出现在矿物 rutile 中。它可能因少量其他金属氧化物而着色，并曾用于制作宝石。二氧化钛也构成了 Brookite 和 anatase 这两种矿物。钛和铁共同形成氧化物 ilmenite（FeTiO3）和 pseudobrookite（Fe2TiO5）。钛和钙形成氧化物 perovskite（CaTiO3）。钛和钙还形成硅酸盐 titanite（CaTiSiO5），它可以形成宝石级的晶体。锂和钠在矿物 zektzerite 中与锆、钛或铪共存。钛在矿物 cafarsite 中与锰和砷共存。 |
