Rutile is an oxide mineral composed of titanium dioxide (TiO 2), the most common natural form of TiO 2. Rarer polymorphs of TiO 2 are known, including anatase, akaogiite, and brookite. Rutile has one of the highest refractive indices at visible wavelengths of any known crystal and also exhibits a particularly large birefringence and high ...

金红石 （英語： rutile）是一种主要成分为 二氧化钛 的 矿物，在矿物学上属于金红石族 [2]。 属于四方晶系，是二氧化钛最稳定的型態。 此外，二氧化钛的 同质多象 变体还有 板钛矿 、 锐钛矿 和 赤荻石 （英语：akaogiite） 等。 其英文名称起源于 拉丁语 rutilus， 由18世纪德国著名地质学家维尔纳命名，意为“浅红色” [3]。 金红石属于 TiO 2 的三个同质多象变体之一，也是在自然界分布最广的那个。 常含Fe 2+ 、Fe 3+ 、 Cr 、 Nb 、 Ta 、 Sn 等 类质同象 混入物。 其中富含Fe时被 …

Rutile is a titanium oxide mineral with a chemical composition of TiO 2. It is found in igneous, metamorphic and sedimentary rocks throughout the world. Rutile also occurs as needle-shaped crystals in other minerals.

2024年7月1日 · Rutile is a mineral composed primarily of titanium dioxide (TiO2). It is one of the three main minerals of titanium, along with ilmenite and leucoxene. Rutile is commonly found in igneous rocks, metamorphic rocks, and certain types of sedimentary rocks.

锐钛矿（anatase；octahedrite）是 二氧化钛 （TiO2）的三种矿物之一。 它产于火成岩及变质岩内的矿脉中，一般还出现于砂矿床中，呈坚硬、闪亮的正方晶系晶体，并具有不同的颜色。 许多锐钛矿是由榍石风化形成的，而且它本身可蚀变为金红石；TiO2类质同象替代有Fe、Sn、Nb、Ta等。 此外，尚发现含Y族为主的 稀土元素 及U、Th。 晶形一般呈锥状、板状、柱状。 它产于 火成岩 及 变质岩 内的 矿脉 中，一般还出现于 砂矿 床中，呈坚硬、闪亮的正方晶系晶体，并具有不 …

Rutile, the most abundant of three naturally occurring forms of titanium dioxide (TiO2; see also anatase; brookite). It forms red to reddish brown, hard, brilliant metallic, slender crystals, often completely surrounded by other minerals. Rutile is a commercially important titanium mineral,

Rutile is one of the five forms of titanium dioxide, TiO 2, found in nature. Sellaite (magnesium fluoride, MgF 2) also has a rutile-type structure. Compare 'UM1987-04-O:Ti'.

2023年9月7日 · Rutile is a critical ore for titanium, which is an essential component of lightweight, strong, corrosion- and temperature-resistant metal alloys used in everything from bicycles to spacecraft. It...

2010年9月1日 · Rutile has a wide range of applications in earth sciences. It is a major host mineral for Nb, Ta and other high field strength elements, which are widely used as a monitor of geochemical processes in the Earth's crust and mantle.
