C0188200 (sĕl′ĭ-stīt′, sə-lĕs′tīt′)n. A white, red-brown, orange, or light blue principal strontium ore, essentially strontium sulfate, SrSO₄, found in sedimentary rock. Also called celestine.

[celestine + -ite.]

celestite

(ˈsɛlɪˌstaɪt) or

celestine

n (Minerals) a white, red, or blue mineral consisting of strontium sulphate in orthorhombic crystalline form: a source of strontium compounds. Formula: SrSO4[C19: from German Zölestin, from Latin caelestis celestial (referring to the blue colour) + -ite¹]

cel•es•tite

(ˈsɛl əˌstaɪt)

also cel•es•tine

(-stɪn, -ˌstaɪn)

n. a mineral, strontium sulfate, SrSO₄, occurring in white to pale blue crystals: the chief ore of strontium. [1850–55; celest(ine) (< German Zölestin < New Latin coelest(is), for Latin caelestis celestial + German -in -in¹) + -ite¹]

celestite

(sĕl`əstīt) or

celestine

(sĕl`əstĭn, –tīn), mineral appearing in blue-tinged or white orthorhombic crystals or in fibrous masses. The natural sulfate of strontium, SrSO₄, it is important as a source of strontium and of certain of its compounds, e.g., strontium hydroxide, used in refining beet sugar, and strontium nitrate, used in red signal flares. It occurs in England, in Sicily, and in the United States on islands in Lake Erie and also in Pennsylvania, New York, and Ohio.

Celestite

a mineral of the sulfate class, with the composition SrSO₄. Celestite often contains admixtures of Ca and Ba. It crystallizes in the orthorhombic system, forming tabular or columnar crystals. Its segregations are often in the form of nodules or concretions, in which the mineral forms fibrous or granular aggregates. Celestite’s color, which is due to various point defects of the crystal structure, may be light blue or gray-blue, with a red or yellow tinge, but it disappears upon heating. The density is about 4,000 kg/m³, and the hardness is 3.0–3.5 on Mohs’ scale.

The primary deposits usually occur in limestones, dolomites, and gypsum, in which celestite is associated with sulfur, rock salt, aragonite, and calcite. The principal deposits in the USSR are located in Middle Asia, the Volga Region, and the southern Urals. There are also major deposits in Great Britain, the Federal Republic of Germany, the United States, and Italy. Celestite is a raw material for the production of strontium compounds, which are used in the sugar, glass, ceramics, and pharmaceutical industries, in the production of pyrotechnics, and in metallurgy for the manufacture of special alloys.

celestite

[′sel·ə‚stīt] (mineralogy) SrSO₄ A colorless or sky-blue mineral occurring in orthorhombic, tabular crystals and in compact forms; fracture is uneven and luster is vitreous; principal ore of strontium. Also known as celestine.
