Strontianite is a mineral that has the chemical formula SrCO3. The word is pronounced as /ˌstrɒnˈtiːənaɪt/, with the stress placed on the second syllable. The initial consonant cluster in the word is 'str,' pronounced as a voiceless alveolar fricative /s/ followed by an alveolar trill /r/. The second syllable contains the diphthong /iːə/, which is pronounced with a long "ee" sound followed by a schwa sound. The final syllable 'naite' is pronounced /naɪt/ and contains a long vowel sound followed by a voiceless velar stop consonant.
Strontianite is a noun that refers to a mineral composed mainly of the carbonate form of strontium, known as strontium carbonate (SrCO3). It belongs to the category of carbonate minerals and is generally categorized as a member of the aragonite group. This mineral is named after the place where it was first discovered, Strontian in Scotland.
Strontianite typically crystallizes in the orthorhombic crystal system, often forming prismatic or tabular crystals. These crystals, however, are relatively rare and typically occur in globular or granular aggregates. The mineral commonly exhibits a translucent to transparent appearance and may occasionally display a pale green, gray, yellow, or white color. Its luster is usually vitreous or pearly.
Strontianite is primarily formed in sedimentary environments rich in strontium. It is often found associated with other minerals like celestine, fluorite, and calcite. Although it has limited uses compared to other minerals, strontianite is a significant source for extracting strontium, which finds applications in various industrial, medical, and scientific processes. It is particularly valued in pyrotechnics, fireworks, and electronics industries where its compounds are used for their luminescent properties and as catalysts.
In conclusion, strontianite is a mineral composed mainly of strontium carbonate. It has distinct crystalline forms and is found primarily in sedimentary environments. Its significance lies in its strontium content, which is used in various industrial applications.
The carbonate of strontia, a mineral of an apple-green or yellowish-brown colour, occurring in variously-modified hexahedral prisms, and in fibrous granular masses.
