natro-|ˈneɪtrəʊ, ˈnætrəʊ-|comb. form of natrium, used in Min. to form the names of sodium-containing minerals (as natrolite), and also prefixed to existing mineral names to indicate the (often partial) substitution of sodium for some other metal in that mineral, as natroˈalunite, any of the range of basic sulphates of sodium, potassium, and aluminium, (Na,K)Al₃(SO₄)₂(OH)₆, which have the proportion of sodium greater than that of potassium and are found as white hexagonal crystals; spec. the sodic end-member of this series; natroˈchalcite [L. chalcītes chalcites], a basic hydrated sulphate of sodium and copper, NaCu₂(SO₄)₂(OH).H₂O, which is found as emerald-green monoclinic crystals at Chuquicamata in Chile; natroˈdavyne [ad. It. natrodavyna (F. Zambonini 1910, in Atti d. R. Accad. d. Sci. fis. e mat. XIV. vi. 188)], a silicate and carbonate of aluminium and sodium, found as colourless hexagonal crystals; natroˈjarosite, a basic sulphate of sodium and iron, NaFe₃(SO₄)₂(OH)₆, found as yellow or brown hexagonal crystals; ˌnatromonteˈbrasite [a. F. natromontebrasite (F. Gonnard 1913, in Bull. de la Soc. franç. de Min. XXXVI. 120)], a basic fluoride and phosphate of sodium, lithium, and aluminium, (Na,Li)Al(PO₄)(OH,F), with more sodium than lithium, which is found as whitish triclinic crystals.1902Hillebrand & Penfield in Amer.
