Le corindon, ou oxyde d'alumine [...] est utilisé comme abrasif et dans ses variétés les plus nobles, comme gemme. Selon la couleur bleue ou rouge, il est appelé saphir ou rubis. [...] Les premiers pays producteurs de corindon abrasif sont l'Afrique du sud et la Grèce. Le rubis et le saphir proviennent essentiellement de Birmanie, Thaïlande, Ceylan [...] Du point de vue géochimique, le corindon est considéré comme un minéral de haute température, dans des roches cristallines riches en alumine et pauvres en silice; [...] 4, record 1, French, - corindon

Il est probable que la leverriérite se forme «in situ» sous faible tranche d'eau en milieu lagunaire. Elle subit un léger transport et se répartit ensuite sans grand déplacement suivant les courants et les fonds. L'origine du matériel est volcanique malgré la rareté de matériaux pyroclassiques qu'elle renferme. 3, record 2, French, - leverri%C3%A9rite

SECAR 41 is a hydraulic binder with an alumina content of approximately 47% and an iron oxide content of approximately 5%. [It] is composed mainly of calcium aluminate phases, which makes it an ideal binder for refractory applications. SECAR 41 is particularly rich in monocalcium aluminate ... which imparts excellent properties to mortars and concretes. 3, record 4, English, - monocalcium%20aluminate

The most important cement compounds formed on fusion are monocalcium aluminate (CA) and tricalcium pentaluminate (C3A5); furthermore, some pentacalcium pentaluminate and small amounts of dicalcium aluminosilicate, dicalcium silicate, and tetracalcium aluminoferrite are also present. Both monocalcium aluminate and tricalcium pentaluminate hydrate initially to a gel CaAl2(OH)8·6H2O, which gradually changes to a very stable, crystalline complex Ca3Al2(OH)10·3H2O and a gel of aluminium hydroxide Al(OH)3. 4, record 4, English, - monocalcium%20aluminate
