Cerite is a complex silicate mineral group containing cerium, formula (Ce,La,Ca) 9 (Mg,Fe 3+)(Si O 4) 6 (SiO 3 OH)(OH) 3. [3] The cerium and lanthanum content varies with the Ce rich species (cerite-(Ce)) and the La rich species (cerite-(La)). [5] [6] Analysis of a sample from the Mountain Pass carbonatite gave 35.05% Ce 2 O 3 and 30.04% La 2 O ...

Cerite mineral data, information about Cerite, its properties and worldwide locations.

The meaning of CERITE is a mineral consisting of a hydrous silicate of cerium and allied metals occurring generally in brownish masses (hardness 5.5, specific gravity 4.86).

Calculated Properties of Cerite-(Ce) Electron Density: Bulk Density (Electron Density)=4.34 gm/cc note: Specific Gravity of Cerite-(Ce) =4.86 gm/cc.

2020年12月28日 · The cerite supergroup (Atencio and Azzi, 2020) consists of two groups of isostructural trigonal R3c (no. 161) minerals , namely, cerite (silicates) and merrillite (phosphates) groups.

2020年10月30日 · The cerite supergroup is established and includes the cerite group (silicates) and merrillite group (phosphates). Cerite-group minerals are cerite-(Ce), ferricerite-(La), aluminocerite-(Ce) and taipingite-(Ce).

Cerite was synthesized from hydrosilicates which were precipitated in the ratio M 2+:M 3+ (i.e., rare earth): M 4+ (i.e., Si) = 2:7:6. The precipitates were centrifuged, washed, dried, and in some experiments admixed with carbonates.

cerite, (Ce,La,Nd,Ca)e(Fe3*,Mg,AlXSiO4)6(SiO3OHXOH)3, rhombohedral, a 10.779(6), c : 38.061(7) A, Z : 6, space group R3c, is nearly isostructural to whitlockite, CaqMg(PO+)o(PO3OH). R : 0.032 for 1711 independent reflections. Cerite is related to a large family of "bracelet and pinwheel" structures derived from glaserite, KNal(SOn)2.

CERITE definition: a rare mineral , the hydrous silicate of cerium | Meaning, pronunciation, translations and examples

Pinkish garnet-like grains of Cerite-(Ce) embedded into olive-green microgranular Tornebohmite-(Ce) (most rich by it places are the bottom central part of the specimen and along the left side of black Ferriallanite-(Ce) veinlet).
