The new mineral fluoroceramic silicate apatite is produced in Mont St, Quebec, Canada. Hilaire area, occur in the nepheline syenite, marble xenoliths, sodalite syngenetic xenoliths and pegmatite dikes. The main associated minerals are cubic zeolite, slightly plagioclase, aegirine, zircon, biotite, red titanium manganese, aspartate, cesium-cerium ore, natrolite, monazite and so on. Fluoro cerium silicon apatite crystals hexagonal columnar; pale yellow to brown yellow; streak colorless to light brown; diamond gloss; translucent to opaque; hardness of 5; parallel to the degree of cleavage of {0001} moderate; measured relative The density was 4.66 (1) g / cm3, and the calculated relative density was 4.66 g / cm3. The uniaxial crystal was negative, ω = 1.792 (5), ε = 1.786 (5). Its crystalline formula is: (Ca1.77Ce1.35La0.96Nd0.21Na0.21Mn0.15Sr0.09Pr0.08Th0.05Y0.02Sm0.01) 4.90 (Si2.17P0.79) 2.96O11.95F1.05; the ideal structural formula (REE, Ca) 5 (Si, P) 3O12F. Fluoro cerium silicon apatite is a hexagonal system with space group P63 / m. The unit cell parameters are: a = 9.517 (5), c = 6.983 (4), c / a = 0.7337, V = 547 (8) 3, Z = 2. X-ray powder diffraction data and their relative intensities are: 2.845 (100), 2.747 (10), 1.966 (10), 1. ?
