About: Brockite

An Entity of Type: mineral, from Named Graph: http://dbpedia.org, within Data Space: dbpedia.org:8891

Brockite is a rare earth phosphate mineral with formula: (Ca,Th,Ce)PO4·H2O. It crystallizes in the hexagonal system in the chiral space group 180 or its enantiomorph 181. It is typically granular to massive with only rare occurrence of stubby crystals. It is radioactive due to the thorium content.
