Abstract Bredigite has an ideal composition close to Ca7Mg(SiO4)4 and a structural formula indicating co-ordination numbers, X[12] X 2 [9] Y 4 [10] M[6] [TO4]4 (T = tetrahedrally co-ordinated ion). Experiments show that Ba or Sr can replace Ca in the large X[12] sites while Mg in the M site may be partially replaced by Mn2+. When X[12] sites are occupied by two different ionic species, partial site ordering occurs. Bredigite-structured phases may occur in periclase refractories and high-Mg cement clinker. Ca-Mg bredigite reacts slowly with water; data on its hydration behaviour at 20 and 200
