| A method of manufacturing calcium silicates, calcium aluminates, calcium aluminosilicates and calcium ferrites and the products thereby derived utilizing molten-salt synthesis and/or molten-salt sintering. Molten-salt synthesis enables efficiently manufacture calcium silicate (Ca—SiO3), dicalcium silicate (Ca2SiO4), tricalcium disilicate (Ca3Si2O7) and related compounds such as calcium aluminate (CaAl2O4), Gehlenite (Ca2Al2—SiO7) and tetracalcium aluminoferrite (Ca4Al2Fe2OO10) at temperatures in the range of about 400-750° C. The composition of the synthesized product(s) can be varied by altering the ratio of the precursor compounds and by changing the molten-salt composition, whether used as a sintering flux or molten bath, resulting in the ability to manufacture calcium silicates and related compounds for a wide variety of uses, but most specifically as precursors to the manufacture of hydraulic cements or for use in hydraulic cements such as Portland cements and calcium aluminate and other cements. | ||||||

| A hydraulic cement for biomedical applications. The cement sets in-situ, hardening when exposed to water to produce nano-dispersed composite of calcium-silicate-hydrate gel mixed with hydroxyapatite. In comparison with prior cements, the composition provides high biocompatibility, high bioactivity and high biomechanical strength, due to the composite structure of the calcium silicate hydrate reinforced with co-precipitated particles of hydroxyapatite. Biocompatibility is also increased due to an absence of aluminum and magnesium in the composition. The cement is suitable for variety of applications, including dental implants, bone fixation, and bone repair. | ||||||
