Latest Patents

Fukamachi's latest patents focus on a calcium-phosphate type hydroxyapatite designed for chromatographic separation. This innovative material is characterized by spherulites with a mean particle diameter ranging from 0.5 to 50 micrometers, ideally between 1 to 10 micrometers. Each spherulite is an aggregate of acicular crystallites belonging to a series of hexagonal systems, with specific unit lattice constants of 9.58 ± 0.08 Å for the a axis and 7.00 ± 0.05 Å for the c axis. The hydroxyapatite is produced by granulating a calcium-phosphate type hydroxyapatite in gel form and subsequently firing the granular apatite at temperatures between 400°C to 700°C, preferably at 500°C to 600°C, in the presence of oxygen or air.
