Production of α-TCP Ceramic Precision Spheres for Mosaic-Like Ceramics Fabrication Use

Abstract

Kay Teraoka and Katsuya Kato

Profile accuracy of spherical ?-TCP ceramics (artificial bone units) was improved by a precision fabrication method named “hydro-casting.� Hydro-casting shapes ?-TCP slurry into spherical shape by dispensing definite quantity of ?-TCP slurry in an oil and fixing the slurry’s shape by two-stage gellation. Resulting ?-TCP spheres exhibit almost uniform shape and interunit gaps that would establish schematic features of porous body fabricated by “Mosaic-like ceramics fabrication (MLCF).�
