Machinability study of single crystal sapphire in a ball Fabrication of novel bioresorbable β tricalcium phosphate

Abstract Sapphire has received increasing attention as an engineering material even though its machinability is still an issue In this study the influence of the milling process parameters on the surface quality of single crystal sapphire is investigatedThe β TCP cement with compressive strength of 13MPa was fabricated from the finelyground β TCP powders prepared by ball milling commercially available β TCP powder for 4h using zirconia beads with 10mm in diameter Meanwhile the β TCP/CDAp biphasic cement had maximum compressive strength of about 23MPa among the examined cement specimens it was fabricated from the ball milled
