Title CALCIUM-BASE METAL GLASS ALLOY MOLDED BODY FOR MEDICAL USE, AND PRODUCTION METHOD THEREOF
Abstract The purpose of the present invention is to provide a production method of a calcium-base metal glass alloy molded body for medical use which is bioabsorbable, has mechanical strength equivalent to or greater than that of metal materials, allows complex molding and can be applied to a wide range of uses. The calcium-base metal glass alloy molded body for medical use is produced by mixing a metal powder containing a calcium powder, alloying said mixed powder, and sintering the alloyed mixed metal powder.
