PREPARATION METHOD OF NANO SIZED beta-TRICALCIUM PHOSPHATE POWDERS IN HIGH PURITY USING ELECTRON BEAM IRRADIATION

摘要

PURPOSE: A method for producing nanosize beta-tricalcium phosphate powder of high purity is provided to use for manufacturing organic or ceramic materials. CONSTITUTION: A method for producing nanosize beta-tricalcium phosphate powder of high purity comprises: a step of dissolving calcium hydroxide(Ca(OH)2) and phosphoric acid(H3PO4) in deionized water then adjusting pH at 11-13; a step of irradiating to the mixed solution to produce beta-tricalcium phosphate powder; and a step of calcinating the powder at high temperature.
