  • Calcium phosphate porous material with small amount of remaining aromatic hydrocarbon
    Patent number: 8747791
    Abstract: The purpose of the present invention is to provide calcium phosphate porous material with small amount of the remaining polycyclic aromatic hydrocarbons that are toxic substances. The present invention relates to a method for the production of calcium phosphate porous material of ?-tricalcium phosphate comprising calcining micronized ?-tricalcium phosphate wherein a temperature in a furnace is retained at a temperature in a range of 250-550° C. for a certain period of time, or wherein a temperature-rising rate in the furnace while in said range is decreased to one thirds or less of that during ranges before or after said range in said calcining step.
