PURPOSE:To obtain the title hydraulic pellet easy to handle and capable of being easily filled into a region to be filled by pelletizing a specified composition into the pellet having specified compression strength. CONSTITUTION:Tetracalcium phosphate and calcium phosphate having <1.67 atomic ratio of Ca/P are mixed so that the Ca/P atomic ratio of the mixture is controlled to 1.3-1.8. The hydraulic pellet having <=20kg/cm<2> compression strength is formed from the mixture. The pellets can be easily filled into the region to be filled, the pellet can be easily collapsed after filling by exerting a weak pressing force, and the pellets can be surely filled into the region to be filled with high filling density. |
