| titleOfInvention | Tetracalcium phosphate nano powder for 3D printing and capable of enabling printed bone finished products to have high pore connectivity and preparation method thereof |
| abstract | The invention discloses a preparation method of tetracalcium phosphate nano powder for 3D printing and capable of enabling a printed bone finished product to have high pore connectivity, which comprises the following steps: (1) mixing rare earth compound, calcium salt, sodium chloride and water; (2) mixing a rare earth compound, a titanium source and water, and then synchronously dripping the mixture and water glass into the mixture in the step (1); (3) sealing the reactant prepared in the step (2), heating to 120-; (4) mixing the electropositive layered silicate prepared in the step (3) with water, then adding calcium carbonate and calcium hydrophosphate, uniformly mixing, heating to 150-; (5) and (4) filtering the reaction liquid obtained in the step (4), washing to obtain a filter cake, roasting the filter cake at the temperature of 400-600 ℃ for 60-90min, cooling, and grinding until the granularity is not more than 200 meshes to obtain the catalyst. The tetracalcium phosphate nano powder has excellent pore connectivity. |
