The invention discloses a method for preparing a hydroxyapatite block, which comprises the following steps: adding hydroxyapatite powder into pure water, and performing cold sintering and tableting treatment to obtain a hydroxyapatite block; The solid-to-liquid ratio of apatite powder to pure water is 1g:(0.1‑0.3)ml; in the cold sintering tableting process, the pressure is 8-10MPa, the temperature is 80-120°C, and the tableting time is 18-22h . The invention can prepare monocrystalline high-purity hydroxyapatite blocks without the participation of surfactants under low temperature conditions, thereby improving the purity of the products. |
