Hydroxyapatite microcrystalline glass and preparation method thereof

The invention discloses hydroxyapatite microcrystalline glass. The hydroxyapatite microcrystalline glass is prepared from 39.79-44.73% of SiO2, 12.38-13.86% of Al2O3, 22.68-25.15% of CaO, 1.41-7.61% of MgO, 4.75-9.06% of P2O5 and 8.82-9.83% of the rest of components. According to the microcrystalline glass, waste water deposition serves as the main raw material, the processes of solid-liquid separation, washing, drying and the like are not needed, the hydroxyapatite microcrystalline glass can be rapidly prepared, a new thought is provided for recycle of waste water deposition, waste is turned into wealth, the preparation cost of the hydroxyapatite microcrystalline glass is reduced, the prepared hydroxyapatite microcrystalline glass is wide in application prospect, added value is high, industrialized application and popularization are facilitated, and power is provided for recycle of enterprise waste water deposition.
