Preparation method of three-dimensional communicated porous calcium-phosphorus biological ceramic
The invention provides a preparation method of a three-dimensional communicated porous calcium-phosphorus biological ceramic, which comprises the following steps of: regulating and controlling the etching time and the etching times of dilute acid of an etching agent by utilizing etching pits generated by multiple short-time chemical etching to control the number and the size of the etching pits; calcium-phosphorus biological ceramic is generated through solid-phase reaction of heavy calcium carbonate and calcium hydrophosphate, and surface corrosion pits become holes due to crystal growth; volatile gas generated in the calcining process of solidified unsaturated resin in the artificial agglomerated stone waste residues is utilized to form a gas channel. The porous calcium-phosphorus biological ceramic prepared by combining a chemical etching method and a calcining method can obtain a porous microstructure and form a three-dimensional communicated pore channel. The method is beneficial to resource utilization of the artificial agglomerated stone waste residues, and the porous calcium-phosphorus biological ceramic which is three-dimensionally communicated and has the pore diameter of a mesoporous structure is prepared and belongs to a high-performance functional material.
本发明提供了一种三维连通多孔钙磷生物陶瓷的制备方法，利用多次短时间化学浸蚀产生的蚀坑，调控浸蚀剂稀酸浸蚀时间和浸蚀次数来控制蚀坑的数量和大小；根据重质碳酸钙与磷酸氢钙固相反应生成钙磷生物陶瓷，表面蚀坑由于晶体生长成为孔洞；利用人造岗石废渣中的固化不饱和树酯在煅烧过程中产生的挥发性气体形成气体通道。通过化学浸蚀法和煅烧法相结合制备多孔钙磷生物陶瓷可获得多孔微结构，形成三维连通孔道。本发明有助于人造岗石废渣资源化利用，并且制备三维连通、孔径为介孔结构的多孔钙磷生物陶瓷，属高性能功能材料。
