| 摘 要： | 使用水基羟基磷灰石(HA,Ca5(PO4)3OH)浆料,用冰模板法制备定向层状多孔HA陶瓷,研究了浆料中HA陶瓷颗粒含量和冷端温度的影响.结果表明:随着浆料中HA陶瓷颗粒含量的提高,浆料的粘度值增大,层状多孔结构的层厚度相应增加,孔道层间距减小甚至消失,多孔材料的抗压强度从1.4 MPa提高到5.7 MPa,孔隙率从7...

| Abstract: | The porous ceramics with unidirectional lamellar pore structures was prepared by icetemplating of aqueous hydroxyapatite(HA,Ca_5(PO_4)_3OH) slurry,and the effects of content of the solids loading and the temperature of the cold finger were investigated.The results show that the viscosity of the suspensions increased as content of the solids loading increased.The lamellar thickness increased along with the decreasing porosity from 76.2%to 44.2%.The compressive strength increased from 1.4 MPa to 5.7 MPa.With ... |
