摘　　要：分别采用液相和气相发泡法制备了可注射的多孔硼酸盐生物玻璃基骨水泥(BBGC)。比较了2种发泡方法对骨水泥注射性、抗压强度、孔隙率、抗溃散性和降解性能的影响。研究表明:2种发泡方法制备的BBGC均具有优异的注射性能,注射率达90%。但液相发泡法制备的BBGC样品抗压强度可达(4.28±1.05)MPa,在抗压强度和抗溃散性方面优于气相发泡法。气相发泡法制备的BBGC的开口孔隙率达40%,高于液相发泡法的27%。浸泡产物的X射线衍射和红外光谱分析表明:2种发泡方法制备的BBGC均能矿化生成羟基磷灰石Ca_(10)(PO_4)_6(OH)_2,但是气相发泡法制备的BBGC的矿化性能优于液相发泡法。The injectable and porous borate bioactive glass cements （BBGC） were prepared by liquid- and gas-foaming method, respectively. The effect of foaming strategy on the BBGC performances, including injectability, compressive strength and anti-washout ability were investigated. The results indicate that the injectability of BBGC prepared by both the strategies is superior to over 90%. Besides, the compressive strength, anti-washout ability of BBGC prepared by liquid-foaming method are superior to those by gas-foaming method. The compressive strength of BBGC with total porosity of 70%prepared by liquid-foaming method can reach 4.28±1.05 MPa. However, the open porosity of BBGC prepared by gas-foaming method is 40%, which is greater than that by liquid-foaming method （27%）. The BBGC prepared by both methods can react with PBS and form Ca10（PO4）6（OH）2 on the surface while the BBGC prepared by gas-foaming method presents a more excellent mineralizing ability.
