| 摘要: |
| 对ＲＯ Ａｌ２Ｏ３ Ｐ２Ｏ５ 系统玻璃中某些组分进行了去离子水及模拟生理液的耐蚀性测定．实验表明，ＲＯ Ａｌ２Ｏ３ Ｐ２Ｏ５ 在模拟生理液中的侵蚀规律异于通常的Ｎａ２Ｏ ＣａＯ ＳｉＯ２ Ｐ２Ｏ５ 生物玻璃．试样的红外光谱验证了在该玻璃中兼有ＰＯ３ 和Ｐ２Ｏ７ 基团，具有稳定的Ａｌ（ＰＯ３）结构单元． |

| Abstract: |
| Chemical durability of selected compositions in RO Al 2O 3 P 2O 5(RAP) glass system(R=Zn,Mg) in deionic water and simulated physiologic solution were measured respectively. The measurements showed that the corrosion mechanism of RAP glass is quite different from that of Na 2O CaO SiO 2 P 2O 5 bioglass.The results from infrared spectrum experiments have confirmed the existence of PO 3 and P 2O 7 groups,as well as the stable Al(PO 3) group in the structure of RAP glass. |
