采用碳酸钙、碳酸锶和磷酸氢钙为起始原料,经高温固相反应合成制备了不同含锶量(0%、5%、10%、15%和20%(原子分数))的羟磷灰石无机骨水泥粉剂,以丙烯酸-衣康酸共聚液和柠檬酸的混合液为骨水泥固化液,探讨不同含锶量对骨水泥可注射性的影响。结果表明0%、5%、10%和15%(原子分数)含锶量试样组的物相结构为含锶的羟磷灰石和α-TCP。20%(原子分数)含锶量试样组的物相结构则为含锶的羟磷灰石和β-TCP,并且不具有水化凝固的特性。随着含锶量的增加,骨水泥的注射性能也变得更好。当粉液比采用1.8g/g时,0%、5%、10%和15%(原子分数)试样组骨水泥的可注射率分别达到46%、74%、100%和100%,由此表明锶的掺入可以明显提高羟磷灰石无机骨水泥的可注射性。
採用碳痠鈣、碳痠鍶和燐痠氫鈣為起始原料,經高溫固相反應閤成製備瞭不同含鍶量(0%、5%、10%、15%和20%(原子分數))的羥燐灰石無機骨水泥粉劑,以丙烯痠-衣康痠共聚液和檸檬痠的混閤液為骨水泥固化液,探討不同含鍶量對骨水泥可註射性的影響。結果錶明0%、5%、10%和15%(原子分數)含鍶量試樣組的物相結構為含鍶的羥燐灰石和α-TCP。20%(原子分數)含鍶量試樣組的物相結構則為含鍶的羥燐灰石和β-TCP,併且不具有水化凝固的特性。隨著含鍶量的增加,骨水泥的註射性能也變得更好。噹粉液比採用1.8g/g時,0%、5%、10%和15%(原子分數)試樣組骨水泥的可註射率分彆達到46%、74%、100%和100%,由此錶明鍶的摻入可以明顯提高羥燐灰石無機骨水泥的可註射性。

The powder of different strontium-containing(0,5at%,10at%,15at% and 20at%) hydroxyapatitc bone cements were synthesized from strontium carbonate, calcium carbonate and calcium phosphate dibasic by solid reaction. A mixed solutions that consisted of copolymer of acrylic aeid/itaeonic acid and citric acid were used for setting liquids. The injectability for different strontium-containing bone cements were investigated. The experiment results show that the structure of phases for groups of 0,5at%,10at%,15at% strontium a mount were a series of strontium-containing a-TCP/HA biphases cement by the analyses of XRD and FT-IR, but that of group of 20at% was the strontium-containing 13-TCP/HA biphase, and which had non solidification. The injectability were more good with the increase of strontium amount. When powder to liquids rates was 1. 8g/g, the injectability of groups of 0,5at%, 10at% and 15at% were 46%,74%, 100% and 100% ,respectively.
