$Cu^{2+}$ eklenmiş hidroksiapatitlerin yüksek sıcaklıkta sinterlenmesi ve iç yapı incelemesi

Saf ve $Cu^{2+}$ eklenmiş hidroksiapatitler (HA) çöktürme metodu ile üretildi. 1100°C’deki atmosferde yapılmış olan sinterleme sonucunda, $Cu^{2+}$ iyonlarının HA’nın iç yapısına ve ısısal dayanımına olan etkileri araştırıldı. Element analizleri göstermiştir ki çöktürme metodunda $Cu^{2+}$ iyonlarının HA’ya eklenmesi işlemi yüksek pH (=11) seviyelerinden dolayı kısıtlanmıştır.$Cu^{2+}$’nin HA’ya katılması, HA’nın hegzagonal kafes parametrelerini değiştirmiştir. $Cu^{2+}$’nin eklenmesi, 1100°C’deki sinterleme sonucunda daha küçük tanecik boyutuna sahip olunmasına neden olmuştur.

High temperature sintering of $Cu^{2+}$ doped hydroxyapatites and microstructural investigation

Pure and $Cu^{2+}$ doped hydroxyapatites (HA) were synthesized by a precipitation method to investigate the effect of $Cu^{2+}$ ions into the structure of HA and thermal stability after the air sintering at 1100°C. Elemental analysis showed that doping of $Cu^{2+}$ ions into HA was limited because of the high pH (=11) during the precipitation method. $Cu^{2+}$ addition into HA changed the hexagonal lattice parameters of the HA. $Cu^{2+}$ addition resulted in smaller grain size after the sintering at 1100°C.
