Combustion synthesis and photoluminescence study of silicate biomaterials

Abstract

Silicate based bioceramics are promising candidates as biomaterials for tissue engineering. The combustion synthesis method provides control on the morphology and particle size of the synthesized material. This paper discusses the combustion synthesis of akermanite (Ca2MgSi2O 7 and Sr2MgSi2O7), which has been shown to have good in vitro and in vivo bioactivities by earlier studies. Both Ca2MgSi2O7 and Sr2MgSi 2O7 have akermanite structure. Ca2MgSi 2O7 and Sr2MgSi2O7 were prepared using urea and ammonium nitrate. The combustion synthesis using urea and ammonium nitrate was found to be cost effective and efficient method of synthesis. The photoluminescence study of Ca2MgSi2O7: Eu2+ and Sr2MgSi2O7: Eu2+ shows host specific intense emission of Eu2+. © Indian Academy of Sciences.
