This work doped Sr(NO3)2 and Cr(NO3)3 to β-tricalcium phosphate(β-TCP)particles by sol-gel combustion method.Ca2+ions of β-TCP were substituted by Cr3+ions and Sr2+ions.The purpose of this study is to obtain high density porous structure material for the development of medical biomimetic bone material by research the crystal structure variation,biocompatibility and degradation properties in vivo of Sr,Cr-substituted β-TCP.
