General description

Thermal decomposition of calcium citrate tetrahydrate in dynamic air or dry nitrogen has been investigated by by TG, DTA and DSC.

Application

Calcium citrate tetrahydrate may be used as raw material in the preparation of nanoparticle with the nominal composition Ca0.8 Ba0.2 Ti03 :Pr3+, via sol-gel process. It may be employed as carbon source in a simple and effective carbonization method to prepare porous carbon without any activation process. It is suitable for use in the preparation of bovine serum albumin (BSA) nanoparticles.
