  • Phase evolution and sintering kinetics of hydroxyapatite synthesized by solution combustion technique.: This study discusses the phase evolution and sintering behavior of hydroxyapatite, a critical material in bioceramics, emphasizing the chemical processes involved during synthesis by solution combustion, which might include the usage of di-Ammonium hydrogen phosphate as a precursor (Pratihar et al., 2006).


  • An investigation of the chemical synthesis and high-temperature sintering behaviour of calcium hydroxyapatite (HA) and tricalcium phosphate (TCP) bioceramics.: This article investigates the synthesis routes for bioceramics like hydroxyapatite and tricalcium phosphate, potentially utilizing di-Ammonium hydrogen phosphate in their production processes, focusing on their behavior under high temperatures (Taş et al., 1997).
