Kinetics and mechanisms of the transformation of precipitated amorphous calcium phosphate with a Ca/P ratio of 1:1 to calcium pyrophosphates

Autor: D. Rokhmistrov, Anton Goncharenko, Z. Zyman

Publikováno v: Journal of Crystal Growth. 478:117-122

The kinetics and mechanisms of crystallization, phase transformation and grain growth in amorphous calcium pyrophosphate (ACPP) derived from the fast nitrate synthesis were studied at 600–800 °C. The high-temperature calcium pyrophosphate α-CPP c

Phase evolution during heat treatment of amorphous calcium phosphate derived from fast nitrate synthesis

Autor: V Anton Goncharenko, V Dmytro Rokhmistrov, Z. Zyman

Publikováno v: Processing and Application of Ceramics, Vol 11, Iss 2, Pp 147-153 (2017)

The phase evolution in amorphous calcium phosphate (ACP, with a Ca/P ratio of 1 : 1), derived from the fast nitrate synthesis using different conditions, was studied in temperature range 20-980?C. ACP crystallized within 600-700?C and the phase compo

Peculiarities in thermal evolution of precipitated amorphous calcium phosphates with an initial Ca/P ratio of 1:1

Autor: Matthias Epple, Anton Goncharenko, D. Rokhmistrov, Z. Zyman, Oleg Prymak, Kateryna Loza

Thermal evolution of amorphous calcium phosphate (ACP) powder from a fast nitrate synthesis with a Ca/P ratio of 1:1 were studied in the range of 20–980 °C. The powder consisted of amorphous dicalcium phosphate anhydrate (CaHPO4) after heating to

Sodium-carbonate co-substituted hydroxyapatite ceramics

Autor: Mykola V. Tkachenko, Z. Zyman

Publikováno v: Processing and Application of Ceramics, Vol 7, Iss 4, Pp 153-157 (2013)

Powders of sodium-carbonate co-substituted hydroxyapatite, having sodium content in the range of 0.25-1.5 wt.% with a 0.25 wt.% step, were prepared by a precipitation-solid state reaction route. Compacts of the powders were sintered in a CO2 flow (4
